Innotek IUC-5100 Overview

Summary: Dog Fence + Remote Trainer (Discontinued – Out Of Stock)

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.

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.

Tim O'Neill September 23, 2011 at 1:45 am

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.

Dolly September 8, 2011 at 1:01 pm

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.

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: http://www.dogfencediy.com/installation/plan/#exclusion. 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.

Lori April 26, 2011 at 3:33 pm

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.

louise April 20, 2011 at 12:36 pm

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 (http://www.dogfencediy.com/reviews/innotek-ultrasmart-iuc-4100/resistor-hack/).

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.

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. http://www.dogfencediy.com/maintenance/finding-break/

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)

Beth November 24, 2010 at 6:09 pm

Hi – I’m interested in the IUC 5100 but need two collars. Can a single collar be purchased? If so, for how much?

ADMIN – Hi Beth,
You can get extra collars for the Innotek IUC-5100 in our store. When you click “add to cart” it gives you a chance to configure the system on the next screen. The cost of each extra collar is $110.

Note that you can only use two collars at a time for the remote correction part of the Innotek IUC-5100. You can use as many collars as you want for the containment fence.

Katy November 24, 2010 at 6:04 pm

Hi, My daughter lives in the state of Michigan (lower northern) and has a large dog (bluetick/mix, more of a hunting dog) that doesn’t like to stay in the yard when she lets him loose. She has been wanting an under ground fence for him so he can have more freedom. I have read up on Innotek, and it has alot of very pleased customers. Can you suggest which company offers the best diy underground fencing? Also, since she lives in a state that is known for cold weather and alot of snow, does innotek still work in these weather climates? Sincerely, Katy

ADMIN – Hi Katy,

The systems work fine in cold climates. Where you get snow accumulation, you just need to turn up the boundary width dial to compensate for all that extra snow that the fence needs to get through. Then in the spring, you need to turn down the boundary width dial once the snow melts. Using an Innotek IUC-5100, in a suburban lot (anything under 5 acres), you can do easily get through a foot of snow.

ron November 18, 2010 at 12:17 pm

How can i test to see if a system will work next to the neighbors professionally installed system? I have a driveway that runs parallel to this boundary with minimal distance between property line. 2nd is there a standard distance that these installations should be to avoid this issue.

ADMIN – Hi Ron,

The only systems that work well beside each other are the one’s where at least one system can change operating frequency. Otherwise, you’d need to keep a minimum distance of 15 separation between shared boundaries. The Perimeter Technologies Ultra and the SportDog SDF-100A the two fence option that allows you to change the frequency.

Fred McMaken November 15, 2010 at 8:21 pm

I just purchased a new home and in the garage I found a radio fence box called “Radio Fence pet containment system”. It was made by Radio Systems Corp. Knoxville, Tenn. I do not have a co;;ar or do not know if it even works. Any info you can provide would be greatly appreiciated.

ADMIN – Hi Fred,

Radio Systems is the owner of PetSafe, Innotek, Invisible Fence, and SportDog, so unfortunately that does not narrow it down a whole lot! Take a picture of the system and send it to us and we can help you figure out what model it is. Alternatively if you can find a model number, that would be helpful.

As far as figuring out if it works, generally the control units last a long time – so you should be fine. To test it, switch it on, and see whether it powers-up and whether the status lights indicate a healthy boundary loop – or if the loop has a break in it. If it shows a break in the loop, then connect a small dummy loop and see if that makes the error light go away.

Melissa November 10, 2010 at 4:48 am

Good Evening,

I am moving to our new property and have 2 labradors of similar size. We are on 3.5 acres with the house situated in the middle of the block. I have a few questions

1. I also have a beach house without fences and need to contain the dogs
2. Is there a remote system I can use and transfer between the 2 properties?? so I dont need to purchase 2 wired systems.??
3. Are the adaptors compatible to Australian use??

ADMIN – Hi Melissa,

The only system that we have that will work with Aussie voltage is the Dogtra EF-3000 Gold (EU Edition). It is nearly identical to the EF-3000 Gold that you can see on our site. Shipping to Australia is around $150 and is not refundable.

You can take all the systems between houses. For the wired systems you need to have wiring in each location, but you can just unplug the base station and take it with you when you travel. I would be careful to write down the setting for each property so that you can restore them when you go back and forth – that way the dogs will have a nice consistent boundary.

