Innotek IUC-5100 Overview

Summary: Dog Fence + Remote Trainer

The Innotek IUC-5100 combines both a dog containment and a remote training system in a single collar. The Innotek IUC-5100 is $40 more than it’s sibling system, the PetSafe Ultrasmart, and gets you the remote trainer functionality plus 100 feet of the twisted wire.

Remote Trainer

The unique feature on the Innotek IUC-5100 is that the collar can be used with the included remote to allow you to correct your dog. The remote has a minimal range so is not useful for training hunting dogs, but is a perfectly functional remote trainer for basic obedience training.

Larger Collar

The tradeoff for the remote trainer is that the collar is about 50% larger than the collar on the sibling Petsafe Ultrasmart system. The collar is only suitable for dogs over 20 lbs.

Rechargeable Collar

The Innotek includes a rechargeable lithium ion collar battery. A charge takes less than two hours and last around a month (in dog fence mode) .

Collar Fit Test

The collar has a inbuilt test to help you check if the collar is properly fitted on the dog. This is particularly helpful for long-hair dogs where fitting the collar can be tricky.

Innotek IUC-5100 Collar

Containment + Training Collar

The unique feature on the Innotek IUC-5100 collars is that it can be used both for containment and correction. If you are going to use a training collar and containment system with your dog, the IUC-5100 lets the dog wear only a single collar.

Training Collar

The collar on the IUC-5100 can be used in conjunction with the included remote transmitter. This allows you to correct your dog by pressing a button on the remote. This kind of negative stimulus is useful as a training aid to reinforce training commands.

Note, that as with dog containment – these remote trainers are only effective when used as part of a structured training program. You need to teach the dog what you do want them to do, and only then do you layer on the correction to teach them there is a consequence for not obeying a command. Correcting a dog without training will only create a fearful dog with no improvement in behavior!

The collar always runs in containment mode. Training mode is activated by holding the collar next to the remote and holding down a button.

Larger Collar

The tradeoff for the additional training collar functionality is that the collar is bigger than the otherwise identical PetSafe Ultrasmart system. To accommodate the extra circuitry and sensor, the collar is 50% bigger, although the weights are around the same (4.4 ounces vs 4 ounces).

The extra bulk of the collar makes it unsuitable for dogs under 20 lbs. The PetSafe Ultrasmart which does not have the remote trainer can be used with dogs as small as 12 lbs.

Rechargeable Lithium Ion Battery

The 5100 collar is rechargeable. The sits on a charging cradle to charge. The cradle is included. When the collar is fully charged, the status lights changes from red to green. The 5100 collar requires a 2 hour charge one a month.

The battery and collar have shown over time to last a very long time. This collar has been tested in the field by thousands of customers and has proven to last 6 plus years. Once the collar battery can no longer hold a charge, the great thing is that for around $35 plus shipping, you can receive a new collar.

3 Progressive Correction Levels

The Innotek Contain & Train has three correction levels when used in containment mode. A few more correction levels would be ideal to allow more customization. However, the correction levels are progressive, meaning that the correction strength automatically increases the further the dog goes into the correction zone.

The correction levels on the Innotek range from low to medium-high and will suit most dogs. Particularly hard-headed and less sensitive dogs would benefit from a stronger collar such as the Dogtek EF-6000 or the PetSafe Stubborn.

Short Training Battery Life

While the battery life is long when the collar is used for containment, battery life is considerably shorter when training mode is activated. When in training mode, the collars need recharging at least every 3 days.

No Independent Correction Levels

The Innotek 5100 does not allow you to set different correction levels for each dog. This can be an issue if you have two very different sized dogs or two dogs with very different temperaments. There is one solution you could use. It requires fastening a resistor to the collar probes to decrease the correction strength.

Rubber Collar Band

The IUC-5100 collar fastens with a rubbery collar band. The fastener is a gimmicky combination buckle and quick-snap style. We would prefer a cloth band and a simple-quick snap collar.

Long, Short & Training Prongs

The basic system includes both long and short prongs for use with long and short hair dogs respectively. The prongs are easily interchanged using the supplied tool to unscrew the old prongs and fasten the new prongs.

The system also includes two yellow caps that can be placed over the prongs to prevent them from correcting. You will use these in the early stages of containment training when you want to teach the dog the new boundaries without shocking them.

Innotek IUC-5100 Remote


The handheld remote allows you to trigger the correction on the dog collar and allows you to use the system for obedience training.

9 Correction Levels + Beep

The remote has 9 correction levels, plus a beep only level. The correction level can be adjusted using the arrow keys on the remote.

The correction level is shown on the LCD screen in the center of the remote. The LCD is not backlit. Which makes it hard to see at night.

Two Dog Capacity

The remote transmitter can control up to two IUC-5100 collars. The transmitter can be set to correct each collar individually, or both collars at the same time.

↑ Top


Using the collar for both teaching obedience and containment at the same time can ge confusing and overwhelming for your dog. We recommend teaching the containment first, then waiting three months for the dog to become confident with the boundary rules before starting to use the collar for obedience training. Teaching the dog the new containment rules, as well as doing obedience training w

50 Yard Range

The remote has a very limited range of around 50 yards. The manufacturer specifications claim a generous 150 yard range, in practice we find the remote becomes unreliable after 50 yards.

50 yards allows you to use the collar for basic obedience training in your yard or at your home. But, the range is not sufficient to use with your dog off leash at the park, or to using with a hunting dog. For these applications, you will need a dedicated training collar where ranges can exceed 2 miles.

Innotek IUC-5100 Transmitter


The base station powers the dog fence boundary wire and creates the radio signal that is picked up by the collars. The transmitter is the brains of the dog fence system. The Ultrasmart transmitter has all the regular features, plus a few extras.

25 Acre Capacity

The transmitter can create a boundary of up to 25 acres (around 5,000 feet of boundary wire). This makes it one of the highest capacity systems. If you need an even higher capacity, the SportDog SDF-100A can contain a 100 acre property.

Includes Lighting Protection Module

The Ultrasmart includes a lightning protection module standard with the kit. You run the boundary wire into the lightning protection before running it into the transmitter. This module protects the transmitter in case the boundary wire gets struck by lightning. This is particularly useful for large installations in areas where lightning strikes are common. Having the lightning protection included standard is a nice extra that is seen in few other systems and saves you $39.95.

↑ Top

Adjustable Boundary Only

The boundary zone, the distance between the boundary wire and the point where the collar starts beeping, can be adjusted using a dial on the transmitter. You can set the boundary width anywhere from a few inches to 10+ yards wide.

The correction zone, the distance from the boundary wire that the collar starts correcting the dog, is always set at 80% of the boundary zone. Unlike the Dogtek systems, the boundary zone cannot be independently set.

Battery Backup

The transmitter has a battery backup so it will keep working even if there is a power outage. Insert 8 AA batteries in the back of the unit and if there is a power failure, you get 2-3 days of power before the batteries are drained.

Battery backup is a useful feature in places where power outages are common. But, for most urban dwellers with reliable power this is not terribly useful. If power failures are only occasional, your dogs will not realize that the fence is off.

Innotek IUC-5100 Wire and Accessories
Dog Fence Wire Gauges

Boundary Wire

Direct Burial Rated Wire

The included boundary wire is direct burial rated, having a PET insulation layer that is designed for placement directly into the ground. Direct burial wire lasts longer in the soil than standard electrical wire which tends to disintegrate over time (particularly in acidic soil condidions).

Professional Gauge Wire Available

The standard 20 gauge wire can be upgraded to 18, 16, and 14 gauge wire. 14 gauge wire is considered professional grade and is what you would see on an Invisible Fence installation. With professional grade, the copper wire and protective insulation are both four times thicker and stronger than the standard wire. This makes the wire stronger and more durable and therefore less likely to break.

For small installations, upgrading the wire is a no-brainer. A modest additional cost reduces the likelihood of you needing to hunt for wire breaks.

For very large installations, the thicker gauges of wire are useful because of their superior transmission characteristics. However, the additional cost becomes significant.

Standard 500 Feet of 20 Gauge Wire

The Innotek basic system includes enough 500 feet of standard 20 gauge wire, 50 boundary flags, and 2 wire splices. The included wire can cover approximately one-third of an acre. Additional boundary kits (500 feet of wire, 2 splices, and 50 flags) are available and can expand capacity up to 25 acres (5,000 feet).

Area (acres) Wire Required (feet)
1/3 500
1/2 1,000
1 1,000
2 1,500
3 2,000
4 2,000
5 2,000
10 3,000
15 4,000
20 4,500
25 5,000

Tester Tool

The included tester tool is held against the collar to test whether the system is working. When everything is set up properly, the tester lamp will glow as you take the collar across the boundary line.

Innotek IUC-5100 One Year Warranty

One Year Warranty

Innotek systems are covered by a limited one year warranty. What this means is that the systems has a limited one year warranty on the system, and then for the rest of the lifetime of the system repairs are made at a nominal charge.

↑ Top


If you want a single collar with both containment and remote training functionality, the Innotek IUC-5100 is a good bet. For $40 more than the standard PetSafe Ultrasmart, you get a remote trainer which is a great deal.

There are tradeoffs for the added functionality. The IUC-5100 collar is bulkier than comparable training only collars, and the training function is more limited than dedicated training collars.

Hello, I would love to be able to use the electric fence with our husky. He weighs 120 pounds and had a 100 by 150 foot area to play in. My question is, how well do these products work under the frozen ground? The ground would be frozen for roughly 4 months of the year.

ADMIN – Hi Linda. What state do you live in? Our sales and support are limited to the United States coverage area. Therefore, we are required to only do business and process shipments within the United States.

We have the ICU 5100, the same blue collar (although slightly larger) as the Petsafe Ultrasmart but with the remote trainer, can I still use the remote trainer and old collars with Yardmax or which central gate might work with those collars, like is there a frequency adjuster, etc? To me the remote trainer is very very valuable, and one collar for both uses, yard and other places. When we take them to the public beach, we use the remote trainer beep to call them back when they get too far away, and we also use the trainer beep to call them to the house for dinner when they are out who’s knows where in our yard, if they do something wrong we can use static discharge using the remote, it works this way for our Black Labs but if it’s discontinued…. I’m looking for a way to make this “system with the trainer” work with yardmax or whatever is the best replacement using the same Waterproof collar, because they do swim in the pool, lake or ocean on our property every day.

ADMIN – Hi Mike and Karie. Unfortunately, PetSafe bought out Innotek and all of the Innotek products are going away. This includes the Innotek UltraSmart IUC 5100 Contain n Train. The replacement collars are not being made any more. We recommend training your dog(s) on the electric dog fence for 30 days before introducing a remote trainer. This is to avoid confusing the dog with too many instructions. Have you visited the DogFenceDIY Dog Training Collar Website?

Justyn September 23, 2014 at 12:22 pm

I have the IUC-5100. Lately, the collar has been making a discharge noise, either a short beep/buzz or a light static-sounding buzz. The collar is about 3 years old. I am at a loss for what to do next. Could the battery be going bad? it still displays a green light flashing, so I’m not sure if it’s the battery or not. Is the battery replaceable? Please let me know your recommended next steps.

ADMIN – Hi Justyn, unfortunately, the Innotek 5100 has bee discontinued. The best course of action is to contact PetSafe directly to discuss changing out your fence for another fence. I would recommend the PetSafe YardMax for a great replacement of the 5100 dog fence.

Mike July 23, 2014 at 9:01 pm

Hi, I purchased an Innotec 5100 System for my 2 dogs in March. I bought the fence and an extra collar. One of my dogs managed to get her collar off and thoroughly destroyed the receiver. So now I need a new collar, and am shocked to find that Innotek has discontinued the 5100 system. How am I to get a replacement collar? Are there other collars compatible with the 5100 fence?

