PetSafe Ultrasmart Overview

Summary: Excellent Value for Money

The PetSafe Ultrasmart PIG00-13619 (formerly Innotek IUC-4100) has enjoyed nearly a decade as our top-dog fence. But, it is starting to show it’s age and has been surpassed by the new PetSafe YardMax which does more at a lower price. It is still an excellent and reliable system at a good price.

Sound Fundamentals

We still love the fundamentals on this system. Build quality is great, the collars are slimline, and the batteries rechargeable. The system also includes nice-to-have features such as battery backup, indoor/outdoor zone compatibility, collar-fit testing mode, and progressive correction.

No Independent Correction

Out of the box, the system doesn’t support independent correction levels for different dogs on the same system.

Lightning Protection

PetSafe have started including the lightning protection module free with the basic system. This is one of the few systems where this is not a $40 an optional extra.

Slim Rechargeable Collar

The killer feature of the PetSafe Ultrasmart is the collar. The system is built around a slimline rechargeable collar. It performs the magic act of being one of the smallest collars, but still being powerful and full of features.

Slimline and Lightweight Collar

The PetSafe Ultrasmart collar is the thinnest full-sized containment collar. While the collar is small, PetSafe stretched the collar to achieve the slimline finish. This makes the collar less visually obtrusive on your dog. While many collars can appear like a big box hanging under your dog’s neck, the PetSafe PIG00-13619 has a much smaller visual footprint.

The collar is also lighter, allowing it to be used with dogs as small as 12 lbs. For dogs smaller than 12 lbs, a dedicated small-dog system such as the PetSafe Little Dog Fence is more appropriate.

Rechargeable Lithium Ion Battery

The Ultrasmart collar is fully rechargeable. To charge, simply place the collar in the included charging cradle. The collar light remains red while charging, then change to green when it is fully charged. A full charge takes 2 hours and lasts about 4 weeks.

The battery and collar have shown excellent longevity and are proven to last. Owners of the previous iteration of this collar, (the Innotek IUC-4100) report collars and batteries continuing to perform after 6 or more years of use. That said, the collar battery is not user replaceable so if the battery does fail you will need to send the whole collar back to PetSafe for replacement (around $35).

Long and Short Contact Prongs

The standard system includes both long and short contacts (prongs) in the box. The collar prongs can be unscrewed with the included tool and replaced with the long prongs for long hair dogs, or the regular prongs for short hair dogs.

No External Controls

There are no controls on the collar itself. Instead, the controls are located on the transmitter box. Having the collar free of buttons and knobs makes it smaller and more durable because controls on a collar are more likely to break or malfunction.

The system includes a pair of yellow no-correction caps that can be placed over the prongs to prevent a correction being felt by the dog. This is useful in the first week of training where you want to be able to teach the dog the boundary without issuing a correction.

Plastic Collar Band

The collar has an integrated integrated design. It is made of high quality plastic, and some of our team considers it modern and sleek, but most of us would prefer a cloth band. The collar is waterproof and wears really well. Our oldest collars appear new with the exceptions of a few scrapes. The collar closes using both a traditional buckle and quick release buckle for adjustments and fitting.

Three Progressive Correction Levels

The correction level for the collar is set at the transmitter. The collars have three progressive correction levels: Low, Medium and High. The correction starts at the level you set, but then increases the longer the dog lingers in the correction zone and the closer the dog gets to the boundary wire.

The correction range on this collar is suitable of almost all dogs, but may not be quite strong enough for the most hard-headed breeds. Dogs that are particularly insensitive to the correction such as fighting and guardian dog breeds may need something stronger. (e.g., Pitbulls, Dobermans) These dogs would likely benefit from a stronger system such as the PetSafe Stubborn.

No Independent Correction Levels

While the lack of controls on the collar is a positive feature for durability, it also means that you cannot set the correction level for each dog independently. (There is a workaround, the resistor hack.) Every dog must to be on the same starting correction level. Thus if you have two dogs that are very different in size (> 30%) or temperament, then the PetSafe Ultrasmart is not the best choice. Instead consider a system with independent correction such as the Dogtek EF-6000 or the SportDog SDF-100A.

Quiet Beep

The warning beep on the collar is not loud enough for the human trainer to hear. To make the collar durable and waterproof, PetSafe sealed the speaker inside the collar. While this is great for waterproofing, this leads to a muffled warning beep that is hard to hear for adults (children and dogs seem to be able to hear just fine!). This means that during the training phase you need to either have keen ears, or rely on the collar indicator light and/or the dog’s body language to know if the collar has been triggered.

Collar Fit Test

The PetSafe Ultrasmart collar helps you get the collar fitted properly. Improperly fitted collars are the second most common reason (after lack of training) an in-ground dog fence doesn’t get 100% containment. Improperly fitted means the probes do not make contact wit the dog’s skin. When this happens the dog does not consistently get the correction and learns that the boundaries can be ignored. This issue is particularly relevant to long-hair dogs where fitting the collar can be tricky.

The Ultrasmart has a ReadyTest mode where the collar makes a clicking sound when it is properly fitted. This eliminates guessing and lets you get a perfectly fitted collar every time.

petsafe ultrasmart transmitter


The transmitter (aka. base station) connects to the 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.

Boundary Wire

Direct Burial Rated Wire

The wire is direct burial rated, meaning that it will hold up better in the ground than standard electrical wire. The boundary wire is surrounded by a PET jacket. This protects the wire against the elements better than standard PVC coated electrical wire that will tend to rot, particularly in acidic soils.