Rich Preville November 6, 2010 at 7:09 am

I have a relative with an older IUC-5100 system, bought around 2004-05. Everything except the collar is in good condition. Would the new ones work with the older system? Thanks!–Rich

ADMIN – Hi Rich,

Yes, today’s 5100 collar will work your transmitter.

Lisa November 5, 2010 at 6:36 pm

I currently have the 4100 and I wish I went with the 5100. I would really like to have the remote. My GSD has been doing great with it for 3 months but am wondering if I can get it upgraded to the 5100. Do I just need to buy a new collar and remote? Or do I need to upgrade the Transmitter? Thank you!

ADMIN – Hi Lisa,

Glad to hear your German Shepherd is doing well on the system. The 5100 system uses different collars and has a remote, but it does use the same transmitter. So you would need to replace the collars and get a remote to upgrade you 4100 to a 5100, but you can keep the control unit.

Laura November 1, 2010 at 9:31 am

HI! I have an 8 month old husky and live on the side of a mountain. I would like to leave him out all day on a wired system so i was wondering if i really needed a stubborn dog system? He is kind of a baby when it comes to pain, but is true to his breed in stubbornness. I also get a lot of lightening here and only see one model with the lightening protection unit. Is that something i can buy separately or do i need to stick with that system? Also do they make long probes on the collars of all the systems.?

ADMIN – Hi Laura,

For Husky’s we always recommend the PetSafe/Innotek IUC 4100 for the reason you mentioned, Huskies are independent but are wimps when it comes to pain so don’t need a particularly strong system. You can simply add in a lightning protection module to your 4100 from the Accessories page. The system comes with long and short probes that you can interchange. The long probes are fine for a Husky, although you may want to thin out the hair around the probe region a little with some scissors to make fitting the collar easy. Since you’re considering the 4100 and lightning protector (which cost $319.95),take a look at the Innotek 5100 which is 319.95. The collar is a bit bigger, but it will not be a problem for your Husky. For the same cost you would also get with the 5100 the remote trainer and a roll of twisted wire.

Mike October 28, 2010 at 1:41 am

Hi, I would like to install the 5100 in my yard. My yard has a neighbors fence on one side. I do not wish to attached the wire to the fence because I don’t trust my kids not to damage the wire. If I run the wire underground at the base of the fence can I put it inside a pipe so my dog can run right up to the fence without receiving a correction. I was thinking of using metal electrical conduit. I appreciate your advice.

ADMIN – Hi Mike,

If you have a neighboring system you are likely to get interference. You may want to get a system with adjustable frequencies instead so that you can avoid interference from the neighbor’s system. Two good choices would be the SportDog SDF-100A or the Perimeter Ultra.

You can run the wire through conduit, but I would avoid using long stretches of metal conduit. PVC pipe works well. I also really like using old hose pipe or the flexible black pipe used for sprinkler systems.

You can set the fence up with any boundary width you want. But, it is hard to train the dog unless you have at least a few feet of correction before your dog reaches the fence. If the wire is going to be at the base of the fence, there would be no practical way to let the dog get right up to the fence. The only way to let the dog get right up tot he physical fence is to either have no boundary wire in that section or to put the wire on your neighbor’s side of the fence.

Robert Coleman October 22, 2010 at 9:20 am

Is the collar for the 5100 model waterproof? How much wire comes with the system?

ADMIN – Hi Robert,

Yes, the 5100 collar is completely waterproof. It’s even safe if your dog jumps into the pool.

Austin October 20, 2010 at 11:12 pm

I have a 7 month old American bulldog. I have about an acre fence in backyard, and he is digging through under the chain length and destroying my vinyl privacy fences. I want to wrap the yard with underground fencing. I also would like to keep him off the backporch to keep him from getting to our shoes. Which would be my best fence to go with? I’m thinking the 5100. What type of boundry should I start with, and how long will it take for him to know his boundaries?

ADMIN – Hi Austin,

The easiest layout would be to wrap the whole yard in a big loop and then train the dog. A couple of weeks later when the dog is trained, either add a secondary loop to protect the porch and shoes – or add a pawz-away outdoor zone (the fake rock looking thing – http://dogfencediy.com/store/accessories/pawz-away.html) to protect the shoes. I find it easier to train dogs on a simple layout – then add in extra little bits later once the dogs have it down.