ADMIN – Hi Mike, you will want to contact PetSafe directly for system and collar replacement. They are offering a 30% discount off the total order to switch your system to the PetSafe YardMax. Luckily this will not require reinstalling your dog fence wire.

Matt from Delaware July 22, 2014 at 2:17 pm

Installed the 5100 system in the winter along a 4 foot wire mesh fence within a dense private hedge. Though my installation is well under 1,000 feet, I had to switch to the large field setting in order to get a consistent signal. Perhaps because I used the thick 14 gauge wire? The signal is now consistent, but our large husky’s undercoat is so dense that the long probes do not make consistent contact with his skin–even when his hair is trimmed and the collar is tight. This is not the fault of the manufacturer–it’s just part of owning a dog designed to withstand sub-zero temperatures. The system still works for us, because the physical barrier of the fence and hedge slows him down enough that occasionally he receives correction from the collar. However, without the physical barrier, the system would never contain him. Even after careful training, he was on the highway in a flash when I left the gate open. He has since learned the boundaries, and does not test them even when a rabbit or deer tries to entice him. Now that he has learned the boundaries, I need to keep him out of certain areas. My question is this: Does the Pawz Away rock work with the collar in regular containment mode, or do I have to switch the collar to “training” mode?

ADMIN – Hi Matt, yes the Outdoor Rock is compatible with the Innotek IUC5100 collar and it will work in regular containment mode. All you would need to do is put batteries into the Rock and adjust the radius of the signal. The collar should automatically work with the Rock.

Wendy May 18, 2014 at 8:01 pm

We purchased the Innotek 4100 in late 2011 for our two labs. The systems works great but the collars have been problematic as they are often falling off. At first, I found this to be a nuisance but now I am just plain annoyed by the amount of time it takes to search my 2 acre wooded property. I have even tried to secure the collars with clips to no avail. My dogs seldom venture off the property any more but it is a safety concern. I just finished reading a review on Amazon where a dog was hit by a car because the collar fell off. Anyone have any recommendations?

ADMIN – Hi Wendy, PetSafe has discontinued both the 4100 and 5100. The best course of action is to contact PetSafe directly. You can upgrade into the PetSafe YardMax which addresses the collar problem you mentioned.

Kelsey March 19, 2014 at 12:02 pm

We have 2 puppies (both should end up between 60-70 lbs). We want a system that can give us a containment area for our yard and the remote training capability. I think the UltraSmart IUC 5100 sounds like the right system, but I’m not sure. Are there other systems that also offer both? The remote trainer on this system says it will work for up to 2 collars. What if I want to get a 3rd back-up collar to have charging while the other 2 are being worn, will I still be able to use the single remote? We live next to a farm that uses above ground electrical wire to contain their cows. Will that wire interfere with our in-ground system? Will I need to move the wire further into my yard?

ADMIN – Hi Kelsey, when you want to use the 3rd collar, you would deactivate one of the collars and activate the collar to sync with the 3rd collar instead. The electrical fence wire should not hinder the dog fence much. Sometimes, it will decrease the signal slightly. For the most part you can effectively install the dog fence wire 4 feet from the electrical wire.

leslie March 17, 2014 at 4:37 pm

I have a rescue lab who enjoys digging out under our fence. Even with exercise he thinks it’s so funny to get out of the fence and watch me chase him down the road. He is spends most of his time in the house getting extra special attention but when he really enjoys being outside rolling in the grass and soaking up the sun. Right now my only option is putting him on a chain for 30 minutes at a time(UGH I HATE DOING THAT!) but he enjoys being outside so much. I am hoping running an underground fence before my actual chain link fence will deter him from digging underneath so he can enjoy the outdoors more. I have a 6 year old lab that doesn’t want out of the fence but I am always afraid he might pick up the new dogs bad habits so I am interested in having 2 collars. These are fairly large labs with very thick hair. I am looking to fence 3/4 of an acre total. I need something that is reliable in power outages because we loose our power regularly even on a beautiful sunny day. Is this product the best option for me?

Is the remote trainer something that I can use if he ends up escaping out the front door or does it only work inside the fence?

Also I have a neighbor about 300 feet from me using an underground fence, will that cause interference?

Thank you!

Daren March 9, 2014 at 5:27 pm

Hi. I currently have the petsafe ultrasmart 4100. I know the collars are compatible with both systems but I was wondering if the training remote from the 5100 system would work with the 4100 system? If so where can I purchase one. Thanks

Toni January 22, 2013 at 7:48 pm

Is a Innotek 300 collar compatible with an Innotek 5100 system?

ADMIN – Hi Toni, Unfortunately no. The only other collar compatible with the unit is the PetSafe Ultrasmart collar.

Joe November 13, 2012 at 10:30 am

I have the 5100 and it has stated to flash red and green with a tone. It says the receiver will need to be recharged soon? Collar is charged so what else is going on?

Admin- Hi Joe,

The red and green light problem you are experiencing sounds like your reminder switch is confusing the transmitter. Checked the position of the switch that is located in-between the two blue dials on the wall transmitter. That switch needs to be turned to the bottom position, which is off.The reminder switch does not serve a purposes at this time and it will confuse the transmitter.

helen October 10, 2012 at 6:40 pm

HI – we just installed the innotek 2000 for our Siberian husky – we put on the longest prongs that came in the package – and currently he is barreling thru the fence to get to the female dog down the street. We’ve checked the system and we know it works – but he’s ‘fast’ and ummm ‘determined’ – lol – what would our options be? can we upgrade to the 5100 or 4100 for the brain box and collar?

ADMIN – Hi Helen, unfortunately there are no upgrade options. I’d recommend shaving his neck so that the contact points make good contact with his skin. The collar should fit snugly.

Kristyn September 29, 2012 at 2:07 pm

We are interested in purchasing a wired fence system for our 18 lb miniature schnauzer who is head over heels for chasing rats, squirrels, rabbit; just about anything that moves. We are moving out onto 5 acres and I was wondering which system would be best for him as he is as stubborn as they come. He has a lap dog pet me pet me temperament, and I am concerned about ruining his disposition from receiving the consequence. We are trying to avoid having to install regular fencing since we will be in a gated community with HOA restrictions as far as appearance of the property. I have read and read about all of the different models and such, but I have gone there in the past only to be disappointed with the purchase. What would you suggest for our little pooch? We would also like more than a 5 acre range.

ADMIN – Hi Kristyn, for his size he is way to small for a Stubborn collar. The PetSafe Ultrasmart PIG00-13619 offers plenty of correction levels to suit your Schnauzer and it’s rechargeable.

shane September 26, 2012 at 9:22 pm

I have just purchased a 7 week old Great Dane. Should be around 170lbs. Will the 5100 work on this big of a dog

ADMIN – Hi Shane, with such a big dog, I would recommend the SportDog SDF100A. This system has the same collar as the Stubborn fence but is more robust.

Dawn September 18, 2012 at 10:37 am

Ok I have two dogs one a German Shepperd and the other is a Jack Russell. My questions revolve around the space in which the dogs will be contained in (as they do not play well together). I have two yards one all around my home and one across the street from my home. I want to keep the Jack Russell in the yard around the house and the German Shepperd across the street. Will I have to buy two separate systems? And the dogs are on opposite ends of the size chart so will this require different settings for correction? Does anyone make one system that can do all which I require?

ADMIN – Hi Dawn, if you can connect the two loops with twisted wire, you then can use one fence system. If you cannot, then you will need to purchase two systems. For your mix of dogs, I recommend going with the PetSafe Stubborn fence with a Deluxe collar added in.

Anna September 14, 2012 at 9:16 am

Hi, we purchased the Innotek IUC-5100, and it works great for us. But we have 3 cats that we would like to let outside safely. We have a 3-acre yard and the dog fence goes around the perimeter of the yard. What is our best option for the cats? Can we simply add the PetSafe cat collars? Or do we need to install a separate PetSafe Underground Cat fence (we could make it much smaller than the dog fence so they don’t overlap). Any suggestions would be helpful. Thanks!

ADMIN – Hi Anna, unfortunately the 5100 is not compatible with the cat collars and I fear the 5100 collar is too big for the cats. If you install separate systems you will experience interference between each.

JD August 19, 2012 at 9:47 pm

Looking to get a 5100 system. Question regarding the remotes training function. I have three Chow Chows who will each be getting a collar. Does it provide three remote controls/trainers or does one set a different freq for each dog/collar. Ie, if a dog needs correcting down the line or is not behaving, and you use the remote, do all three dogs get corrected or is it specific per collars… especially when all three are in the same general area. Also, got a question regarding the wire. I have a 5 ft chain link perimeter fence around 3.5 acres. I also have a large kennel up against the perimeter fence lined with rock underground to prevent digging and escape. Is it possible to wire the whole 1500 feet of perimeter, but not the back of the kennels? The kennel is around 30 x 75 ft and I don’t want to “shrink” the size of the kennel by the range of the perimeter wire barrier distance. Hope the question is understood. TIA. JD

ADMIN – Hi JD, The 5100 remote works with up to 2 collars at one time. You can correct the two separately. In order to exclude the kennels, you’ll need to run a double boundary loop. This will have one wire along the ground with the second wire running along the top of the fence. You would then bring the two wires together and twist them when you pass the kennels in order to cancel the signal there.

Can I change the battery on the 5100 when it dies out, or do I need to send it in to Innotek? Should I be concerned when there is lightning-does the wire fence increase the chance that lightning strikes near my house? Thanks!

ADMIN – Hi Peter, when your collar battery eventually dies, you’ll want to buy a replacement for a discount through the manufacture as long as you have a receipt of purchase from an authorized retailer, which we are. I don’t believe that your fence increases the chance of lightning.

I have three pole barn buildings and am curious if they will affect this system? I have heard that other systems do not work properly with metal buildings. Thanks

Admin- Hi Bill,

The metal barn will not effect the Innotek IUC5100 transmitter if you have twsted wire leading out to the property line. The only time we have experienced any issues with metal barns and a wired in-ground system, is when the boundary wire(not twisted) is ran along side the sheet metal sides. The signal can reflected off of the sheet metal.

Hello, We are considering purchasing this fencing system for our 45 lb Aussie Cattle Dog / Golden mix as we move to a new house. We will not have a large yard, so we want to know what kind of boundary space we will need from where the wires are our to the middle of the yard. Our neighbor told us it’s a pretty wide boundary so the dog will not have much room to run in the yard. Is this true? Also, can we only put wires around 3 sides of our yard, or do you need all 4 sides to form a consistent loop? Thanks!

ADMIN – Hi Dawn, The system does require a complete loop. There are many layout options that can work with any containment layout goal. You can reach these layouts under the drop down menu under “Dog Fence Installation” tab. Click on “Planning/Layouts” The boundary is set up at the wall transmitter. You can set the distance from the wire as low as 3 feet from the wire if you have minimal space.

Hello, We are getting ready to move into a new house and I am considering the 5100. We have two dobies, one is five months and the other is five years. We also have a small jack Russell but I am considering letting her roam since we are in the country. I notice that the 5100 doesn’t have correction levels. Dobies are very sensitive to punishment and I think a lower correction would be sufficient but I am not sure. Isn’t the correction level setting in most collars? Wouldn’t it make sense to sell a collar that would work for the 5100? What is the best alternative to the 5100 that has remote training? Thanks a lot!

ADMIN – Hi Matt, The correction levels are set at the wall transmitter and there are three levels of correction. You are just unable to have different levels of correction for each dog. For your mix of dogs, I’d recommend the PetSafe Deluxe fence for your Doberman’s with either a Deluxe collar for your Jack Russell if he’s over 12 lbs or the PetSafe Little Dog collar if the Jack Russell is under 12 lbs. This way you can set each collar to their own correction level. Currently, there is no alternative fence offering remote correction.