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 Ultrasmart basic kit includes 500 feet of standard 20 gauge wire, 2 wire splices, and 50 marking flags. This is sufficient to cover 1/3 of an acre. Extra wire, wire splices, and marking flags can be purchased in our store. The 20 gauge wire kits cost $30 and include an extra 500 feet of wire, 2 splices, and 50 marking flags.

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 system includes a blue tester tool that lets you check if the transmitter and collar are working. Hold the tester tool against the collar probes and when the collar is activated by crossing the boundary line, a light on the tester tool will glow.

petsafe ultrasmart wireless zones

Indoor / Outdoor Zones

The PetSafe Ultrasmart is compatible with wireless indoor and outdoor zones. These wireless battery powered pods can be used to create small circular exclusion zones from 2 to 12 feet in diameter to keep the dog out of small areas. For example, drop one of the indoor pods in a room to stop the dog going into the room, or slip it under a sofa cushion to keep the dog off your couch. Or use the outdoor pods to keep the dogs out of flower beds or a fish pond.

The Ultrasmart is the only system that has these indoor and outdoor pods available. The PetSafe Deluxe, PetSafe Little Dog, and PetSafe Stubborn Dog Fence systems have indoor zones available, but no outdoor zones. No other system has either indoor nor outdoor zones.

PetSafe Ultrasmart One Year Warranty


The system also has a limited one year warranty. After the one year there is a fixed charge for repairs. The repair charge depends on what part breaks (around $30 – $50). Build quality on these units is excellent so hopefully you will never need it.

↑ Top


The PetSafe Ultrasmart enjoyed a run of nearly ten years as our go-to system. It is still a good reliable fence that does all the basics well. In addition you have some useful features such as the slimline rechargeable collar, the collar-fit test, and the compatibility with indoor & outdoor pods.

The Ultrasmart does have a few deficiencies, most notably not being able to adjust the correction level for each dog independently. But, if you don’t need the extra features, the PetSafe is an excellent choice.

But, it’s biggest deficiency is that there is a newer system on the block the PetSafe YardMax.

We recently got 3 puppies, their mother was a pure bread Akita and their father was an unknown (probably mostly German shepherd, but that’s only a guess). They are currently 2-1/2 months old. We have over 11 acres, with a river cutting through it. We would like to install an electric fence so that we can let them run free (they are indoor dogs, but they need lots of exercise and we want to give them as much space as possible. What system do you recommend? Also, how do you recommend we handle the river? (Ideally I would like a way to electronically fence off only the portion of the property on the side of the river with the house, this is the majority of the property 9+ acres. However, I would like them to be able to play in the river with the kids and such when supervised.) I would appreciate any suggestions Thanks!

ADMIN – Hi Michael, according to your goals, I would recommend excluding the river and fence in your 9+ acres. I highly recommend you upgrade the wire to 14 gauge. The 20 and 18 gauge are too thin to hold up to that amount of acreage. The SportDog SDF100A is with the added thick fur probes is the system I would recommend for your Akita mixes. The manufacture is the only place to find the thick fur probes. For 9+ acres, you’ll need to add an additional 2,000 feet of wire to your order.

Jared November 25, 2012 at 6:22 pm

Hey Stewart. I have a back yard with a chain link fence. My dog has never attempted to jump over it, but the last few weeks he has started jumping more and more. He can now clear my sectional couch with ease. Would you recommend this model as just a precautionary measure or is there another model you would prefer? Thanks for the great website!

ADMIN – Hi Jared, this would be a great fence for your backyard containment solution. You can run the wire along the top of the fence. I would recommend you review the backyard loop layout options on our layouts page located under Installation on the menu bar at the top. Back yard loops require a bit of extra planning since the fence operates in a closed loop only.

Mike Pennington November 25, 2012 at 9:04 am

Hi there….as we have a pretty diverse range of dog sizes in our household, was just wondering if the PetSafe Little Dog collars would work with the larger PIG00-13619 system. Essentially, how do you get best-of-both-worlds benefits from a single dog fence solution? We like most everything we read regarding attributes of the better rated systems, but concerned that it may be too much for our Yorkie vs. our Chocolate Lab. Any suggestions? Thanks, -mp-

ADMIN – Hi Mike, the Little Dog collar will not work with the Ultrasmart PIG00-13619 unfortunately. For your mix of dogs, we recommend going with the PetSafe Deluxe and bundle in the little dog collar.

Debbie November 7, 2012 at 11:16 pm

We were looking at the Innotek ICU 5100 but decided we don’t need the trainer, so we figured we just needed the ICU 4100. Is the IUC4100 the same as Petsafe Ultrasmart PIG00-13619? We have 4 acres and a golden/lab mix puppy – we expect him to be about 40 lbs. Thanks!

ADMIN – Hi Debbie, yes they are the same fence. The only difference is that the PIG00-13619 includes the lightning surge protector. This will be a great fence for the size of lab mix you have. We recommend you upgrade your wire to 14 gauge for maximum strength wire and you’ll need to bundle in an extra 1,500 feet of wire to cover 4 acres of property.

D folk November 5, 2012 at 1:04 pm

We are on a farm and would like to enclose 5-10 acres. What is the cost for extra wire and flags over the cost of the system?

ADMIN – Hi D Folk, the cost depends on the gauge. For a 500 foot roll of wire, 20 gauge is $21.95, 18 gauge is $31.95, 16 gauge is $69.95, and 14 gauge is $79.95. We recommend upgrading to 14 gauge on installs greater than 500 feet. 14 gauge will withstand the wire breaks from tree roots that simply snap the smaller gauges. For 5 acres, you’ll need a total of 2,000 feet of wire and for 10 acres you’ll need a total of 3,000 feet of wire.