The IUC-5100/4100 would be a good choice, if you wanted to use the outdoor zone. Another one worth considering would be the PetSafe Stubborn – sometimes the bulldogs need a little stronger system to feel the correction.

Kristin October 17, 2010 at 9:00 pm

Hi! I have a 9 month old GSD puppy, and 11 acres, partially fenced in “hot” wire for my horses. I am considering purchasing the IUC 5100, but am concerned over instalation. I read on another website that the wire MUST be in contact with the ground, but above you state it can be zip tied to an existing fence – in my pasture areas, I would like to be able to run the fence wire on the posts already installed for my horse fencing, for several various reasons (I pratice rotational grazing, so the dog’s boundarys would be easy to move to coincide with the horses for one…). Can I do this? Thanks

ADMIN – Hi Kristin,

We recommend that you keep a minimum distance of 6 feet from the electric fence. For 11 acres I’d advise 10 to 15 feet separation considering you’ll be setting a wide boundary width. If your fence was not electric, it would have been okay to attach the boundary wire to it. Large surface area metal is the type of metal to avoid as well as utility wires in general.

Mélanie October 16, 2010 at 6:28 am

I am really interested in purchasing this fence but I have underground electricity, phone line and cable. Will it be ok if I install the wire in a parallel direction as my electric line but at least 10 feet from it? thank you

ADMIN – Hi Mélanie,

Ten feet of separation is fine. I would only start being concerned with six feet or less of separation.

Often you can even get away with having the wires all right on top of each other. The reason we separate wires is that sometime when you have parallel wires close together, the dog fence signal jumps into the other wires. So you get the dog fence signal going everywhere the phone wire goes. That rarely happens, but if you are going to run wires close together (less that six feet), you just need to test it – after you have layed out the wire, use the collar to test around the house to see if the collar is triggering where the wiring runs or where the power/phone outlets are located. If you do get this happening, you just need to play with the dog fence layout a bit to either get more separation or angle the wire more so that it is less parallel.

But for you, since there is ten feet of separation you don’t even need to do this step.

Michelle October 14, 2010 at 6:54 pm

I am interested in purchasing the fence for our 40 pound beagle. I’m just a little confused about the installation. Is the wire buried in the ground?

ADMIN – Hi Michelle,

The wire can be buried at 3 inches in the ground, stapled to the lawn with lawn staples, or even attached with zip ties to existing fencing. We have customers do all 3 with one boundary. Some staple the wire in wooded areas and bury the wire close to the home.

Tony October 4, 2010 at 11:08 am

I have an IUC 5100 system for my two dogs. Introducing the dogs to the fence, the Ridgeback showed strong recognition to the boundary. The very hairy, Australian Sheppard/Border Collie mix walked back and forth over the wire trying to understand the beeping sound. Is the only way to get the system to work for the second dog involve shaving part of her neck?

ADMIN – Hi Tony,

I would make sure you have the long hair probes on the 5100 collar for the Aussie/Collie. I would also trim a little of the fur with scissors. You don’t want to shave the neck, just thin out the fur a little where the probes contact the skin. Then put the collar into the fit test mode and get the collar on right. The first couple of times are tricky, put one you get used to it and know what it should feel like it is easy.

Paul Whaley October 4, 2010 at 12:31 am

Hello, I am attempting to select the appropriate system for my chocolate lab who continually roams my road. He is about 80lbs and growing at 1.5 y/o and I live in a wooded area with 1.5 acres of yarded property. I dont have many requirements for a system other than it needs to work well since he is extremely active. I have been thinking about a wireless system but am really unsure the pro/con of wireless vs traditional buried wire. I am unsure about using rechargeable batteries however I would like whatever system meets the above scenario and is going to work effectively for our needs. Can you please provide some information? Regards Paul

ADMIN – Hi Paul,

With a Labrador Retriever you have a lot of options, they are generally both easy to train and receptive to the correction. I would definitely use a wired fence, they work a lot better. If you want something rechargeable, the Innotek IUC-4100 is a good choice. If you want something with a remote trainer, the IUC-5100 is a good choice. The SportDog SDF-100 is a good choice if you want a system with a disposable battery (it uses a regular 9V battery). The SportDog has a little bigger collar. Both are good reliable systems. Combine either with steady training for the initial two weeks and you should have a happily contained (although still hyper) chocolate lab.

tony September 27, 2010 at 3:14 am

We have 2 Huskies, 1.5 year olds. they are fixed but still dig under the fences to get out all the time. they are brothers and almost same size. because we can’t exercise them everyday, they get crazy and dig. they yard is all dirt, so digging a wire is ok, I just do not want to deal with it. I saw a company that has a WIFI transmitter that seems cool too. What do you think of those?