SCOTT July 6, 2012 at 2:35 pm

Would the innotek IUC-5100 be a good option for a Chessie?

Admin- Hi Scott,

Absolutely, the IUC-5100 system will work great for your Chesapeake Bay Retriever.

Tammy Hash July 1, 2012 at 8:56 am

Hi, I am moving to a new location and an underground invisible fence is my only option. I have a 5 year old Great Pyrenees and a 2 year old hound, mutt mix. The 5 year old should do well with one, but the little one is just bad ! She is just very hyper all of the time and runs around like she’s crazy. She is always figuring out ways to escape, which is odd because I have a 6 foot privacy fence around my current home. We actually had to build a horizontal base around our fence because she kept digging to get out! She is about 25 lbs, and the 5 year old is 70 lbs. What fence do you suggest? And how much is the extra collar for the systems? And are these dogs trainable? I’ve had them both for quite a while and they do not take well to any type of training. Petsmart wouldn’t even work with the little one.

ADMIN – Hi Tammy, The key to successful pet containment is in the training, not the fence or correction strength. You’ll want to keep good discipline as well during training, meaning that during the 2 to 3 weeks of training, you’ll need to make sure you’re Pyrenees and Hound are not off leash. The reason is that you don’t want them to have the opportunity to cross the dog fence boundary. This will undo the training. Second, if your hound isn’t catching on to training, you have to keep working with them until she displays the proper behavior, which in this case is, when they hear the warning beep or receive a static correction they are to turn around and retreat back into the yard. Because of your Hound mix, I’d recommend the PetSafe Stubborn fence. It has the strongest correction levels for a dog fence which you’ll need for your crazy, escape artist. The additional collars for this system are, as of 7-2-12, $74.95 each. Every dog is trainable, it just takes plenty of discipline and patience on the part of whose training. Also, we do have a 30 day no hassle return policy, so it gives you the opportunity to give a dog fence a try and be able to return it for a full refund if necessary.

david pozzo June 19, 2012 at 8:59 am

I currently have a Petsafe invisible fence system. My dog got out of the boundary and when he returned, he was no longer wearing his collar. Can I buy a Innotek collar that will it work on the Petsafe system?

Admin- Hi David,

Sadly the Innotek Collars are only compatible with the PetSafe/Innotek 4100 and Innotek 5100 transmitters. The only options for replacement collars on most PetSafe transmitters will be the PetSafe Stubborn dog, Little Dog, and Deluxe collar.

Chris May 31, 2012 at 4:53 am

Thanks for all the great info on your website. After a good bit of research, I’m inclined to go with the Innotek 5100 but was hoping you could comment on a couple of items first:

1. What has your experience been in regard to reliability of the 4100/5100 collars? I’ve seen a number of comments from users around the internet that have had some significant problems in regard to battery life. Many seem to have to replace the collar after only a year (and some after only a few months!).

2. How is the range and reliability of the remote function on the 5100? I know Innotek claims 150 yds but what have you seen most users getting in the real world? What about lag issues? I certainly recognize that it won’t be equivalent to a good quality dedicated remote collar, but I’m only looking for basic functionality to reinforce voice commands in the yard as well as reinforce recall when on off leash walks.

Admin- Hi Chris,

1) We have not seen too many issues with the collar not holding a charge; however, if you do experience issues with the collar or transmitters. You will receive a full one-year warranty followed by a limited lifetime warranty through the manufacturer if you purchase your fence from an authorized retailer like us. You will always be covered if any issues arise. The last time we checked the replacement collars through the limited lifetime warranty is between $30-$40 to replace.
2) The IUC5100 hand held remote will work well up to 75-100 yards and is very reliable in typically atmosphere and terrain. Lag has not been an issue within 75-100 yards.

Kathryn April 21, 2012 at 10:47 am

Hi, we have decided to install electric fence for our dogs. We have a 3.5 yr old American Eskimo male – stubborn, dominant, will not come when called – 35 lbs at the heaviest. We just got a now 4 months old American Eskimo female, who is currently approaching 15 lbs, but should grow up to 30lbs.

I’m wondering if we install it for for the older dog, get another collar for the younger one, but don’t use it on her yet. She comes when called still, and pretty much stays with us even when he runs off unless we say okay. I’m thinking maybe we just keep her electric fence training on hold until she’s bigger – since the correction level can’t be adjusted. Alternatively, I’ve seen comments about a resistor to lessen the correction on one collar – if done can it be undone?

I’m not interested in the remote training aspect, as I already have a standalone remote training collar I’ve purchased 2 months ago and am still reluctant to try by myself. Have been working w/ a professional trainer on the older dog and we have come to the conclusion that’s the best way to go w/ him – I’m waiting for her to coach me! So, I think it would be a waste for us to invest in that capability again.

My husband will install it, but I have to get it. :o) We would so love to be able to talk to someone to understand the right way to do this. Do you guys talk live?

Thank you!

Admin- Hi Kathryn,

The Innotek IUC4100 or IUC5100 systems will work great for your two dogs. We could send out the Resistors that will be applied to the collar to reduce the correction amount by 50 or 75 percent. The resistor will simply twist between the collar probes; you will be able to remove the resistor once applied.
You do have live phone support. Feel free to gives us a call anytime. We are always happy to talk with our customers. DogFence: (888) 936-4349

Brandon April 2, 2012 at 8:34 pm

Does the Innotek 5100 shock collar that comes with the system work outside of the fence also? If I wanted to take my dog to the lake down the road- would it work there too? I don’t plan on hunting or anything with my lab but I would like to be able to use the shock collar function if we go on trips and what not.
Also, my neighbors have an underground fence that is an old brand not offered anymore- how can I be sure that there will not not be a frequency problem between the two causing a break in mine?

ADMIN – Hi Brandon,

The remote trainer does indeed work outside the fence.

Without knowing more about the neighbor’s fence, it is hard to say if there will be cancellation of the signal across the company boundary. The safest way to play it, would be to use a dual frequency system like the Perimeter Ultra – but this is not going to give you the remote trainer you want. Otherwise, the only way to find out would be to test a section with a Innotek 5100 unit.

Paul Mitri March 19, 2012 at 10:25 am

I have installed 600 feet of boundary wire. 500 feet of 18 gauge and 100 feet of 20 gauge is there any problem with this set up?

ADMIN – Hi Paul,

Mixing gauges results in the correction zone being wider in the area with the thicker wire. Since the two wires you are using, 18 gauge and 20 gauge, are so similar you will not notice much difference and should not expect any problems. What should be avoided is mixing very different wires, such as 14 gauge and 20 gauge.

Carlos March 18, 2012 at 9:16 pm

Why should I buy Ultra Smart IUC instead of buying a $3,000.00. system. I know it is cheaper. Give me another reason.

ADMIN – Hi Carlos,

I presume what you are asking is why buy a DIY system like the Ultrasmart, rather than a professionally installed system like Invisible Fence or Pet Stop. Price is usually the biggest consideration, the DIY systems are cheaper upfront, and also don’t have recurrent battery subscription costs if you get something rechargeable like the Ultrasmart. There are also some extra features on the Ultrasmart like the collar check function that you don’t get on other systems. And finally, lots of our customers just plain like figuring things out and doing the project themselves rather than relying on someone else.

The professionally installed Invisible Fence systems have the advantage that someone comes out to your house and does all the installation for you. It is much quicker and easier to have their team, that does this type of work every day, come to your house and do it for you.

Both the Innotek and the Invisible Fence systems are good choices. It just depends on what is right for each family’s situation.

Mel March 14, 2012 at 10:32 pm

We are researching fences for our Rottie. She is currently 5 months old and we would like to have a fence ready to start training boundaries when she turns 6 months or shortly thereafter. Our neighbors use a wireless fence for their dogs which provides a circle around the house and is not enough “space” for our girl to be ‘free.’ Therefore, the following questions:
1) Which in ground system would you recommend for a Rottie who has almost mastered the basic training – sit, stay, come – commands?
2) Do we need to be concerned about the frequencies the wireless system uses?

Thank you in advance.

Admin – Hi Mel,

1) The Innotek IUC4100 will work great for your Rotti and since she has already been able to understand all the basic commands. She is defiantly ready to train with a dog fence.
2) Your neighbors wireless system will not affect your boundary signal.

Geoff Gifford February 29, 2012 at 9:53 am

I have the 5100 system and just replaced two collars. How do I get the remote paired with the new collars?

ADMIN – Hi Geoff,

To pair the collar and remote, simply touch the training remote antenna to the top of the collar (where the blinking green light is). Hold down the green tone button for a few seconds to pair. Once the two are paired, you will notice that you now have two little lights blinking on the top of the collar.

brian February 20, 2012 at 10:04 pm

I just recently purchased the 5100. I was wondering if there is a wireless transmitter that works with the Innotek IUC-5100 collar as well. The wired system is needed for our home because the property is narrow but long. But wireless would be great for camping.

ADMIN – Hi Brian,

Afraid, there aren’t any wireless transmitters that will work with the Innotek wired system collar. Some of our customers will take the Innotek wired transmitter with them, and set out a temporary wired perimeter to keep their dog from wandering off when they go camping. This is a more clunky solution, but will work. The other option would be to get a separate wireless system for when you go camping. Something short range like the PetSafe Wireless, or the Havahart Radial should get the job done.

Mike F. January 30, 2012 at 6:21 pm

Hi I have a 6 month old Chihuahua / Pomeranian mix and he will most likely not get to be more then 16 or 17 lbs. I have a place upstate NY with lake front across the road in front of the house. I would like to use the wire to keep him on the main property which is about 2 acres and use the remote to keep him at the beach when we are there. Do you think this would be a good idea and would the innotek 5100 be a good choice. Thank you

ADMIN – Hi Mike,

Using the remote trainer function for containment rarely works out well. You have to be super vigilant and super consistent to get it to work – watching the dog and activating the correction in a timely manner every time they leave. Most people aren’t that consistent enough and only end up teaching the dog not to run away when they are looking.

You have the best chance of it working if you plan of training him on your main house first. Then put up the flags on the beach property and train the dog on that property.

The 5100 collar is also going to be a little on the big side for the dog. We usually use the 5100 collar for dogs over 20lbs. The collar will be bigger and heavier than is ideal. You may want to consider getting the compatible lighter 4100 collar for use at the main house when you don’t need the remote correction function.

Betsy January 27, 2012 at 5:37 pm

We need to contain and train our 1 1/2 year old 60lb. Rottweiler/Husky mix on our 200 acre farm. We have recently begun using a remote trainer to eliminate her jumping on people, chasing livestock, jumping on our doors to be let in the house, etc. She has responded well to the collar, but she very quickly learned that she can get away with those behaviors when she doesn’t have the collar on. This week she began running to our neighbor’s house a 1/2 mile away and making general nuisance of herself, so we are now in the market for an invisible fence. We also have a 5 year old German Shepherd who doesn’t roam. They both stay outdoors during the day while we are at work and come indoors when we are home. I’ve read many of the questions on your website which address some of my concerns, but I’d like to get some extra feedback on the following issues:
1) We plan to use about 4000 feet of wire to enclose the area around our house, which includes a lake along part of the border. We don’t mind our dog getting in the water, but we don’t want her to figure out how to “swim to freedom”. The water depth is around 5 to 10 feet within 10 to 15 feet of the shore. How deep can the wire be underwater and still be functional?
2) What is the best way to manage a situation where we want to contain the dog in the yard when we aren’t home but want to come in and out of the fenced area alot to access the rest of our farm with the dog when we are home? The Innotek 5100 sounds like the system for us since we can also use the remote training feature. I’m picturing taking off the collar to get passed the fence borders with the dog, then putting it back on to correct the dog with the remote trainer when she misbehaves outside of the fenced area around our house. Is this how we should anticipate using the collar?
3) Would you recommend training the German Shepherd to stay within the fence? In your experience, is there a problem with allowing one “uncollared” dog to stray a little beyond borders if the one wearing the collar has been properly trained to stay within the borders? Again, the GSD doesn’t roam far from the house, and I’d like to avoid the expense of an extra collar if possible.