Frank Parkinson November 2, 2012 at 7:52 am

I’ve installed the Innotek 4100 system (CORRECTION – It is the Innotek SD2100E, not the 4100) and it has worked well for 10 months to contain our English Setter in just over five acres of woodland and olive grove. The wire runs mainly in the bed of streams – these have only got water part of the year. Previous breaks in the fence (caused by wild boar) resulted in the system alarm sounding and were easily repaired. This week, however, after torrential rain and flooded streams, the wire has been broken in several places and the broken ends are separated by several meters. The alarm does not sound, and the green light is steady on the control unit. I thought that it may be a problem with the broken ends being under water and therefore providing some continuity – so I pulled one end out of the water. Still no alarm! If I remove one end of the wire from the control box the alarm sounds (as it should). Have you any suggestions as to why the alarm is not sounding? After some thought I can only imagine that there is also a break of the insulation in a part of the dog fence where the wire is twisted. Thus, if the wire shorts a continuous loop will be made and the alarm will not be activated. The water is flowing too strongly to check this at present, but I am certain that it will be the answer. I am pretty confident that there is not a fault with the control unit. Thanks, Frank

ADMIN – Hi Frank, I believe what you say will be the answer. The ground can “complete” the loop as we have seen in our testing. So, sometimes, there can be a break but no alarm.

Randy October 17, 2012 at 1:31 pm

hello my name is randy and we live in town I have a long but narrow yard and I’m looking for a fence recommendation for my German Shorthair. she is only 6 months old now but I would like to put in a fence so she can come and go from the garage as she pleases! What do you suggest?

ADMIN – Hi Randy, for a German ShortHair, we’d recommend the SportDog SDF-100A. It is designed for hunting dogs that tend to ignore corrections. This will get her attention and should be a great fit for your GSH. The 1,000 feet of wire that comes with the system should be plenty. Make to refer our Planning/Layouts page to find an appropriate fence layout plan for your needs. You can locate our Planning/Layouts page on the drop down menu under the main heading “Dog Fence Installation” on the main menu bar.

Shirley October 14, 2012 at 9:24 am

I have a rescued adult West Highland Terrier whose mission in life is to hunt for mice, moles, etc. and will ignore me when on a mission. She weighs 14 pounds. We live in a rural community on 3/4 acre with neighbors on all sides. A highway is 2 blocks away and corn fields are 2 blocks in the opposite direction. I’m concerned about her breaking through the barrier and not being able to find her. What do you recommend for a small dog on a mission? Thank you

ADMIN – Hi Shirley, if you’re worried about the size of the collar for a 15 pound dog, I would recommend going with the PetSafe Little Dog fence. Though it’s recommended for dogs 12 pounds and under, it will work great for dogs up to 20 pounds. With great, consistent training, you should expect 100% containment. Our dogs do not run through the boundary.

Dan October 11, 2012 at 3:47 pm

Can you confirm the difference between the former Innotek IUC 4100 and the newly named PetSafe Ultrasmart? Lots of reviews talk about the IUC 4100, but when I select it in the shopping cart , it only appears as a PetSafe Ultrasmart (No reference to IUC4100). Since your reviews seem to treat these as exactly the same, I want to ask the question directly – Did Petsafe make any changes (Positive or negative ) to the IUC 4100, when they took over the product line? Thanks for the great site.

ADMIN – Hi Dan, it is the same fence. The only difference is the branding and it now includes a surge protector. Otherwise, it’s the same fence. Sorry for the confusion.

Amy October 8, 2012 at 4:35 pm

Hi. We have two rambunctious dogs. Both are rescue dogs. One is an English Setter mix (around 60 pounds), the other a Husky/Doberman mix (around 50 pounds). They love to roam the country side and have gotten into porcupines numerous times, as well as skunks, etc. We live in the Texas Hill Country on 11 acres. The terrain around here is very rocky. Which system would you recommend for our dear dogs?

ADMIN – Hi Amy, I would recommend the SportDog SDF100A for both your Setter and Husky mix. The collar offers plenty of correction levels and you can set separate correction levels for each dog. I would recommend upgrading your wire to 14 gauge since you plan to install so many acres and you have such rocky ground.

Luke October 8, 2012 at 12:00 pm

i have a 50 pound lab mix and a 10 pound min pin. I am looking for a system with rechargeable batteries that would work for both dogs. Would this system do the job?

ADMIN – Hi Luke, With such a difference in sizes, you will have to go with a PetSafe system with different collars. I would recommend going with the Deluxe fence with an added Little Dog collar. The downside is that the batteries are disposable, not rechargeable.

trish October 3, 2012 at 9:32 pm

We have a one year old rescue that seems to be a blue heeler/hound mix. He is super sweet and sort of dopey. He will stay in the unfenced yard as long as we are paying attention to him. He is a very muscular sprinter dog that loves to fetch balls. If he happens to see squirrels and deer, he super sprints and ends up anywhere…on the road, neighbors down the street. He likes to go visiting. We are on a quiet road, but off a main and blind curves road. We think we have about a 1/3 – 1/2 an acre to deal with and it backs to a county park. We need a solution! What is your suggestion?

ADMIN – Hi Trish, I’d recommend the PetSafe Ultrasmart PIG00-13619 dog fence. It’s a great fence for Blue Heeler sized dogs. The 3 correction levels should be plenty and the sleek collar should fit nicely. If you have closer to a half acre, you’ll need to bundle in an additional 500 feet of wire with your order.