ADMIN – Hi Tony,

If you’re considering wireless, my recommendation is the Havahart. It is by far the best wireless system on the market. The Perimeter Technologies WiFi system doesn’t work all that well and if you’re considering the PetSafe Wireless, you mine as well go with the Havahart cause you can create a much larger boundary, the boundary line has the least amount of fluctuation, and the collar responds the quickest among the other wireless brands.

Bob Kirchner September 3, 2010 at 4:18 pm

Very helpful information. My neighbor and I are considering putting in a IUC-5100 system covering both of our yards. Our dogs love to play together. I have been unable to find any information on the ability to order a second remote trainer – cost and how to order. Any information you can provide would be geratly appreciated.

ADMIN – Hi Bob,

Unfortunately, the remote trainer for the 5100 can only be purchased with the fence. We can sell the extra collars, but the remotes are not sold separately.

Debbie August 31, 2010 at 4:57 pm

I noticed that you said that the control box should be kept above freezing. I live in north western wisconsin. My garage is attached to the house but it defiietly is below freezing in my garage many days during the winter. This is where I plan on keeping the control box. Is this going to be a problem?

ADMIN – Hi Debbie,

Beyond the review, I’ve contacted Innotek directly. Freezing temperatures will not be an issue. The key is to install the wall transmitter in a place that is safe from wind and rain. This makes the garage a great place to install it. We sell these units to customers in every climate in the U.S. and Canada. I haven’t heard of any transmitter issues from our customers resulting from extreme temperatures, so you should okay to install in your garage.

Jill Zimmerman August 25, 2010 at 11:02 am

Hello- I did a bit of skimming on both the Innotek 4100 and Innotek 5100 and didn’t find anything that really jumped out at me so: What is the difference between the two?

ADMIN – Hi Jill,

The 5100 adds remote correction. This means that the 5100 has a little remote control that can be used to correct the dog by pressing a button. Remote correction training is popular with people training hunting dogs, we find it less useful for training non-hunting pets.

The base stations of the 4100 and the 5100 are exactly the same. The collars look similar for the 5100 is about 50% bigger than the 4100. The collars are intercompatible for use as a dog fence, but only the 5100 collars can be used for the remote correction.

The 5100 also includes the lighting protection and 100 feet of twisted wire in the box, these are optional extras on the 4100.

Can anyone tell me if I was to put the radio wire thru an electrical conduit if the frequency will be cancelled? I already have a natural fence on one side o fthe property and my dog goes along the fence line to go the bathroom in the trees. I do not want to disscurage this but need to complete my loop for the system. I was thinking that if I put the radio wire in electrical conduit, that would cancel out the signal????? Any help would be appreciated! Thanks Chris

ADMIN – Hi Chris,

Unfortunately the signal cannot be blocked consistently by electrical conduit. You could try running the wire along the top of the fence to complete the loop. If the wire is high above the ground, the signal will not reach your dog on ground level.

Laura August 4, 2010 at 3:12 pm

I am considering a 5100 system but only one of the dogs would need trained with the remote. Would a 4100 collar work for the second dog which I do not plan to remote train? Thanks.

ADMIN – Hi Laura,

Yes, you can use a 4100 collar with the second dog that you don’t plan to remote train. The IUC-4100 collar is compatible with the IUC-5100 system. The 4100 collar will be a bit lighter and a bit cheaper so is a better choice for dog’s that you don’t need the remote training.

Susan July 18, 2010 at 5:10 pm

Hi I am thinking about getting the Innotek 4100 but I like the idea of being about to page the dogs when I want them to come in which the 5100 would be able to do but we have 4 hunting dogs that are use to the dogtra training collars… We have an 2 English setters, a springer spaniel and a mixed lab springer, setter. Would this be a good choice to keep them all in a 2 1/2 acre yard? And be able to get them to come in when I want them to?