I suppose we could just forget the whole thing and keep her in her dog run until she grows up in 4 or 5 years :) just kidding. Thank you so much for your input!

ADMIN – Hi Betsy,

(1) The range of the signal is similar in water as it is in the air – so with a typical boundary width you would not want the wire to be more than 3 feet below the surface. Although we don’t like depriving a dog of swimming time, we find it work better to run the wire either around the entire lake or to block it off. Training the dog to turn and retreat on the water is difficult because the dog cannot turn and retreat away from the fence as quickly in deep water. If you do want to enclose part of the lake, running the wire through an old hose pipe and floating it on the surface works best.

(2) Yes. You will need to take the collar off when you exit and reenter the property. You will want to get the dog into a routine, where you do the same thing every time. For example, remove the collar, give the dog a release command, and then open the gate. The first few times you will need to drag the reluctant dog through, after a few times they will understand that they are allowed through with your permission. More details in the Training –> Walking Your Dog Section.

(3) If you have a non-roamer, they don’t need a collared. In our experience the collared dog learns that they have different boundaries to the collared dog and excepts it. Unlike human children, they don’t seem to develop any deep neurosis about perceived ‘unfair’ differential treatment. Many cats learn to taunt dogs from the other side of the fence, dogs meekly accept this indignity.

Jay January 22, 2012 at 11:31 am

Hello, I have a 110# Rottweiler and was considering the 5100 or the petsafe stubborn. he is obedience trained but likes to wander the neighborhood and leave our grounds and return at his own will. he can be stubborn and i want to know what system you would recommend. Also how do your products compare to invisible fence which will cost me $800.00 more than your system.

ADMIN – Hi Jay,

With a Rottweiler, I would err toward the PetSafe Stubborn. I might be a more powerful correction than you need, but it is handy to have that extra power in reserve if you need it. Some Rottweilers need a strong correction to refocus their attention.

The systems are very similar to the Invisible Fence (PetSafe and Invisible Fence are owned by the same company). The big difference is that Invisible Fence is a lot more convenient than we are … they come out to your house, install the system and get you started on the training. We like Invisible Fence, we think they do a great job.

With out DIY systems, you need to put the system in yourself, and you need to use our training video to learn how to train your dog on the system. The tradeoff is that their systems are more expensive and require an ongoing battery subscription. Our systems are much cheaper, and in the case of the PetSafe Stubborn use a regular 9V battery.

In terms of the system themselves, there is very little difference. Both are good and with training will get the job done.

Ryan January 13, 2012 at 4:35 pm

Hi. I have two large dogs and am interested in a contain and train system. How does the remote work with two dogs? Ryan

ADMIN – Hi Ryan,

When using the Innotek Contain and Train with both dogs, you first pair each collar with the remote as per usual. Then you use a mode button on the remote. The remote lets you control one collar at a time, or both together.

Terra January 9, 2012 at 12:17 pm

Our 5100 unit registered a break recently. We picked up the RF choke and were able to track it down to a section of wire near a driveway. We replaced the entire section where the tone loss was to be sure all the damage was corrected. (The choke worked great) . The receiver is now holding steady showing that the fence is intact. The problem we are now facing is a very weak signal to the colars. With all settings set to the max, we aren’t getting a beep unless we are less than a foot above the wire when it is lying on top of the ground. All collars are fully charged, and we double checked with a brand new collar as well with the same results. We also double checked it using a receiver from another system we have with similar results. We also replaced a section of the twisted wire because of some visible damage to the insulation of that.

All connections (4 total) have been double checked for good contact including cutting ends off, stripping insulation and reconnecting wires. With nearly 1500′ of border, redoing the entire system is clearly the last option. I am thinking this might be a situation where we need to make separate loops for each 500′ section of buried wire and test accordingly. Any way to find where our “weak” spot is that is limiting the entire system?

ADMIN – Hi Terra,

I would start by testing to see if there is a problem with the collar. I would connect a small dummy loop (20 feet) to the transmitter and test to see if you can get the collars to trigger from a few feet away. That will eliminate the possibility that there is something wrong with the collar.

Then I would test to see if you might have the boundary level turned up too high – this can cause problems as the opposite sides of the fence start interfering with each other and it appears as if you have a really narrow boundary width. For 1500 feet, switch the boundary field size to large, but turn down the blue dial all the way to minimum, then up to 9 o’clock and test the boundary width. Have someone stand five feet back from the boundary and slowly increase the boundary width until the collar starts triggering (they will be alerted by the red light and beep on the collar, or if they were touching the probes the friendly little jolt they get).

Then test that the signal is actually going around the whole circuit (not up one strand of twisted wire, and down the other). Cut the wire somewhere out on the boundary – if the transmitter does not register a break, the problem was the twisted wire or the twisted wire splices and they needs checking.

Only if you have eliminated these easy fixes would I start replacing wire as a fix for a weak signal. As you mentioned, you may have a partial break somewhere. The best way to find them is to use the RF choke or wire break detector and listen for spots where the signal is weak. You can also splice in 500 foot segments one at a time until you find which one cures the symptoms.

Jason January 7, 2012 at 6:24 pm

The one issue I have with the invisible fence that I am currently using is my dogs tend to run through the correction field and then are outside the zone. Does the 5100 provide some kind of reassurance or new technology that will help prevent this from happening?

ADMIN – Hi Jason,

The Innotek IUC-5100 does increase the correction level as dogs run through. But, my experience has been that the ‘run-through protection’ technology does not add much.

If your dogs are running through, it is more likely a training issue or collar fit issue. As long as the old fence works consistently, then you should be able to train them with what you have. I would make the fence boundary a little wider, check the collars are fitted correctly so the dog is getting the correction, then go back and do some remedial training. A new fence on it’s own is unlikely to help.

neil January 4, 2012 at 7:47 pm

I have an innotek 5100 system and would like to purchase an extra collar but would like a cheaper alternative to the @$100 innotek collar. I don’t use the optional trainer feature just use the collar to contain the dog. Is there a generic collar that will work with my system? I would prefer to have a nylon collar with a quick release plastic buckle. Thank you Neil

ADMIN – Hi Neil,

Afraid the only other option that is compatible with the 4100 system is the Innotek IUC-4100 collar which is only slightly cheaper.

Dan January 2, 2012 at 11:55 am

I have a 7 month old German Shepherd dog. My neighbor has a wireless containment system for their dog. Will the innotek 5100 have any interference issues on the boundary by the wireless system? Thanks.

ADMIN – Hi Dan,

The signal from the wireless fences will not interfere with any wireless system. So your neighbor’s wireless system and your Innotek IUC-5100 will happily coexist.

Julia December 19, 2011 at 10:04 pm

Thinking about the 5100 with an extra 4100 collar for second dog. The receiver will be kept in the shop where part will run through some woods and around the perimeter of the farm. Part of it will have to go across phone and buried electrical lines. Is that OK as long as they run perpendicular to the fence lines?
I have read contradicting information about running the fence along side some electric horse fencing. How does that work?
Also, our house is steel-framed, which prohibits us from going wireless, which is what we wanted but were told that would cause major problems. Will it affect the Innoteck?
Will the dogs be able to wear the collars 24 hours a day?
What happens if they cross the fence? Can they get back in without a shock?
Thanks for your response!

Admin- Hi Julia,

1) You will not receive any interference from the buried utility if you cross the wire perpendicular.
2) You can install the wire next the electric fence. We have found that there will not be any interference issues between the two fences.
3) The only time you might experience interference with the metal structure is if the wire is running parallel to the metal wall in close proximity. If the system did have interference with the wall, you would notice that the signal would amplify; therefore, would you have a larger boundary in that area.
4) The manufacturer recommends taking the collar off after 12 hours. However, we have plenty of customers who own outside only dogs that require them to keep the collar on at all times. A small percentage of dogs develop a rash called Pressure Necrosis, but most dogs will be fine. We recommend checking the dogs neck weekly to keep an eye out for possible issues if you decide to keep the collar on 100% of the time.
5) If your dog did cross the fence, they would experience the same boundary upon retry.

Ben December 16, 2011 at 10:05 am

I just finished installing my fence yesterday. Upon testing the fence I am questioning its integrity. Above ground the fence worked; now I have to walk very slowly across the wire to activate the warning and / or shock. Sometimes it will just shock, sometimes it will just beep, other times it will do nothing. The dog is very smart I feel like she will figure out she can run across the fence and it wont shock her. Why would it do this?

ADMIN – Hi Ben,

There will be a little variability in the fence, but it should not be more than about a foot with a wired fence. If you are getting more than that there is likely something wrong. The most typical culprits are having the fence set up too narrow – you want it to be at least three feet wide on either side of the wire, preferably at least five feet. Neighbor’s dog fences can also cause inconsistent fields. As can having your boundary width turned up so high the opposite sides of the fence starting interfering with each other. You are right to get this sorted out before you start training. Having a consistent field is important to the training process and makes everything much faster and easier on the dog.

With the training, the dog will never learn that they can run through and will assume it continues on indefinitely.

Hunt November 13, 2011 at 11:16 pm

My property lays out similar to lake option 3. How deep in the lake can you put the wire? Is 15 ft too deep? I was just thinking of putting cInderblocks at the corner, is that how you would do it? Thanks

ADMIN – Hi Hunt,

It depends on your goal. Lake option 3 is set up where the wire in the water is sunk to the bottom. We do recommend running the wire through a water hose and then sinking it into the lake. The fence will operate on the other boundaries even if it is 15 feet in the water.

frank November 13, 2011 at 11:58 am

hi i have a 80# bloodhound who i am having a problem with pulling himself over a 6 foot wooden fence i like innotek 5100 account of options but not sure if i would need the petsafe stubborn have not seen any reviews on bloodhonds would like to know your opinion

ADMIN – Hi Frank,

The 5100 will will with your bloodhound. Also, combining the 5100 with an existing fence will provide an almost instant solution. You can expect your bloodhound will not be able to climb the fence.

Ray November 13, 2011 at 8:52 am

So far the fence has been working out very well. I have a chainlink fence in part of my yard, so placing the wire on the chainlink fence made it easy to install. I am not happy with the twisted wire, for my small dog, a cocker, got hit. I had to relocate a part of my install. My big old dog still runs through it. I know more training is needed. The cocker trained easly. All in all a good unit with no problems. Only if the collors had an adjustment for small or big dogs. Have not worked with the remote yet.

Keith November 4, 2011 at 11:30 am

Hi, I have a five month old yellow lab, and a 1 yr old chihuahua … wayy little critter.
The little one bolts the minute the door is opened like a bat out of hell… the lab will hang out, but eventually wanders off in search of the little one. I need a fence for both… any suggestions. I was wanting the 5100 and that would shock the crude out of the little one, so probably not a good fit for both.. ??? your thoughts

ADMIN – Hi Keith,

The 5100 is going to be much too big for your chihuahua, it doesn’t work well for dogs under 20lbs. A better choice would be the PetSafe systems that let you mix-and-match collars. Something like the PetSafe Stubborn system (using the included collar for the Labrador and keeping it on the lower settings), and an extra PetSafe Little Dog collar for the Chihuahua.

ible Brad October 31, 2011 at 2:37 am

I’m considering the 5100 and was wondering if the transmitter would interfere with my satellite TV signal or my computers wireless network? Also, were I’m considering running my boundary wire is very close to underground power lines and a buried satellite TV cable, will the power line interrupt the boundary wire signal and will the boundary wire interfere with the TV signal?