David Arnold September 27, 2012 at 9:26 pm

I’m looking for a fence system that would have the in-ground wiring, for use at home and a mobile unit to have when taking the pet away from home. Do you offer systems such as this? Thanks, David

ADMIN – Hi David, Unfortunately we do not offer any cross products like you mention.

Maurine September 26, 2012 at 12:51 pm

Hi! We have a 1 year old American Brittany who has taken to digging under our fences and roaming around, which worries me a lot. He is a friendly, well-tempered dog, but is certainly stubborn. He never escapes while we are at the house and awake, but starts digging the moment we pull out of the driveway or, often, when we go to bed at night. What system would you recommend for us? Thank you in advance for your help!

ADMIN – Hi Maurine, for a hunting dog like your Brittney, I’d recommend the SportDog SDF100A. It has the stronger correction levels necessary to get a hunting dog’s focus.

Molly P September 26, 2012 at 12:01 am

Hi, I have a 10 month old labradoodle that we are wanting to contain using a wired or wireless system. My question is, he is a chewer and has been chewing through his cloth harnesses/collars. Could he easily chew through these collars? We are currently using bitter apple sprays to prevent the chewing but I can’t figure out if that would work on this type of collar if it is made of rubber. Thx!

ADMIN – Hi Molly, yes he could easily chew through any dog fence collar. And yes, the Bitter Apple spray is exactly what we recommend as a solution.

Dawn September 21, 2012 at 11:38 am

HI! I am thinking about getting a system. My dog is about a year old and runs out of our yard often. She is about 25lbs. She listens sometimes as long as she is not going after a squirrel or chipmunk. We need to cover our whole yard about 1/2 or 3/4 acre. Which system would you recommend?

ADMIN – Hi Dawn, for a mild tempered dog of your dog’s size, I’d recommend the PetSafe PIG00-13619. You’ll need to bundle in one additional roll of wire to cover 1/2 and acre up to 1 acre.

Ken September 19, 2012 at 1:29 am

Hi I just purchased the Pet Safe Ultrasmart on your website, but now I’m a little unsure if it is the best fit for me. I can always re order if there is a better option. I have a five month old Australian Labradoodle who is fairly easy to train and likes to go outside our yard on occasion. We live on a quarter acre lot in a suburb with no fencing. I would like to contain our backyard and leading up to our house so that she can remain fenced when we are not home. Which option is the best for us? Do you think I should consider a wireless fence? By the way, this is a great website. Very easy to follow.

ADMIN – Hi Ken, I believe you have the best fence option in your hand. A wireless fence is just too unreliable. I think you’ll love the PetSafe Ultrasmart fence.

Chris September 16, 2012 at 5:12 pm

I just moved on 5.4 acres. I am looking to put in a underground fence for my dogs. I have a Scottie, border collie and a lap mixed. What would be the best system for me? What gauge wire do you think I should used?
I have tried a underground fence from petsmart in the past and had no luck with it. It was just a waste of money. Thanks for your help. Chris

ADMIN – Hi Chris, with such a mix of dogs, you’ll want to go with a PetSafe fence. For stubborn dogs/large dogs, you’ll want to go with the Stubborn collar, for averaged tempered dogs 12 lbs and up go with the PetSafe Deluxe collar and for dogs 12 lbs and under go with the PetSafe Little Dog collar. For any installation over 1/3 of an acre I highly recommend upgrading the wire to 14 gauge. This offers the strongest wire to pretty much prevent wire breaks. No matter the system you get, as long as you train correctly, and the collars are set to appropriate correction strengths you should expect complete containment.

Hi, I read some posts to see if I could get a rough idea as to what I am facing. I didn’t see quite the answers that satisfy. I am trying to get a sense as to how much material and cost it would take to enclose my 10 acre site. The boundary is about 2700′, and much of it is dense woods. We have a Great Pyrenees that wants to roam the countryside without me. He doesn’t understand the limits, but I do, and need to rein him in. Appreciate your reply. -Paul

ADMIN – Hi Paul, I’d recommend the SportDog SDF100A for your Great Pyrenees. With all 2,000 feet of wire your cost is $359.75 for 20 gauge. For 10 acres I do recommend upgrading to the strongest wire, 14 gauge. The cost for this with 14 gauge is $739.75.

Jenn September 13, 2012 at 10:37 pm

Hi, We adopted a beagle from a rescue group. He is very loving and sweet (especially with our 4yr old daughter) He is for the most part very well-behaved. However, he is a victim of his own nose and instincts! He finds a way out of our privacy every time I let him out.( even when I stand outside with him …and call him back to me… with a piece of ham in hand!) Sometimes he will come to me after I catch him in the front yard, but I am so stressed. I am constantly worried about him getting hit by a car or someone picking him up. I am worried that his nose will win out even with the fence, he is around 25- 30lbs and we live on approx 150x 100 ft lot and we are thinking of moving in the next year. I thought about a wireless fence because I would like to take him on vacations… to my parents house… or easy re-setup when we move, but it seems like the wired fences are much better. Please help! What do you suggest- thank you

ADMIN – Hi Jenn, I think the wireless is great idea for your setup and need to have a mobile unit.