Thank you for any advice

ADMIN – Hi Susan,

The 4100/5100 would be a good choice for containment for those dogs.

The 5100 is competent but not great in remote mode and has a number of limitation that may make it less useful for your application. First, the useful range of the remote is only about 100 yard, it is nowhere near as powerful as a dedicated Dogtra training collar, which may not be far enough in your property. Second, the remote only has two channels – so you could not control each of the four collars independently. Third, for the remote to work, the collars have to be in training mode and that severely reduces their battery life from about a month between charges to about three days.

I have had problems with one of my large dogs (suspected lab/mastiff mix) jumping the 3ft chain link fence of my backyard. I will be moving in a couple weeks to another house which also has a 3ft chain link fence. I am wondering if it is a good idea to begin to introduce the fence at the time when he is first learning terrain? Also, if I intend to run the wire on the fence, do I still need the flags to mark the boundary? Or will he recognize the fence as a boundary even though he has jumped the fence many times before at the old house? Do you think the 5100 is a good choice?

I am also wondering if it is possible to setup a “forbidden” area inside the house, using the same collar to provide correction and some kind of add-on? I would like to train both him and my other dog, a lab, to stay out of a particular bathroom so that my poor cat will have an area of peaceful enjoyment. I’m not sure I could use the remote for this, because he clearly knows or senses when I am within hearing range, and only ransacks the kitty litter box when I am not aware he is doing so. If there is such a thing, would it be better to introduce it at the same time as the outdoor fence?

ADMIN – Hi Kate

Hi Kate,

(1) I would install the fence when you first move in. It is always easier to be consistent with the new boundaries than to introduce new rules later on. But, no big deal either way.

(2) Where you have an actual physical fence there is less need to use the training flags. I still like to use them. They are an extra reminder and let the dog know how close to the fence they can get. It is also very useful to have the dog trained on flags in case you move or go to a vacation house … once a dog recognizes the flags it is very easy to teach them other locations. But, again no big deal either way.

(3) Either the Innotek 4100 or 5100 would be a good choice for a lab/mastiff mix.

(4) To keep them out of an area of your house, use one of the indoor pods, they create a small area that excludes the dog. Using the remote is a bad idea for training the dog to stay out of certain areas. Because you are not always around it is hard to be consistent. At best, people usually just end up training the dog to be a sneaker (teaching them not to do something when they are around but that they can do it when you are not looking).

Nikos June 9, 2010 at 10:35 pm

We are going to be moving to an 8 acre property that will have both our house on it and a working nursery. Is it possible to make 2 separate zones of coverage — one being our 3 acre backyard, and the other being the entire 8 acres. We have two dogs — an Australian Cattle Dog (5) and a Vizsla/Giant Dachshund Mix (2). The reason behind this is to have the flexibility to allow the dogs access outside in the backyard (and out of the nursery) when vehicles and equipment are in use in the nursery. When there is no activity I would like to open up the rest of the property to allow them to have access to the entire 8 acres.

Is this possible to do or do you have any other suggestions?

ADMIN – Hi Nikos,

You can run two separate boundaries and alternate which loop is plugged into the transmitter. The other way would be to run two transmitters.

Chuck May 2, 2010 at 12:17 pm

We just became became owners of a 3 yr old Australian shepherd mix. So far a great dog except that she loves to chase…….. anything including cars. We live in a rural area with all kinds of wildlife so we are looking for a yard containment system that will handle a dog that’s on the move. She weighs 55#. Also is the 5100 compatible with deep snow? Thank you

ADMIN – Hi Chuck,

With a fast moving dog that likes to chase like an Aussie, if possible you want to set up the system with a nice wide boundary, particularly during the training phase. That way the dog cannot easily run through. When trained right the dog should rarely if ever run through the fence line so will not realize that running through is a possibility. Particularly with dogs like this, you want to spend a few days at the end of training testing the dog with it’s trigger points to make sure they learn that they must obey the boundaries when they get excited. (so get a confederate to drive by in a car, or to walk their dog past). The best way to help a dog overcome a particular trigger point is to work with them with that trigger point. Your are lucky because Aussies are smart and quick learners so it should be a quick process.