ADMIN – Hi Brad,

The wired dog fences use a signal that is similar to an AM radio (approx 600 kilohertz), but much weaker. This is a very different frequency to WIFI (2.4 gigahertz) and Satellite TV (approx 10 gigahertz). The only issue with interference we hear of with modern dog fences is with ham radio operators.

I have a 4. foot wooden fence that my dog jumps /climbs over. What do you recommend as wire placement and range setting? I want to maintain the most usable yard area. I have a 5100 system I am thinking of running the wire along the top of the fence and setting the range at the lowest setting hopefully when the dog places her feet on the fence she will receive a correction. ideas?

ADMIN – Hi Tim,

The decision on where to set the boundary depends on the size of the dog, and whether they are escaping by jumping over clean, or if they have to scramble for a few seconds to get over.

For dogs that are sailing over the fence, you want to set the fence range wide enough so that it triggers around 3 feet before the dog gets to the fence. For dogs that have to do a lot of climbing, you can set the range so it starts later – around 1 foot before the fence.

You can place the wire on the top of the fence and set the range so that it only triggers when the dog is climbing the fence as you suggest. However, that will make the training very difficult. I would suggest you start with a little wider range, and then once the dog is trained you can dial back the range to give the dog more usable yard area.

Two questions –

Is there a training collar/inground fence combination built for a Jack Russel? 12-15 lbs and not very high off the ground.

I see you recommend training on the fence first, and then the collar – most certainly not both at the same time. Would it be feasible to train first on the collar, and then on the fence – not at the same time? He’s got basic obedience training (using a mini – prong collar) and I’d like to work him off leash using the trainer (a sort of continuation of the on leash training) and feel it actually somewhat more important at this time than training the fence (which we couldn’t put in until winter, anyway, so have a couple months to go).


Admin- Hi Dolly,

The Innotek IUC-5100 is the only fence we offer that has the ability for a hand held training remote. We recommend that dogs weigh at least 15 pounds with minimum neck size of 7”. You can train with the hand held remote before training on the containment fence.

Jordan August 20, 2011 at 10:08 pm

Hello we just bought the 5100 and we were wondering with the remote, how do you activate it, the remote does not set off the collar. Also We have a husky and it seems like she does not feel the shock we shaved off a bit under her neck, but how are we sure that it is touching the skin correctly, i saw that there was a skin sensor for 90 seconds after you take it off the charge but it still didnt seem to work. Thank you.

ADMIN – Hi Jordan,

The remote function needs to be activated on the collar in order for it to work. You pair the remote to the collar by holding the remote right next to the collar, pressing the “Dog 1/Dog 2” button until “Collar 1” is shown as active on the remote LCD, then you press the “Tone” button on the remote until the collar beeps. You will know you have done this correctly, because the second light on the collar will turn green. This process is shown in more detail on the Innotek IUC-5100 manual.

Chris August 16, 2011 at 9:06 am

We are about to get a new Lab puppy. What age should we start training for the fence?

ADMIN – Hi Chris,

We like starting a puppy any time after 6 months. The reason for waiting is that older pups tend to have longer attention spans and more developed cognition making the training faster and easier. If you have an advanced pup, you can start them as earlier if they can reliably do a sit, stay, and a come on command.

Anthony August 14, 2011 at 11:41 am

I have a 15lb Jack Russell and a 86lb Lab/Weimaraner, they have about the same temperament but obvious size differences. I am a huge fan of the IUC 5100/4100 for it’s waterproof collar, rechargeable batteries, smaller collar, reliability and it’s ready test collar.

My jack russell is 8 yrs old and was trained by a remote training collar, so she is familiar with boundaries and the beep a collar makes to preempt correction. The other dog is the 2 yrs old and he wants to take off and explore and knows no boundaries. Is it just not gonna work for these two dogs? I wanted to try not to settle but am looking for advise.

ADMIN – Hi Anthony,

You can use the Innotek IUC4100 and IUC5100 with dogs of different sizes, you just need to take an extra step and add a resistor to the smaller dog’s collar so that the correction on that collar is reduced.

See here for more details, see this page on adding the resistor to the Innotek IUC4100/5100. When you place your order, shoot us an email and we can send the resistors out to you (no extra charge).

FYI – I would lean toward using an IUC-4100 collar for the Jack Russell – the IUC-5100 collar will be a little too big for him.

Derrick August 3, 2011 at 4:16 pm

I need to purchase a new electric fence to replace a nonfunctioning “invisible fence” system. We have an area of approximately 7-8 acres already bordered with wire. I am considering the Innotek 5100 but have some concerns re the rechargeable battery after what I have read on other sites. Is this a fault or related to poor charging?
I like the feature of the remote correction but would it be useful in our 7-8 acre field. We would like to train our 1.5 year old to stop barking at everything that moves.

ADMIN – Hi Derrick,

The 5100 and 4100 collars had a bad batch of batteries go out last year. That problem has since been sorted out. (Also note, it did not affect many of our customers, we figured out the issue early and started testing collar batteries before sending them out)

The range on the remote trainer is not anywhere near as good as dedicated units and is not much good for anything but up-close training or around the house training. It gets unreliable after about 10 yards. It will be completely useless over 7 acres. I would recommend you use a dedicated bark collar, or a dedicated long-range remote trainer.

Mark July 16, 2011 at 12:28 pm

Hi There – I just installed the ICU-5100 and when testing the collar, noticed as I approach the boundary (set about 10′ width) the collar will make a warning tone and within a second will then put out a correction, without moving any closer to the wire. Is this normal. Should there be an area at the start of the boundary field that only gives a tone? I called Innotek and they replaced the collar and the new one behaves the same way. Also tried it on a short 40′ loop. Thanks For you time

ADMIN – Hi Mark,

That sounds normal. The Innotek’s have an anti-linger feature to stop dogs hanging out in the warning zone. So if you stay in the warning zone it turns to correction.

As a practical matter, I would not worry about warning zones. Once the dog is trained they don’t need a warning and will keep away from the wire without requiring a warning or reminder.

Bonnie July 14, 2011 at 11:22 pm

Hi there,
I have two Malamutes. One is 10 months and the other is three months. We have 80 acres and live in Canada. I’m looking at the IUC-5100 for both dogs. I noticed that you say this would be a good system for huskies as they are sucks for pain but what do you think for malamutes? I was also considering the stubborn dog. What is the price of your shipping to Alberta Canada? Thanks for your help.

ADMIN – Hi Bonnie,

If you want to cover 80 acres, you’ll need to go with the SportDog SDF 100A and add 8,000 feet of wire. I’d also recommend upgrading to the largest gauge wire you can budget as well. This will lower the risk of breaks. The SportDog fence contains the same collar base as the Stubborn fence collar and even operates identically. Your Malamutes would do well on this fence.

For under 25 acres, the 5100 would also work well. Keep in mind that their thick undercoat presents a contact problem. PetSafe offers special thick fur probes for Husky/Malamutes that you can purchase separately from them. The long fur probe that comes with the 5100 is not sufficient for these dogs.

jay July 13, 2011 at 4:24 pm

I need lightning protection built in to the circuit board, I think. Can you help me?

ADMIN – Hi Jay,

Lightning protection is available through an add-in module on all systems. The add-in module is included in the Innotek IUC-5100 package. For all other systems it is a $39.95 optional extra.

richie July 4, 2011 at 10:53 am

Just rescued a 2 year old shepard huskie mix (59 pounds have to get him to 70). We have 5 other dogs he is getting use to.The only thing is we have 2 cats he goes nuts when he sees them.We put him outside and jumped the 4 foot gate.The whole yard is fenced at 5 feet except the gate.Can we wire the system on the fence and just bury it at the gate?

ADMIN – Hi Richie,

You can indeed run the dog fence wire along an existing physical wire fence and only bury the wire in the section with the gate. This works well, with the physical fence in place the dog usually learns much quicker because there is a clear representation of the boundary.

Amber June 28, 2011 at 10:06 am

We have the innotek 5100 and we had it all set up but now the box is flashing green and red and beeping indicating that the collars are not fully charged but the collars both are blinking green indicating that they are fully charged. We are only using one collar but could they need new batteries?

ADMIN – Hi Amber,

The flashing red & green collar recharge reminder is a ‘dumb’ feature that just reminds you once a month to recharge the collars. It does not actually know if the collars are charged, it simply reminds you once a month. This is useful on older models where the collar has no low battery charge indicator, but should be deactivated on the Innotek IUC-5100 where the collar itself will indicate if it needs charging.

To switch it off, go to the control panel, find the middle switch labeled “recharge reminder” and turn it to the off position. (NOT A or B)

Lorrayne June 10, 2011 at 2:53 pm

Please help… thanks :) I have an American Pit Bull that weights approximately 65-75lbs and my friend’s dog that will be staying in my house during the day is a some type of mix shepherd and he is probably about 45-55 lbs. I was thinking of purchasing 5100 but i am not sure if it would work with my Pit. Although my Pit is supper sweet and submissive to any anyone, he is extremely strong/powerful and he has “selective” hearing. Now My friend’s dog, he is a completely different from my dog. He is extremely hipper, fast, and extremely dominant with come with a bit of aggression. Luckily my pit is submissive, but her dog constantly attacks my dog or any other dog. But the questions are: Does the 5100 will have enough power to restrain my pit from taking off? Can we buy a separate collar that comes with a remote control so both them can be controlled in different setting but using the same system? Plus it would be great for us to be able to train them outside of the property individually with our own remote. Thank you, Ld

ADMIN – Hi Lorrayne,

Shepherd and Pit Bulls can sometimes require a lot of correction due to breeding for low sensitivity to pain. It is hard to say without working with the dog, but a good clue is if you have accidntly stood on the dog’s tail or seen him run into something. If the dog was nonchalant or stoic, it is a good clue they are likely to require a high correction.

With the pair of dogs you have, I think you would both be better off with a PetSafe Stubborn. You may not need all those extra correction levels, but if you need them they will be available. Also the ability to alter the correction level on each dog separately is going to be useful if it turns out one dog reacts very differently from the other which is very possible in your case.

The Stubborn does not have a remote trainer, but with the price difference you should be able to get a couple of separate basic remote trainers for the dogs.

Andy June 7, 2011 at 9:59 am

Hey all, great website. TONS of great information!

Just a quick question: I am having a tough time figuring out my layout. I am wanting to keep my dog in the backyard only, and need a way for her to go out the back door, necessitating some sort of break in the system. I’d really rather not send the wire back in the loop around the yard, to maximize her space to run, and sending the wire up near the gutter is going to be quite difficult. Is it possible to do a twisted wire the length of the opening, then send a single wire back in the opposite direction against it to start the loop? I hope this written version makes sense. Thanks!

ADMI – Hi Andy,

Thanks for the compliment.

Running a triple wire (a twisted wire, then doubling back with a single wire) will result in a section of active field. I am afraid for a backyard only layout, you either have to go (1) up and over, (2) double back on yourself to make a U-shaped loop, or (3) loop tight around the front of the house. (See this link for diagrams of the most common backyard dog fence layouts) Nothing else works very well. I find going up through the guttering the easiest way to do it.