Kayla September 13, 2012 at 10:44 am

Hi…I am looking for a fence for my lab/brittany spaniel mix. She is very well tempered, good mannered dog, about a year old. She used to stay in the yard, even when we would drive away, she would stay at the end of the driveway. Now she is getting more curious and venturing onto the road. We live in the country and are looking at fencing in 3-4 acres, as she has trained her self to do her business in the field! Also, wondering how the system works with snow coverage? We live in northern Minnesota!! :-)

ADMIN – Hi Kayla, the Ultrasmart PIG00-13619 is a great fit for dogs that are well tempered and good mannered. If your dog had more Brittany Spaniel traits, I may be more inclined to recommend the SportDog SDF100A. For the cold Minnesota terrain, I’d recommend investing in your wire by upgrading it to a professional grade wire like the 16 gauge or 14 gauge. this will offer the best guarantee to avoid time consuming wire breaks. For your property, you’ll need to add an additional 1,500 feet of wire to your order to cover up to 4 acres. As for snow, you will simply turn up the signal width as the snow builds up and then dial it back down as the snow melts in the spring.

Ryan September 11, 2012 at 12:12 pm

Hello, we are moving to a house with no fence. We have a 11 year old Golden Retriever who will stay in the yard and a 3 year old chocolate lab mix that will not stay in the yard. We adopted her and not sure if this system of underground fence will work with her or what her prior owner may have done. Just not sure if this system may bring out some issues if by chance she was abused prior to joining our home. She doesn’t show signs of abuse but you never know. She is very passive but takes off as soon as she has a chance. She will listen and is trainable. We currently have a fenced in yard so this is not an issue. Which system do you recommend we get?

ADMIN – Hi Ryan, for a chocolate lab, the Ultrasmart is a good fence choice. It’s not going to over-correct and you’ll be able to manage the amount of corrections given per training session. We usually limit it to two per session.

Peter September 8, 2012 at 1:39 pm

I have reviewed your site. And am still unsure what system to buy. I am on quite a few acres but looking to only enclose about 1 acre. Should be no problem burying the lines. I have 5 dogs (2 shelties, 2 Pomeranians, and 1 lab). Three of the dogs don’t really wander, but the lab and 1 Pomeranian will (males). The lab is very sensitive and responds well to all training so might not need a bigger charge? We will only use the underground fence when I am in the front with them (or when they “get out”). They already have a fully enclosed back yard with physical fence. What do you recommend?

ADMIN – Hi Peter, your best bet is to go with a PetSafe system so you can mix and match collars. I would recommend going with the PetSafe Deluxe fence and use the collar on the Lab. All the others that are at least 12 lbs can also wear the Deluxe collar. All those under 12 lbs will need the PetSafe Little Dog collar. These fences work in a closed loop. So, if you’re planning to fence just the front yard, you’ll probably need to run the wire up into the gutters in order to suspend the wire high enough along the front of the home so your dogs can travel underneath the signal out of range when the exit and enter the front door. You can see an illustration of this layout by clicking on “Dog Fence Installation” -> “Planning the layout” -> “Backyard only”. (Link is located in the contents box under #4.)

Austin Mahan September 4, 2012 at 2:45 pm

This site is a wealth of knowledge. Thanks for all the useful tips thus far!
I have two German Sheapard/Malamute mixes about 75 and 85 pds. Honestly I am completely new to dog fences and was wondering if you could recommend something for our situation. We are planning on covering both front and back yard, totaling about 1/2 acre. We Definatly need something water proof because they love water/snow and 1-2 days outta the week they are left alone , being when most escapes happen, also should we be concerned about their coat?
One of them was a rescue and is extremely skiddish. I fear that if someone comes in the yard, or of she runs the fence, there would be an issue. Thanks!

Gina September 3, 2012 at 10:36 pm

We are in need of a containment fence for our 7 month old white lab. Deciding on which one is right for us has proven to be a little daunting. We have about 2.5 acres and would like for him to be able to have run of the entire yard. He runs for the neighbors house every time he is outside and will not listen to any commands while he is on the run. We also think we will get a second dog at some point. Something like a Shepard or possibly a Doberman. Which system would you recommend ? Thank you for any suggestions

Cathi September 1, 2012 at 9:12 pm

I have a 3 1/2 yr old 75 lb border collie/australian shepard mix dog that has a mind of his own. I have been using the wireless perimeter wifi system since he was 9 months old and it had been working well. Recently he has found the glitch in the system and is frequently bolting out of the yard. He has learned where the signal drops him and if he runs fast enough it cant catch him. When he does get the correction he retreats back to the house. He has the long prongs and is on the highest correction level of 8. Not sure if its a fit problem or stubborness problem. I do recall when he was a puppy a time that he jumped into an open door truck that was along the fence challenge border. I watched his neck jolt with the shock of the collar but he would not leave the truck to reduce the shock because he wanted to go for a ride (level 8 long prongs). He also did not yelp or show any signs of pain. However he will yelp if you step on his tail. I know I need a new system because this one is not working anymore for him. I am not sure if I need the subborn dog system or the innotek 4100? If he challenges the fence will I be alerted inside like the perimeter wireless fence. I do like that feature so I know where he is and when he does bolt through. He has also gone through 2 collars because of rough housing with playmate – his friend tends to tug on his collar. He is a smart, sneaky, and tricky dog that is very head strong with selective hearing. HELP!!! Which system would best suit my needs.

Jordan August 28, 2012 at 12:59 pm

Hi, I just bought this system but have a question about layout. I need to run the wire across my gravel driveway and it will go directly under where I park my car. Will there be any type of interference from my car or will it affect my car in any way? In other words, will the car and the system affect one another?


Tracy August 24, 2012 at 11:38 am

I am looking at these fences for my son’s Coon Hound. (he just had one get killed in the road) Although, we live in the country, the traffic can be bad. We have about 2.5-3 acres that will need to be covered. He is looking at getting a young dog..any suggestions that you think will help would be greatly appreciated.