There are a few good choices with an Australian. The Innotek IUC 5100 or PetSafe Ultrasmart would both be a good choice and are rechargeable. The PetSafe Stubborn, or a SportDog SDF-100 are also good choices that are a little bigger, but also a little cheaper.

You can increase the boundary width on the control box when the snow starts accumulating to compensate for the depth of snow cover. Where snow is likely to be an issue, get a unit that have a capacity well above what your need. For example, the 5100 and Ultrasmart can do 25 acres, but if you know you need to crank up the boundary width when it snows don’t use it when you are doing more than say 12.5 acres. Similarly, the SportDog is rated for 100 acres, but if snow is an issue, don’t use it for more than 50 acres. You can also use a thicker gauge of wire to help increase the boundary width to help you get through snow.

steve May 1, 2010 at 12:17 pm

I plan on using 1000′ of 12 gauge solid wire. I only want my dog to access the back yard. So I plan on running the wire close to the front of the house for my complete loop. However it would be running parallel and adjacent to low voltage lighting wire which I believe is DC. With this interfere with my system?

Also I want to mount my transmitter in the garage but I wont be able to see it all the time to check for errors. Which system has error lights built into the collar?

ADMIN – Hi Steve,

Low voltage lighting rarely causes system interference, but sometimes with parallel runs of wire and low voltage lighting, the electronic dog fence signal gets into the lighting cable, making everywhere that cable runs effectively part of the dog fence boundary. If you do run those parallel sections, you want to make sure to test to see if this is happening, and if so moving the boundary wire.

Unfortunately, none of the systems tell you if there is a boundary breakage at the collar. But most of them (like the Innotek 5100) have an alarm that sounds at the base station to alert you to the break.

Gordie April 27, 2010 at 2:43 am

Trying to decide between a 4100 or 5100 for my 7 month old Golden? I wanted to use the remote in the large fields attached to my property, mostly for getting his attention and to respond to my come command. He gets at least 2 walks per day. Don’t need the Zones for the house.

ADMIN – Hi Gordie,

Both the 4100 and 5100 would be a good choice for a lab. The difference in collar size is not going to be a big deal, and the price difference is small (especially if you needed the twisted wire or lightning protection anyway). I would go with the 5100. Just be sure to wait a few weeks until the fence training is complete to start on the remote training; and try and work with a friend or trainer that has experience doing remote training for your first couple of sessions. You have to use the remote trainer in a very structured way for it to be effective.

bob barry April 10, 2010 at 12:10 pm


Admin – Hi Barry,

The Innotek 5100 does not need any booster for use with 1,500 feet of wire. You can do up to 25 acres (5,000 feet) of wire without any issues. The collar takes between one and two hours to charge. A charge is good for about one month on just containment mode, and is good for about three days in training mode.

Steve D April 6, 2010 at 1:24 pm

I have a 14 week old golden doodle puppy that I am shopping for. I wasn’t sure at what age would be safe to start with the invisible fence. I was hoping to install the system myself and do the training too. Also two of my friends have a fence system called DogWatch and mentioned getting that so my pup can enjoy off-leash play time at both locations. I have hundreds of flags to re-mark the other yards for training at multiple locations. I didn’t see any reviews on the dogwatch system and was wondering if anyone was current user of it. Im going to need 420′ of the boundary wire and 90′ of the twisted wire of what would be the best system for my dog. I was thinking of just getting a remote collar and line the yard with flags and do the training as if i had installed a fence there… the issue with that is I don’t want to rely on my older parents to have to look for a remote when i travel and give corrections at the wrong time. but that seems like the easiest install. a trip up to my brothers with a remote and a couple dozen flags makes me feel like i can have a fence anywhere. Im lost on what to do and im sorry for being all over the place with my comments and ideas. any help would be great

ADMIN – Hi Steve,

I would like to see you wait till the pup is six months old. Before that, most dogs aren’t mature enough and don’t have the attention span for the training to be effective. If you have already worked with teh dog and they can confidently do a sit/stay/come, then you can start a little earlier. The IUC-4100 and the IUC-5100 would be good choices for a golden doodle.

DogWatch is full service company that does installations. If you want a system compatible with your friends, it would be worthwhile giving them a call to get some information from them. They make good products, we hear good things from their customers.