PAULA June 6, 2011 at 10:37 pm

I’ve done my homework on researching all the available in ground fencing systems; I think the I U 4100 is going to be my best bet. We have two 1 year old litter mates, about 60 lb. lab mixes. The male has a long full hair (like a springer spaniel) and the female got the short lab coat. Will they feel the shock the same or will she get too much and him too little?
Also, we are moving soon to a new house without a fenced yard. (Our current house has a wooden 3 rail fence with animal wire stapled to it.) Should we set up the I U 4100 in our current yard with the fence so they will be trained when we move? It makes sense, but I might be dead wrong. I definitely need advise on this. Thanks!

ADMIN – Hi Paula,

Both dogs will feel the correction the same. With the long hair dog you will use the (included) long probes, with the short hair you will use the short probes.

With both dogs you need to get the probes actually touching skin – hence the equal correction. The 4100/5100 both have a built in detector that lets you know if you are getting contact and is very useful.

Training them now will give them a head start when it comes to training them in the new house. But, if you are busy (with the move!) it is fine to just train them in the new place. With labs, I would not expect any problems.

Julie June 5, 2011 at 7:58 pm

Is the Innotek 5100 the only system w/ the remote control option in addition to the fence? We are not training our Choc Lab for hunting, but are thinking of using the remote option for occasions when we are away from our home, (like at our parents’ home or at a park letting the dog run), or for when the dog gets loose & heads for the highway 1/8 mile from our home (which he’s survived once before…miraculously). Are these good uses for the remote control, recognizing that it would have to be in “training” mode and thus would run the battery down faster, or do you see potential problems in these situations? Otherwise we were leaning toward the Sport Dog or Pet Safe brands due to greater flexibility in levels of correction. Your thoughts on the best system for our “runner” of a lab would be greatly appreciated!

ADMIN – Hi Julie,

The Innotek IUC-5100 and the Innotek SD-3000 are the only ones with remote correction built into the system. The SD-3000 is a really old system with no adjustable correction levels and a weak collar. The IUC-5100 is by far the better choice.

The remote trainer is decent for everyday around the house obedience training (sit, stay, etc). It is no good for field work, so once the dog is more than 100 feet away it gets very spotty. So, I would not rely on it for training a dog to come when off-leash at say the dog park.

With a lab, you should have great results with either the SportDog or the Innotek. They are both good systems and labs are easy to train.

Walter Jeffries June 3, 2011 at 3:41 pm

We have about 70 acres of pasture we would like to setup with a in-ground fence system as sometimes our livestock guardian and herding dogs will go out for walk-abouts. I like the remote beep on the 5100.

I am considering setting the fence up for a subset of the 70 acres, an inner area where the problem walk-about dogs would have to stay within. The specifications list 25 acres for the fenced area and also 5,000′ for the wire length. A 25 acre area could be 10,400′ (1 acre wide x 25 acres long). How hard and fast is the wire length issue? Could I go up to 6,500′?

You mention hanging the wire from above ground fence lines with zipties and also you mention an issue of running along the electric fencing. We use high tensile electrified smooth wire around the perimeter and for the paddock subdivisions. Can you elaborate on this more. I would like to hang the wire (burial is not possible on our rocky mountain soil) but the fences are everywhere. Many thanks for all the help.

-Walter (Sugar Mountain Farm)

ADMIN – Hi Walter,

I would avoid running any of the systems near the stated maximum capacity. When you run them near the maximum, you can often get very thin boundaries (around 3 feet wide).

The acreage specification is based on a square or near square layout and would not apply to a really long & think lot. The maximum amount of wire is going to be around 5,000 feet. If you go to 6,500 feet, I would expect that the boundary signal would be weak and ineffective, maybe triggering only 2-3 feet from the boundary wire which is going to make training difficult. I would rather see you get some higher capacity system like the SportDog SDF-100, where you can do 10,000 feet. That way you will have good strong signals all around the boundary.

You can indeed hang the wire along your electric fencing. We just attach the wire to the existing poles using zipties. You don’t need to use special insulating mounts like you do with electric fence wire. (Note, you occasionally get interference from some electric fence systems – so you want to string up a small section and test it first before doing the full perimeter)

Stacy Gael June 2, 2011 at 10:18 pm

I just got the 4100. I’ve seen other comments about attaching the boundary wire to a chain link fence. I just want to be certain there is no issue with running part of the fence at ground level, and then other areas along the top of the chain link fence. One side of my yard has a wooden fence and this section would be installed with landscape staples. Thanks.

ADMIN – Hi Stacy,

There is no issue with running the dog fence wire at ground level for some of the installation and other parts at the top. But, you will need to crank up the boundary width so that the signal reaches the ground even when the wire is elevated. This will mean you have have wider boundaries at the places where the wire is at ground level and narrower boundaries where the wire is at elevation.

If you are going to run some wire at ground level, it would be better off running it all at ground level. But, if that is not a possibility, the setup you described would work.

Lacinda June 2, 2011 at 9:09 pm

I have a 1.5 year Border Collie that has found a way under our existing fence. I was thinking about putting in a wired system to deter her from getting anywhere near the fence. She moves fast so am not sure what type of system I should get. What is the difference between the Stubborn dog and the URC4100/5100. I don’t think I need the remote as I don’t plan on doing any further remote training. She is too smart and too quick. At this time she weighs about 40lbs.

ADMIN – Hi Lacinda,

With a fence in place, it should be particularly easy. The Innotek IUC-5100 is basically the same as the 4100 with the addition of the remote trainer, so if you don’t need it the IUC-4100 is the way to go.

As to the difference between the 4100 and the PetSafe Stubborn Dog Fence. The IUC-4100 is a smaller collar and the collar can be recharged. It also has an electronic collar-fit feature which is useful in long hair dogs to make sure the collar is on correctly. The Stubborn collar is about double the size and uses a disposable 9 volt battery (that lasts about 3 months). It also has a very strong correction, but can be turned down for more corrected dogs like Collies. The Stubborn is also about $100 cheaper.

Both are good systems and would be a good choice for a Collie.

Warren June 2, 2011 at 2:22 am

I just purchased the 5100 and am planning on making the containment loop for the back yard only, with the house becoming one of the borders. In order for the dog to have access right up to the house, I was planning on running a leg of the loop inside my house. Would there be any problem with house wiring, plumbing or heat ducting interfering. I can’t do the loop-back system as shown in the instructions for this type of setup, nor do I want to encompass the entire house within the loop.

ADMIN – Hi Warren,

Avoid running the wire alongside household wiring. Sometimes the dog fence signal can get induced in this household wiring, then everywhere the wiring runs can act like it is boundary wire. This leads to things like power outlets trigger the dog fence collar.

Another alternative for a backyard only installation is to run the wire up and over the house. You run the wire up a downspout, along the gutter and down the downspout on the other side. The vertical elevation of the wire allows the dog to go underneath and enter the house without getting the correction.

Check out our installation (planning) pages for more ideas on backyard only layouts.

Kathy May 31, 2011 at 6:09 pm

Are the collars adjustable for most dogs? Are there any collars (besides the systems specially for small dogs) which would not fit a Doberman?

ADMIN – Hi Kathy,

What is the neck size of your doberman? We would be happy to send you a list of collars that would work.

The collar size for most of the collars is listed on the “specs” tab. For the Innotek IUC-5100, the maximum collar size is 32 inches.

Blake May 30, 2011 at 5:53 pm

Hi Stu

I am going to buy the IUC 5100. I have about 3 acres to cover which will require extra wire. I have a couple questions.

1. I am in Panama and am going to order this week and bring back on June 9th on airplane so I need to minimize weight. Is the 20 Gauge wire a typical insulated stranded wire(similar for household or automobile uses?)

2. Can the wire be mounted on a barbwire fence along the bottom strand of wire, versus in the ground? Will the barbed wire interfere?

Thanks and looking forward to hearing from you.

ADMIN – Hi Blake,

Here’s what you’ll need to look for when buying your own wire:

  • Copper wire, with an insulating jacket
  • Rated at least 600v
  • The jacket is rated for direct burial. e.g. high density polyethylene jacket.

You can mix solid or stranded copper, but make sure you use the same gauge throughout your installation.

Avoid using housing wire, it tends to be PVC coated and rots out particularly in acid soils. You can still use it if nothing else is available and it will work fine, just be aware you may need to replace it every 5 years or so.

The wire can indeed be mounted on a barbed wire fence along one of the wire strands. There will not be any interference from the barbed wire fence. (Sheet metal is what can cause amplification issues)

Mary May 24, 2011 at 6:58 am

Will the Innotek collar, IUC-4225, work with the 5100 fence just for containment? We need to buy an extra collar, but we do not need the remote training feature on it. Thanks! Mary

ADMIN – Hi Mary,

The collar from the Innotek IUC-4100 (the IUC-4225) will indeed work with Innotek IUC-5100 fence. As you mentioned, the only difference is the IUC-4225 collar will not work with the remote control, only the fence.

Denny May 12, 2011 at 8:17 pm

I have a German Shorthaired pointer and she’s nearing 4 months old. She’s had “sit” “down” and “whoa” (hunting term for stop where you are, I also use it as others would use “stay”) she does these and has been doing them since 8 weeks however she’s not that great with “come” yet as she tends to ignore you unless you have something of interest to her. I am interested in the 4100 for the slimmer collar but like the 5100 because of the remote. She is a high energy breed although she is on the milder side, I’ve seen labs worse than her. Anyway, my question is if I got the 5100, can I buy the slimmer collar only from the 4100 separately to use as everyday use and put the 5100 collar on her for outings off my property and use for corrections such as digging/surfing. Are the 2 collars compatible with the same base unit? Or should I get the 4100 and find a stand alone remote collar. If so which one? I appreciate the help! Your q&a is awesome and you seem very insightful!

ADMIN – Hi Denny,

Hunting dogs are usually ready for the dog fence training much before regular pet dog, because you guys do a great job working with them from a young age. From your description, you could start working with her now.

With a German Shorthair, even a pup, the larger collar size of the 5100 would be a non-issue, so I would not get both collars. Just one will be fine.

I would also consider getting just the 4100 and getting a separate remote trainer. The remote trainer on the 5100 is fine for very basic around the home obedience. But if you are doing any field work it will completely inadequate. Even a mid-range remote trainer will outperform the 5100.

Our customers always highly recommend the tritronics training collars for field work.

Steve May 11, 2011 at 10:32 am

Hello, our recently purchased Innotek 5100 is acting erratically. The field width varies at different times (going from ~2′ to ~15′), even in the same spot with the same transmitter settings. In other parts of the yard there is no field near the wire, but a field exists far inside the safe zone (like it is skipping). Finally, the collar immediately corrects in many spots (no warning tone), and often continues to correct as we back away from the wire.

Diggers hotline marked all power and comm wires, as well as gas and water utilities. We are not running parallel to any, and cross them at right angles. We performed a short loop test. It worked fine with about 15′ of wire, and the field changed widths as we moved from 9 o’clock (about 3′-4′)to 12 o’clock (5′ – 6′). There did not appear to be any change in field width as the setting changed between 12 o’clock and 6 o’clock.

Our neighbor has a dog fence, which we turned off for some of our tests. We also moved the wire all over the yard (up to 20` movement) and set it in in different configurations. Same results. A call to Innotek tech support did not provide any additional suggestions.

We thought about trading for a Perimeter Ultra, but given that the neighbor’s fence was turned off with similar results makes me wonder if a different frequency would help.

Your thoughts? Thanks for your help.

ADMIN – Hi Steve,

The symptoms you are describing are the classic symptoms of the boundary width being set too wide. The boundary width dial is very sensitive, and when you set it to say six o’clock, with a smaller installation like yours (from your order it looked like you only used 500 feet of wire), the boundary width will be 20+ feet. Often it will blanket the entire area and the opposite sides of the fence will start interfering with each other. This creates weird interference patterns where you get pockets of correction and non-correction and a moving boundary line.