ADMIN – Hi Tracy, what breed does you son plan to get? If it’s another Coon Hound we’d recommend the SportDog SDF100A. If it is a dog over 12 lbs and with an even temperament we’d recommend the PetSafe Ultrasmart fence PIG00-13619. For 2 to 3 acres, you’ll need a total of 2,000 feet of wire. 1,000 feet come with the SportDog and 500 feet come with the Ultrasmart. We’d recommend considering upgrading your boundary wire to 14 gauge for the strongest wire available. You can upgrade the wire on any product page in our store.

Bret August 18, 2012 at 8:34 am

I have a question about the IUC 4100 collar. It seems on some other reviews this is not a very durable collar over time, or customers have had to replace multiple times in 1 to 2 years secondary to longevity of battery issues. It seems the Sport dog collar is better. Can you use this with the Innotek 4100 system? I do like the idea of the 9v battery to replace instead of a 100$ collar if it stops working. I however like the IUC 4100 system better.

THanks for the information. Great site

Annalisa August 12, 2012 at 2:10 am

Hi there! I have a 3-1/2 month old Great Dane puppy. She is about 30 lbs now, and her 14″ collar fits loosely around her neck. She is very easily trainable (with treats!), and already knows “sit” and “down” and “crawl” (my daughter taught her that one!), so I think it’s time to get the fence. I’m leaning towards the UltraSmart PIG00-13619. I’m wondering how well the system (collar, mostly, I guess) will grow with her. I’m also wondering if this is the best system package to buy, considering we need 1500′ of wire, and lightning protection would probably be a good idea. Also, for underground fences in general, if there’s a break in the fence (like if a small mammal chewed through it), how hard is it to find where that break is? I’d hate to have to dig up 1500′ of wire to search for the problem area. Thank you so much for your help. This website is a fantastic resource!

ADMIN – Hi Annalisa, for your Great Dane, I’d recommend the PetSafe Stubborn Dog. It is better suited for larger dogs. It will be a fence your pup will be able to grow into as well. It is a cloth nylon collar that you can adjust to their neck precisely. If you were to receive a wire break, you’d need the PetSafe Wire Break Locator which is an item you can purchase in our online store. You will not have to dig up all your wire to locate the break. While, the Stubborn does not include the lightning protection, it is a good idea. I’d recommend adding on to your order.

Brian August 11, 2012 at 9:40 am

We’ve been reading about this (Petsafe UltraSmart) dog fence (and all the comments) and are thinking it’s the one for us. We have a 100lb black lab/shar pei mix, and we’ve recently purchased a new home without a fence. Two questions: 1. How would we account for a two car width driveway in the front of our home? Can the fence be set up to include it as well? 2. Does the fence come with manual correction ability? I’ve seen that some have clickers that work with the same collars — just wondering if this has that option (even if they need to be purchased separately). Thanks in advance.

ADMIN – Hi Brian, you can cross the driveway by laying the wire down into the grooves of the concrete and caulking over the groove. The Innotek 5100 includes the remote trainer for manual corrections.

Peter August 8, 2012 at 12:20 pm

Hi there, I am looking into purchasing the PetSafe Ultrasmart PIG00-13619 as soon as I figure out how to overcome some layout issues. I already have an Innotek-2000 from a few years back that I never took out of the box and I was wondering if I can combine the two wires if the need arises (not sure if 500 ft will be enough yet). I am also wondering what the smallest recommended boundary width setting might be and if the Innotek 2000 collar is compatible to the Ultrasmart transmitter (to possibly use in the case we adopt a second dog). Thanks in advance!

ADMIN – Hi Peter, You can definitely add on to the existing boundary wire. Make sure to match the same gauge of wire though so that the system will see it as full loop. The smallest boundary radius is 3 feet. The Innotek 2000 is not compatible with the PetSafe Ultrasmart fence (formerly the 4100).

scott August 3, 2012 at 4:25 pm

Hi, we have a 9 month old hound mix dog. He is very sweet but very stubborn. We recently bought a new house without a fenced in backyard. Our dog will not stay in the yard. If we get a fence he simply digs and digs along the fence line. Do you recommend an invisible fence and if so, what kind? We would also like to consider one that has indoor capabilities. Our dog is very smart, sometimes too smart. We tried a shock collar but it had no effect at all.

ADMIn – Hi Scott, our dog fence collars operate in a similar fashion to a remote correction collar in that it delivers a static correction in a specific situation. For dog fences, a static correction is delivered when the collar crosses into the boundary zone where the radio frequency is being transmitted. Proper training is the key to successful dog fence containment no matter the system or the dog breed. For your dog, if they have a high tolerance against correction, I would recommend the PetSafe Stubborn fence over the PetSafe Ultrasmart PIG00-13619. However, if they are simply independent but have a normal pain tolerance, then go with the Ultrasmart fence. For the fence collar to properly give a correction, both probes must be making solid contact with your dog’s skin. Without this, nothing will happen and your dog will respond as if nothing has happened. In most cases where it is assumed that there is no effect at all, the culprit is usually a improperly fitted collar. Both the Ultrasmart and Stubborn have indoor capabilities. The Ultrasmart works with the ZND1000 indoor zone and the Stubborn is compatible with the PetSafe Indoor radio fence.

Melissa July 30, 2012 at 9:02 pm

I was looking for a recommendation on which fence would work best for my situation. I have a miniature Eskimo (so I have to consider the thickness of his fur) and a Boston terrier who are both around the 17 pound mark. I also have a Great Dane who is only 10 months and well over 100 pounds. Is there a system that will meet all of their needs? I only need approximately 250 feet of fence. I am looking for a quick solution until I’m ready to shell out the money for a 6′ privacy fence. Thank you…and this site has been most helpful!