I would avoid trying to teach the dog with just a remote training collar. It rarely works. Because nobody is patient enough to watch the dog all day, you end up being very inconsistent and at best you just end up teaching the dog not to escape while you are watching. But, once the dog is trained on a proper fence system, you can sometimes (but not always), do a temporary fence with just flags and the training collar. (e.g. we have some people that set up a temporary fence when they take the dog camping or on vacation)

Jim March 29, 2010 at 10:33 am

I’m trying to decide between the 4100 and the 5100. I have a Lab/Retriever mix and likely will not be training him with the remote but I was wondering if it would be useful for times when we bring him places where he isn’t fenced. Will it just confuse him or can it be used effectively at a friends house for example? Typically I just bring a stake and a leash when we visit and that works fine but I was wondering if the remote would work to give him a little more freedom.

ADMIN – Hi Jim,

Once the dog is trained, you can often get quite impressive containment results just by plonking the flags down when you take him to a friends house. You can even do a quick training session on the new property boundary. Often, but not always that will be plenty to keep the dog contained. You could definitely reinforce the flags with the remote, but you would have to keep a watchful eye on him, the remote is of course no good if you aren’t watching the dog. Again, that will not work for every dog, a fraction of dogs are just going to learn to wait till you are not looking to make a bolt for it.

I would avoid using just the remote without the flags. Our training philosophy is that the dog should no exactly what they are supposed to be doing before you correct them. If there is no clear demarcation for the dog of where they should not go, correcting the dog tends to lead to general fearfulness.

Emily March 21, 2010 at 11:23 pm

Can you plug the 5100 transmitter in inside your house?

ADMIN – Hi Emily,

Yes, all the systems plug into a regular 110v wall outlet. Most people will put the transmitter either hidden away in the house (I like to use a closet) or in their garage.

bob barry March 20, 2010 at 5:44 pm

I am an above-knee amputee with a shepard/retriever mix that I am training with a sportdog field trainer400. Is there any underground fence, or other system, that would work with this collar and transmitter? Is it true that 16G wire would last longer than 18 or 20G that comes with most systems? I would need to install about 800 to 1000 ft. Also, would it be better to staple or bury wire? I have to go under a gravel driveway and deal with some wooded area.

ADMIN – Hi Bob,

Afraid that none of the systems will work with any of the dedicated training collars, like the SportDog Trainer400.

Our experience with wire has been that it does not make a big difference. The most common cause of the wire failing being cut by a mower or edger. It does not particularly matter what gauge you use, if a mower hits any wire it is going to sever it. As for wire degrading in the ground, the jacket is more important than the gauge, you always want something that is rated for direct burial. I encourage people to save their money and get the thinner 20 gauge for the vast majority of installations.

Shelly Floyd February 5, 2010 at 6:56 pm

I’m trying to figure out if this will work on the back part of our property. We’re in Florida, and the back half is swamp 3-4 months of the year. During the rainy season, it can fill up to a foot deep with water. If we install our wires when it’s dry, will they continue to keep our Border Collie/Black Lab mix in the yard when it fills with water? Or will it somehow short out the signal? This dog loves water, so I know that she’ll be out there in it. Thanks in advance for any advice!

ADMIN – The wire does not mind getting wet. Try to keep any splices out of the waterlogged area (but not the end of the world if you can’t). The signal still transmits through water, but you may want to increase the boundary width a little when you get those rains to compensate for the water depth.

John Alberts February 3, 2010 at 5:36 pm

I just purchased an Innotek 5100 from you guys and spoke to Bob Holmes in the process. He recommended a hunting dog training book for help in using the remote with the collar. I looked on Amazon but wasn’t sure which book he meant. Does anyone there know the title or author?

ADMIN – Hi John,

The book I liked for showing you how to use the remote correction with your dog was “Training the Hunting Retriever ” by Robinson. I am sure there are lots of other good one I have not read. If anyone else has suggestions, I would love to hear them.

phillip January 7, 2010 at 3:58 pm

i have a st. bernard and was woundering if this will work because he is about 200lb

ADMIN – Hi Phillip,

Considering going with something with a little more powerful correction, like a PetSafe Stubborn. An IUC-5100 will probably be fine — st bernards are usually motivated by the correction, but do need a higher correction than say a lab due to their size. It is hard to tell how any individual dog will react, if you think he is going to be sensitive to the correction go with the IUC-5100 and we would be happy to swap it out for a stubborn is it proved insufficient. If he is a little tougher, start out with the stubborn.