I would turn off the neighbors fence (so we can eliminate that as the problem, interference with the neighbors fence causes similar symptoms). Then turn your boundary dial as far as it will go toward minimum. And make sure the property size switch is set to “small.” Then go out and test the fence with the collar. You should get no triggering of the collar.

Next, go back to the control box and turn the boundary width dial up a 1/12th of a turn. Again go test the fence with the collar. Keep repeating this process until you have a boundary that starts triggering the collar at 3-5 feet from the wire. The boundary dial is very sensitive on the IUC-5100/IUC-4100 so you only need to make very small turns to get large changes in the boundary width.

There are other possibilities, but this seems like the most likely. Give it a shot and if that doesn’t work then we can try a couple of other things.

The problems you describe don’t sound like any issue with buried utilities. If there is an issue with that, the problem tends to be very local, and may affect one boundary but not all boundaries.

If you give us a call, we are happy to talk you through it live.

Adam May 9, 2011 at 9:12 am

Will a 4100 collar work with a 5100 system? I like the 5100 system, but are concerned about the bigger collar. I have 2 dogs – one will be fine with the 5100 collar, but the other may be on the borderline for size/weight (~17 lbs), and therefore I’m wondering whether I can sacrifice the remote control capability for her and use the smaller collar. Thanks!

ADMIN – Hi Adam,

You can indeed use the Innotek IUC-4100 collar with the 5100 system and vice-versa. As you mention, the 4100 collar does not work with the 5100 remote control, but it does work with the containment system. For a 17lb dog, the 4100 collar will be a more comfortable fit.

Dan April 28, 2011 at 3:50 pm

We are getting a male chocolate lab who is 1 1/2 yrs old and approx. 80 pounds. He has already been trained on an underground fence system by the previous owners…(which brand I currently do not know, but could find out if necessary). I want to have the yard ready when we get him home. Do you think I should get the same system he has already been trained on? Will it be hard to train him to his new surroundings? Is there a way to keep him out of the pond which is in the middle of the back yard? What system would be best for us? We have 7.5 acres that I could fence in, but we really only use about 3.5 which is all grass, the back 4 or so acres is all field. Thank you so much in advance for your help!

ADMIN – Hi Dan,

Getting the same fence will provide your dog with familiarity, so that may be a good idea. If you utilize the training flags, training should not be difficult. Dogs remember the flags and understand what they mean and what to do. (That’s if they were trained well before.) You create an interior exclusion zone around you pond and connect it to the main boundary loop. Here’s an illustration to give you an idea: If you’re looking at all the fences, the Innotek 4100 will work well for your chocolate lab. This fence has a max capacity of 25 acres. You’ll need to bundle in an additional 1,500 feet of wire to cover 3.5 acres.

I have a chihuahua and a maltipoo. I like the rechargeable collar and we are wanting to wire a larger lot. What would be the best system for me?

ADMIN – Hi Lori,

With two dogs of that size (I presume they are both under 12lbs), I would opt for the PetSafe Little Dog. It is the only system where the collar is small enough for that sized dog, and where the correction level is lower enough for those dogs. It is unfortunately not rechargeable, and to add insult to injury uses a proprietary petsafe battery. But, for dogs of that size, it is the only system that we would use.

i have an 18lb cavachon. and was looking at the 4100 but now thinking it may be better to get the 5100 since it seem like a better deal. he is 11 months old and eats everything in site so i thought it may be good to have the remote to correct him when i see him getting into something he should not. my concern is the size of the collar for him. i also am somewhat concerned with the life of the collar as well. i have read there have been some real problems with these. i your recent experience has there been an unusual amount of complaints or has the defect been corrected? thanks for your help..

ADMIN – Hi Louise,

The 5100 is a great deal considering everything that’s bundled in. You’re right the collar may be slightly big on your Cavachon, but since he’s so close the minimum weight limit I think it worth a try. Simply put the collar on him when you get the fence without installing it or turning on the collar. If it’s too large, we can exchange it out for the 4100 fence if it’s too large. However, in doing so, you’d lose the extras from the 5100.

I can’t speak for the whole industry, but the majority of our customer’s collars last well over 5 years. Remember that the Lithium Ion battery in the collar has a certain charge life so it will go bad eventually anyway. The collars are covered under a manufactures warranty, so in 5 years when you have a collar no longer holding a charge, you can contact Innotek and get a new collar for the discounted cost of around 35 dollars plus shipping.

Susan April 18, 2011 at 12:39 pm

We recently were given the IUC-5100 by a friend who only used the collar — the rest of the system is still unpacked. I tried charging the collar on the charger (on a working outlet) & found that, while on the charger, the collar lights flashed red well beyond the time it should’ve taken to fully charge. There were no lights on the collar when off the charger. I let him know we had a problem with the collar, so he gave us an additional collar he had to try. It’s doing the same thing, so far. Could it be the charger? I’ve thoroughly cleaned all of the contacts on both collars & the charger, but it hasn’t helped. If these collars have been sitting around uncharged for over a year, have they gone bad & what can I do to get them working without replacing the collar?


ADMIN – Hi Susan,

Innotek recommends that collars never go more than 6 weeks uncharged. If they’ve been sitting for an extended amount of time, they may have become defective. The best thing you can do is see if you can get an original receipt from your friend which will allow you to contact Innotek directly using the limited lifetime warranty covering the system and collars.

Otherwise, the only thing you can do is purchase new collars.

Dave G. April 15, 2011 at 3:14 pm

We just rescued a Lab mix and are going to put an in-ground fence around our 1.3 acre lot. I’ve looked at the PetSafe and Innotek systems and am most interested in the 5100 system (remote trainer and twisted wire a plus). Here’s my question … we have family members that have PetSafe in-ground fences for their dogs; if we want them to be able to “play” in each other’s yards do we need to go with PetSafe as well or has PetSafe/Innotek made it possible for the collars to work with either system?

ADMIN – Hi Dave,

Unfortunately, the 4100/5100 is not compatible with the PetSafe in-ground wired fences. You will need to go with one of the PetSafe systems in order to get the compatibility you seek.

Dave April 14, 2011 at 11:02 am

We live in a rural setting and want to keep the dogs away from the road. We are looking at a single-sided boundary loop along the length of the road (about 1500′). Our driveway comes out in the middle of this line, and we have a cattle guard to keep livestock in their place. Will the metal of the cattle guard interfere in any way with the operation of the fence or should we go around it? If we go around, how far from the cattle guard should we bury the wire?

ADMIN – Hi Dave,

The cattle guard may not be an issue at all. It may amply the signal, but it will most likely not cause any issues.

Susan April 6, 2011 at 12:36 pm

In reading a few of the answered questions, I understand that you discourage using the remote trainer while training the dog on the fence, which makes complete sense. I am wondering, however, if the remote trainer could be to correct our dog soley inside our home until he is fully trained outside on the fence? Would it serve well to correct barking & aggressive mouthing? Thank you so much; for covering all the bases in your forum!

Admin- Hi Susan,

We do not recommend using the remote trainer anytime throughout the training of your dog with the boundary fence. For example, if you are outside training the dog on the new boundaries and he/she is receiving warning and corrections. When the dog goes into the house and starts to receive the same warnings and corrections, this could be very confusing. You will both be much happier if you wait until the outdoor training is completely finished before starting on the indoor.

Tom April 2, 2011 at 10:01 pm

i have 2 dogs which are both over 80 lbs. I am going to need 2 collars and one of my dogs would do better with the trainer collar. If i purchase a innotek 5100 system will the 4100 collar work with this system just for the containment?

Admin-Hi Tom,

Absolutely, the Innotek 4100 collar is compatible with the Innotek 5100 containment fence.

Katri April 2, 2011 at 7:39 pm

We are looking at the Innotek IUC 5100.
Question 1….the remote corrector….is that for correction when you are OFF property?
Question 2: When taking our dog for a walk, how would we get him off the property with the collar on…but then wanting the remote on him for being off leash? That is if the collar is in fact a remote corrector.
Hope my questions make sense!

ADMIN – Hi Katri,

1. You can use the remote correction for both correction on the property (i.e. withing the containment zone) and off the property (i.e. outside the containment zone). The remote is completely independent of the electronic containment fence.

2. To get the dog past the boundary, you could either remove the collar until you are past the correction zone, or you could switch off the fence at the base station.

Brad March 26, 2011 at 10:42 pm

Will the 5100 collar be too large for a 20 lb daschund? Or should I get the 4100. It seems like you get more for your money with the 5100. Thanks!

Admin- Hi Brad,

Your Daschund should work perfectly with the either system. The collar on the 5100 is about 50% bigger than the 4100 collar, but would are fine on dogs 20lbs or over. So if you like the extra incentives that the Innotek 5100 offers, I would go with it.

Jay March 22, 2011 at 5:51 pm

I am considering the 5100. I am buying this fence ahead of my move to a new home. I wanted to use the collar to do other training of a 2 yr old Golden Retreiver. Am I putting the cart in front of the horse? I will be moving to my new home in June.


Admin-Hi Jay,

Though we cannot provide support for training with the remote trainer, we do not recommend using both the fence and the remote during fence training. Using the fence and remote at the same time could be confusing for the dog. As long as you do not use the fence and remote simultaneously, you’re dog will be okay.

Dan Hogan March 18, 2011 at 1:46 pm

I have the 5100 system. It worked well for about 2 years. My newest dog was using the collar when its battery stopped taking a charge before the training was done. I ordered a replacement collar. It works with the fence wire, but it doesn’t respond to the remote training transmitter. Would the transmitter go bad as well, or could the collar be a slightly different frequency that doesn’t work with the transmitter?

Admin- Hi Dan,

There are few things to try to see if the remote trainer is working. First make sure you have an Innotek 5100 collar. The Inntek 5100 remote trainer in not compatible with a different collar. To see if your collar is the 5100 collars, look on the top base to the right of the Innotek label. There should be a little remote logo. Second, make sure you have the collar synced with the remote trainer. To do this, simply turn the training mode of the collar, hold the collar within 1 inch of the remote antenna, taking care not to touch the skin contact points. Press “Dog1/Dog 2” button once or twice until collar 1 shows as active. Press the TONE button, also labeled “1/0”. The collar will emit a start-up tone, and the right-hand light will glow solid green.

The Innotek 5100 only has one frequency.

Lance March 9, 2011 at 6:31 pm

I was wondering if the IUC-4100 collar is adaptable to the IUC-5100 system. We have one dog over 50 lbs. and two other dogs under 20 LBS. Your site indicates not using the 5100 system for the smaller dogs due to the increased size of the 5100 collars. I like the remote feature of the 5100 system for my Huskey, but wanted to purchase the 4100 system collars for the smaller dogs .if it is compatibable.

Admin- Hi Lance,

Yes the collars for the Innotek 4100 will work with the 5100 system. The only downside of the Innotek 4100 and the Innotek 5100 systems is that you cannot adjust the correction level of each collar separately. There is a workaround that involves running a resistor across the probes of the collar to reduce the correction level on a collar. If you decided to use the workaround method, than the Innotek 5100 with two extra 4100 collars would work wonderfully for your three dogs.

For more detail on the workaround please see our instructional video at (

Eric March 8, 2011 at 5:20 pm

I have a 6 yr old 55 lb husky. I want to contain her at home, but also take her out hiking with us. The IUC-5100 seems to be a good match for home containment and providing feedback while away from home. Are there any drawbacks I need to consider? Also, just for clarification, how many correction levels are available. The kit info references 10 different settings for the remote trainer, the reference table indicates 3 different correction levels, and another website references 7 levels of stimulation for the IUC-5100. Thanks.