ADMIN – Hi Melissa, Yes, for such a mix of dogs, I would recommend the PetSafe Stubborn Fence. I’d put the Great Dane on the Stubborn collar and bundle in two Deluxe collars for the Eskimo and Boston Terrier. The fence comes with 500 feet of wire which will cover your yard nicely.

Don M July 27, 2012 at 7:06 pm

I have a ham radio station I am worried about interference – the collar being activated by the ham radio transmissions and also the fence system interfering with ham radio reception. Can you give me some guidance – like what is the frequency range of the fence systems and are and less susceptible to interference?

Admin- Hi Don,

No worries, the Ham Radio transmitter will not interfere with your dog fence collar. But, it is possible that your dog fence may interfere (cause static) with his Ham radio.

Judy July 10, 2012 at 6:25 pm

I have a fully fenced back yard but have no gate across the single car driveway. I need something to contain my lab from going down the driveway. It is only 18 feet across. What system would you recommend?

Admin- Hi Judy,

If you are only worried about your dog escaping the front gate, than you could simply run the boundary wire across the drive blocking the exit point. You could install the transmitter in the garage and lead twisted wire to the gate area where you will create your loop. Please see our single side diagram under dog fence installations.

Backer's July 8, 2012 at 12:15 am

Have you had any experience with a Keeshond and any of the underground fences? She is a year old, very stubborn, but normally comes running when I call her back to me. The reason I say she is stubborn, is because when I try to correct her she will test me and stand her ground. As as example, I also purchased a training collar is prevent her from jumping up on people and to keep her off the furniture but I had to turn it up to one of the highest settings to get her to react and stop the bad behavior. She also figured out that she could paw at the collar enough to turn if off. I returned it after about 2 weeks of use. She has been the most difficult dog that I have ever had to train. We live in a country neighborhood setting with 4 to 6 acre lots so I don’t think we will have any issues with the neighbors dog fences. Your suggestions are greatly appreciated.

ADMIN – Hi Backer’s, Keeshond’s a double coat which makes it difficult for dog fence collars to be effective. If your Keeshond is over 12 lbs, we’d recommend you go with the PetSafe Deluxe fence and purchase the thick fur probes from the manufacture, PetSafe, where these probes are exclusively sold. You may have to thin the fur with scissors or maybe shave the spot where the collar probes are. Both probes must make good contact with the skin in order to work. Otherwise, they will not feel the correction.

Jay July 5, 2012 at 10:03 pm

I’ve just moved from a fenced in .25 acre to 7 acres with no fences. We have a 6 year old Great Dane and an 8 year old Bichon. I’m planning to only use under ground fencing on about 2-3 acres. I know that the innotek 4100 is the unit that you normally recommend but will this be ok with the size difference of our dogs? Is there another unit you could suggest instead? Or are there additional collars that can be purchased for the 4100 that are for smaller dogs? Thanks In Advance for any advice.

Admin- Hi Jay,

The PetSafe Stubborn Dog system will be the best fence for you because it offers independent correction levels for all the collars on the system. You will use the included collar for the Great Dane and bundle in a PetSafe Little Dog collar for the Bichon, which is the only collar I recommend for a Bichon. The system comes with 500 feet of wire and to cover 2-3 acres, you will need to bundle in an additional 1500 feet of wire giving you a total of 2000 feet.

Rachel July 2, 2012 at 5:02 pm

Hi there. I have a IUC5100 collar without the system. I am interested in purchasing the 4100 underground fence system. I have 2 dogs, if I purchase the IUC4100 system will my IUC5100 collar work with the IUC4100 transmitter? I plan on buying the IUC4100 system and using the included collar for one dog and using the IUC5100 for my other dog. Will this work? Thanks

Admin- Hi Rachel,

Absolutely, the PetSafePIG0013619(IUC4100)and IUC5100 systems operates with the same transmitter box/unit. Therefore, you can use the 5100 collar with the PetSafe13619(IUC4100) transmitter and vise versa. Note: the main difference between the two collar is the IUC5100 collar is compatible with a hand held training remote and the PetSafe13619(IUC4100) collar is not.

Rachel July 1, 2012 at 9:16 pm

Hi there. I have 2 medium sized boxer dogs, a boy and a girl 50 and 70 pounds. The girl is pretty good but if the boy even sees another dog/bike/person he bolts crazy fast out of the yard. If I have a collar on him that isn’t snug he pulls it off and chews it. Both dogs I have to keep on long leashes because as of right now they wont stay in the yard. My subdivision will not allow me to put up a fence and my poor boxers deserve to run free. Will the Innotek 4100 work well for 2 medium boxer dogs? will the collars fit snug? Will this work well for a boxer that bolts out of the yard? I am wanting to purchase this asap if you think it will be a good fit for my kids (dogs). Thank you!!

ADMIN – Hi Rachel, Considering your male boxer’s tendency to bolt, remove loose collars, and chew them up, I’d recommend the PetSafe Stubborn Fence with the PetSafe Deluxe collar for the female boxer. The PetSafe Ultrasmart fence (formerly the 4100) has rubber collar bands on the collar that may be easier for your male dog to pull off and chew up. The Stubborn fence collar is one of our most toughest collars and does deliver the higher correction levels if necessary. It will fit snug on your boxers as well. The collars bands are a nylon cloth with a quick release buckle. You can adjust the collar strap to fit appropriately. As for bolting, the key to pet containment is in training your dogs well. The correction doesn’t contain them, it only refocuses them to obey the boundary rules you’ve trained them to follow. If you train your boxers according to our Training guide, you can expect 100% containment.

mary rose June 30, 2012 at 9:50 pm

Hi, I have rhubarb planted around the perimeter of my back yard and want to keep my two dogs out of it. My backyard is fenced in already with a chain link fence but I want to run an invisible fence around the perimeter about 4 feet in from the edge of my property. I have a westie about 20 lbs and a coton de tulear that is about 13 lbs. Can I run the Innotek 4100 straight from one end to the other or does it have to be a circle? My backyard is about 150 ft total.