Angela January 3, 2010 at 12:22 pm

If I already have the fence can I purchase the remote trainer seperately?

ADMIN – Hi Angela – you can purchase remote training systems separately. Or you can get an IUC-5100 collar separately and the remote control separately. But you cannot use a PetSafe Ultrasmart collar with the remote control — you need the larger 5100 collar, only this has the receiver built in.

Julie December 20, 2009 at 11:56 pm

I already have the standard ultrasmart fence. The collar went bad and I was wondering if I bought the collar and remote extra for the 5100 system would it work with my PetSafe Ultrasmart existing system?

ADMIN – Hi Julie,

A collar and remote from the 5100 would work on an PetSafe Ultrasmart system.

K Hayward November 10, 2009 at 7:20 pm

I have an older Husky (13). She has started both digging under the fence and destroying door jams over the last year. I am both worried about her safety if she gets out but also about the property we are renting. Primarily I want something that will keep her in the backyard but allow her in the house. Secondarily, I would like to keep her away from the doors unless she is coming inside. What is the most effective way to do this? I was thinking the remote training collar and the invisible fence. Suggestions?


A dog fence would work well to keep her in the yard. You could use the indoor pods to keep her away from the doors, or alternatively a “scat mat”. The remote training doesn’t have great results for this kind of thing because you have to be around to observe and correct the behaviour which is usually not the case, especially with huskies who tend to escape only when left alone. Even if you are around, the dog just learns not to dig at the door while you are not around. You really want something more automatic to keep them away from doors like the indoor zones pods (you can get them on the Innotek IUC-5100 and on the PetSafe inground systems), or a scat mat.

Nicole October 21, 2009 at 11:02 pm

How do you change between dogs with the one remote control? Is it something where you can do it as your out and about or is it a toggle switch type under the back cover?

ADMIN – Hi Nicole,

The remote control has a button on the front that switches the mode from one dog to another. You press it once and you get dog A, press it again and you get dog B, press it a third time and you get both dogs.

Michael October 10, 2009 at 8:50 am

I’m thinking about getting this for our Lab and Golden Retriever. It’s nice that it allows two collars and the dogs are the same size so it sounds like it will work well. I like having the remote control for training but how does that work with two dogs/collars? If I correct one, does the other get a shock/tone as well? Can I select which collar is connected to the remote?

ADMIN – Hi Michael,

The remote control lets you select each dog separately or both together. So you could correct one dog, but not the other. (note that you can only do this with two collars at a time, it does not work with 3+ collars)

Nichole October 3, 2009 at 7:54 pm

We have a 30 pound Beagle and a 60 pound lab that we would like to get a fence for. I see that the PetSafe Ultrasmart isn’t set up to have different settings for dogs of such different sizes, but none of the other Pet Safe models seem to meet our needs either (rechargable batteries, waterproof collars, etc.) Can the Innotek 5100 model accomodate dogs of different sizes?

ADMIN – Hi Nichole,

The IUC-5100 is not a good match for dogs of different sizes, since you cannot independently adjust the correction level for each dog. If you want something rechargeable, the best choice would be the Dogtra EF-3000 gold. It is rechargeable and lets you set the correction level for each collar separately.

Al July 20, 2009 at 10:00 pm

I saw the quote below on another review…have you heard of this issue before with neighboring underground fences? If so, does it apply to the Petsafe Ultrasmart as well?

“Because of the zone feature in the 5100 model, the collar will not work if your neighbors have installed a inground training fence. Our neighbors have a non Innotek professionally installed system. We installed the Innotek 5100 and the collar disables itself within 15 feet of the lot line – system works fine on the other three sides. Innotek’s solution for this is to move our fence more than 15 feet from the shared lot line, considering our fence is currently only 12 feet from the house on that side of our yard, this is impossible. I do not understand why Innotek would make no mention of this in the instructions or even in small print on the box, so customer could avoid the effort of installation for no reason and frustration of trying to troubleshoot the issue.”

ADMIN – Hi Al,

None of the systems like being near another fence. You can usually get within six feet unless you neighbor has their fence set to a really wide boundary. Then you need to ask them to narrow their boundary width a little. The best systems for this problem are the Perimeter Technologies Ultra systems, that you can switch to multiple frequencies to try and avoid interference.