ADMIN – Hi Eric,

The 5100 would be a good choice for a Husky. The collar-fit feature is very useful when trying to fit a collar on a dog with a thick coat like a Husky.

The collar has three correction levels for the dog fence function (plus each of these levels is progressive, meaning the close the dog gets to crossing the boundary, the higher the correction gets). The collar has ten correction levels when used as a remote trainer.

tanya March 5, 2011 at 9:38 pm

I was wondering when the rechargeable collar battery dies if you had to buy a new collar or if you could just get a new battery? I was told by someone selling another brand that the reschargeable collars had to be replaced when they don’t hold a charge anymore.

ADMIN – Hi Tanya,

You will only be recharging the battery monthly, so you tend to get a lot of life out of them. Then oldest collars are around six years old now and have just under half the original life, so I would expect you to start needing to replace the battery around years 5-10. Replacement cannot be done at home, only through the factory and costs around $35.

Misha February 24, 2011 at 8:26 pm

I was ready to purchase IUC4100 from you and install it my self as soon as snow leaves Ohio. We own 5 months old Doberman Pinchner and our house is on 1/2 acre development lot. Dog is listening very well to my commands but not my wifes – bitting, jumping and not responding on “come”. Someone mentioned purchashing training collar so she can use it and I connected it with IUC5100 instead purchasing separate training collar. With adding $40 for IUC5100 I can have lighting module and remote – just separate Pet Safe Deluxe PDBDT-305 I was looking for cost about $86.
Am I thinking in right direction? Is IUC5100 remote training comparable to separate training collars? Is different training collar better solution so dog can make different from fence correction (less confusion) – if there is anything different (sound may be)?

ADMIN – Hi Misha,

The 5100 is indeed a good deal, for $40 you get no only the remote trainer, but also the lightning protection, and also the twisted wire. But, it would be misleading to compare the 5100 remote training collar to the dedicated remote training collars. The 5100 is really only for short range use when the dog is within 20 yards, so is good for training around the house – but not useful for ‘come’ training. It is not very good once you get beyond 20 feet, while most dedicated remote trainers have a range of at least 100 yards and some go even up to 1 mile. The dedicated units are also much more consistent. I prefer our customers to use dedicated remote trainers, but if price is an issue – the 5100 remote trainer is worth a shot particularly if your needs are modest.

When using a remote trainer and a dog fence, confusion can be an issue. We advise that you do not introduce both at the same time. Instead, start with one (preferably the dog containment system) and let the dog get comfortable with the system before adding the second. Usually dogs that have learned one, tend to pick up the other faster.

Dan Norton February 24, 2011 at 11:26 am

What are max/min operating temperatures for the main transmitter unit? I live in the Northeast so the inside of my garage still can get quite cold?

ADMIN – Hi Dan,

Innotek, the manufacture, states there are no limits in terms of temperature, however, the transmitter will need to be keep safe from both wind and rain.

Terry February 21, 2011 at 4:14 pm

Hi again, thanks for the quick and helpful response! I successfully installed the IUC-5100 and fully charged the collar. Everything was working great for a few days and then we noticed it stopped working. I’m currently recharging the collar, but could it possibly have gone dead in less than a week? This seems to be the only possibility as I haven’t even buried the wire yet and there are no breaks…plus I have the solid green light on the box. Thanks again, great site!

Admin – Hi Terry

We estimate the the charge on the collars to be 2 to 3 days, so yes, more than that would mean that the collars would need to be recharged. I hope that helps you.

Terry February 17, 2011 at 1:33 pm

Is there any instruction on installing the lighting protection included with 5100 available on the site?

ADMIN – Hi Terry,

Yes, we have the video where we show how the lightning protector is installed. It is very simple, you just plug it into an electrical outlet with a ground terminal and run the two boundary wires into the lightning protection, then you run two wires from the lightning protector to the control box. You can also find instruction for installing the lightning protection in the IUC-5100 instruction manual which we have available here on this page under the “manual” tab.

Brian February 12, 2011 at 5:04 pm

I installed the Innotek 5100 system about 3 years ago. Since installation, the line has broken 4 times. I have repaired the breaks with relatively no problems. However, the last breaks occurred at the same time. My lab dug up and chewed through the cancelling twisted wire to the loop. Then she dug up and chewed through the loop on the opposite side of the yard. I repaired with different wire this time (but verified the wire was 20 gauge). The transmitter shows a green light signalling no breaks. The collars are charged and appear to be working. However, when I walk past the line, the collars are not signalled by the underground wire. Am I missing something? Is there something more I need to repair?

Admin – Hi Brian

If your Lab is consistently digging up the section of twisted wire, you may want to run that section through thin wall PVC to prevent the damage.
The wire used for repairs needs to be specific. Direct Burial, Solid Copper, At least 600v made of high density polyethylene jacket. If not, could explain the completed loop with no signal. Go through the “finding a break” process again. See if that helps you.

Josh P February 12, 2011 at 2:13 pm


It is my understanding that the 5100 Contain ‘N’ Train is is now only being produced my PetSafe and not Innotek, is this true? If this is the case, then would there be any issues with fixing repairs/ replacing parts of an Innotek IUK – 5100 system in the future? Thank You

Admin – Hi Josh

No, not at all. The parent company has changed, not the product. As they go through changes, the products will be supported.

Thomas January 14, 2011 at 6:28 pm

I have a concrete 3 rail fence with 2″x4″ wire mesh on it. The fence is ~4′ high. One of my shepards is jumping the fence. I have several questions:
1. If i run the system along the top of the fence is it okay if i is in contact/interwoven with the top of the 2″x4″ wire mesh? Does the wire wear out or break easier if it is not burried?
2. I would like the dog to be able to get close to the fence since the main bathroom areas are in the rocks along the fence. How close would the dog be able to get if the wire is along the top of the fence?
3. Can the twisted (non correcting) wire be within the fence run. I would consider using this by the gate (which is taller) to allow for safe passage.
4. If I loop the correcting line back on it’s self does it double the range, negate the effect or have no effect.

Thank you.

ADMIN – Hi Thomas,

1. The wire can happily live on the top of the fence. It holds up well to the weather and does not need to be buried. Burial is really only needed to protect wire from the lawnmower. Contact with the wire mesh is fine, the boundary wire is insulated and is not affected by contact.

2. It is completely up to you how close the dog can get but the rocks probably aren’t going to be a practical place to toilet if you install a fence. You can set this distance using a dial on the base station of the IUC-5100. As a practical matter you will want to stop him at least 2-3 feet from the fence especially when you are starting the training. Any smaller distance and the training is difficult. The dog would not want to go anywhere close to the boundary line and it is unlikely they would keep using that spot to urinate.

3. No. The twisted boundary wire cannot be within the fence run. To allow the dog thought the gate, you will either need to run the wire high enough above the ground that the dog can pass under without the signal reaching them on ground level. Or you will need to take the collar off the dog before letting them through the gate.

4. If you loop the wire back on itself without any separation between the two wire the two signals will cancel each other out and the range will drop severely.

Debbie January 12, 2011 at 3:35 pm

I purchased the Innotek 5100 a few years ago for my 100 lb. Doberman. It has worked great and I love the training remote as I can take it anywhere I take my dog. Here’s the problem, we recently got a new dog……a 11 lb Chihuahua, she listens very well but I would feel more secure if we could use a bountry collar on her also as our neighbors have two very powerful dogs that I would not want her to get within reach of. Is there ANY collar, (yours or another) that would work with the 5100 system for our little new friend? Thank you. Debbie

ADMIN – Hi Debbie,

For a 11lb Chihuahua, you could use an Innotek IUC-4100 collar. It is about 50% smaller than the 5100 and is compatible with the IUC-5100 system. We usually use the 4100 collars for dogs over 12lbs, but you are pretty close to that borderline. You would also want to use a resistor to reduce the correction level on the collar – the chihuahua would probably only need 25% of the correction of the Doberman. If you give us a call, or send an email with your order number, we can send that resistor out to you with your order.

DON January 4, 2011 at 6:27 pm

I have been reading many reviews online. have the corrections been made with both the Iuc 4100 and 5100 in regards to the collar re-charge problems.

ADMIN – Hi Don,

There were some problems with the Innotek IUC-4100 and IUC-5100 collar failing to charge that occurred in mid-2010. Apparently something went wrong with the manufacturing process and the batteries were not working. They would fail as soon as you put them on the charger. The problem was fixed by late 2010. It was particularly problematic because when the manufacturer went to fix the problem, they no longer had any collars left to send out for warranty claims to people who had bought collars that failed. As you would expect, many people were very upset at the thought of having invested a lot of time and money, then being told to wait up to six months for a replacement collar.

For what it is worth, we largely insulated our customers from any problems. We figured out very early something was systemically wrong, and started testing systems before sending them out so that customers did not get defective batteries. For our customers that got bad collar and got stuck on the long waitlist for a replacement, we at our own expense switched out their collars from our own inventory so that they would not have to wait months to go through the official warranty process. To the best of my knowledge no other retailer did either of these things for their customers.

Sorry, don’t mean to be salesy, but I am very happy/proud with the way we handled the issue and need to brag.

Jon December 24, 2010 at 11:43 am

We live on a farm of 100 acres, but part is also on a busy road. Can we use one of these systems for just the road area? We just got a male lab last week and want to keep him from the road, but have the freedom to roam the rest of the farm. Is there anything you can recommend? We also have a pond, are any of these water proof? Thanks!

ADMIN – Hi John,

If you want to block off just a long section, the best way to do it is to make a long skinny loop that goes along the road. You will need to make the opposing sides of the loop at least six feet apart. For more details, take a look at the diagrams in our Installation–>Planning pages.

The collars for the Innotek IUC-5100 are indeed waterproof.

Rhys December 18, 2010 at 7:03 pm

I already have a wooden fence. Lately, digging has been a problem and I am considering an electric fence. For ease of installation, can I attach the wires to the fence or do should they be buried? I have two large coonhounds( about 70lbs) and their noses seem to lead to trouble. What system do you recommend?

ADMIN – Hi Rhys,

You can indeed attach the wire to a fence without burying the wire. I would recommend fixing the wire at least a few inches above ground to avoid it getting cut by an errant weed eater.

For coonhounds the Innotek IUC-4100 or IUC-5100 works well. Another good slightly cheaper option is the SportDog SDF-100A.

chris November 28, 2010 at 3:31 pm

What are the virtues of the twisted wire that come with the 5100, and if it is so good, why only 100 feet of it. What exactly is the lightening protection and how would it benefit owners? Thanks.

ADMIN – Hi Chris,

The twisted wire is two regular wires twisted together. You use it to connect the control unit to the start of the boundary loop. The twisting wire cancels the signal so that the dog gets no correction when walking over the twisted section. For most people 100 feet of twisted wire is about all they need, because the wire only needs to go from the control unit to the nearest point on your boundary loop. For more details see the Twisted Wire page in the Installation section of the website.

The lightning protection module is a little box that protects the control unit in the event the boundary wire is struck by lightning. When lightning strikes near the boundary wire, it travel back through the wire and knocks out the control unit. The lightning protection module acts like a fuse and stops this happening.

Sam Rogers November 24, 2010 at 11:24 pm

Will the innotek and petsafe collars work together? I have used petsafe for years but am tired of replacing the control units. I do like the ability of adjusting the collar shock as in the stubborn dog that pet safe has. I was just wondering since they are all made by the same people if the collars were universal?

ADMIN – Hi Sam,

Unfortunately, the PetSafe Collars are not compatible with the Innotek. The Innotek IUC-4100; IUC-5100; and SD-2100 collars can all be used on the same dog fence systems. (but note that the SD-2100 collars do not work with the Indoor zones)