ADMIN – Hi Mary Rose, The dog fence will need to set up in a complete loop to operate. If you install the fence 4 feet inside the perimeter, the signal will also be a minimum of 3 feet from the wire. This means that you’re dogs will be keep off the fence at least 7 feet. We’d recommend running the wire at the fence and adjust the signal strength to the distance you want to keep your dogs from the fence.

dgb June 27, 2012 at 6:35 pm

we used to have 2 labs and they were trained with the innotek smart dog system. after they were trained the fence was struck with lightening and destroyed the transmitter. Since the dogs no longer wandered I did not replace the unit. Now we have a 1 year old husky and we need to replace the unit. I don’t know if the wire is intact but I’m hoping that I don’t need new wiring. (we have 10 acres) What would you suggest that I do to proceed? Should I get just buy the unit and collars and then test the wire? Then if necessary just repair/replace the wire? I was thinking of the PetSafe Ultrasmart dog fence (PIG00-13619). Thanks, dgb

ADMIN – Hi DGB, Your unit is still covered under the manufactures warranty. I would contact PetSafe for a replacement transmitter. It should be discounted.

Joan June 27, 2012 at 11:11 am

I’m thinking the PetSafe Ultrasmart fence PIG00-1361 would be suitable for my dog (boxer-husky mix, 65+ lbs). He is very industrious and often successful in his efforts to dig under the existing fence and escape — and never misses his opportunity when the gate is open! Would you recommend this particular model for this kind/size dog? We have 2.5-3 acres to enclose and would zip tie the wire to the existing fence. What kind of wire is used for the fencing: solid copper or strands? (At the hardware store I see both.) I’m thinking I’ll need a LOT of wire!
I have another dog (ridgeback-hound mix, 50 lbs) whom we don’t know whether to train or not on the fence. He is a very skittish, fearful dog, and we think the correction of the collar might not go well. If the collars were independently adjustable, perhaps it would work: a medium correction for the larger dog and the warning vibration for the skittish one. What do you think?

ADMIN – Hi Joan, This is a great fence for your boxer/husky and yes you can definitely attach the wire to your existing fence. Make sure to attach the wire in a way that does not damage the wire insulation. We use insulated staples on a wood fence for example. For up to 3 acres, you’ll need to bundle in additional 1,500 feet of wire with your order to cover your property. We sell 4 wire gauge options, 20, 18, 16, and 14. Both 20 and 18 gauge are solid and the 16 and 14 are stranded. If you decide to incorporate both dogs, I would recommend going with the PetSafe Deluxe with an extra collar so that you adjust separate correction strengths for each dog.

CraigC June 26, 2012 at 1:17 pm

We have two labs 70lbs and Labradoodle. We will be moving to house that have five acres. In reading about theses fences, looks to be an easy and affordable option. The boys mind pretty well and have been trained; one of the labs follows his nose and puts his head downs as soon as door opens. My question is once they go past the boundary; will they be freaked out to come back? Chocolate lab probably will run right thru it and be scared to come back?
Thanks for the love of dogs

Admin- Hi Craig,

Yes, if your Chocolate Labs run through the boundary they would have the same boundary signals upon returning. The key here will be training. Labs are easily trainable with the boundaries; you might only have a run through once or twice initially but with good training on the boundary signals (warnings and corrections), your Labs will understand where the boundary lies and not cross.

Andy June 25, 2012 at 3:08 pm

We have two 10-year-old German short hair pointers, 66 lbs. and 55lbs. We also have a four-year-old Boston terrier/mini dachshund; she weighs 30 lbs. but has a small neck. They have never been fenced in and have never had a correction collar. Our dogs have always been easy to train but don’t know how they will take to this system. This is new to all of us. We have an acre to fence in. We are thinking of the PetSafe Ultra PIG00-13619 (Innotek IUC-4100). But your advice is needed.
1) If you do suggest the PetSafe UltraSmart PIG00-13619 will a small dog collar work with it?
2) During the winter months, will the fence work through three feet of snow?
Thanks, looking forward to your response.

Admin- Hi Andy,

1) The PetSafe UltraSmart collar band is adjustable from 7”- 32”. Typically most 30-pound dogs do not have any issues with collar.
2) Yes, once snow starts to build on the boundary. You will simply turn the signal strength on the transmitter to a higher level. This will allow the signal to project up through the snow covering.

Justin June 22, 2012 at 3:11 pm

I just purchased the PetSafe UltraSmart and am concerned I will not be able to use it for my purpose. I was going to put the wire around the perimeter of the yard and bring it in from the perimeter 3 times to go around my sprinkler heads to keep the dogs from eating them. Also I have a flowerbed that is basically in the middle of the yard so I have in essence to complete circles going. Can I just twist the wire around itself to create a line that the dogs can cross? This way I can connect the 2 circles. I hope this makes sense. Sorry I am not very good at explaining this. Also I have 2 separate entrances into my backyard from the house. How do I make it so that the dogs can come in the house without getting a shock first by crossing the wire?

Admin- Hi Justin,

1) I recommend first installing the boundary wire around the property. To create the signal around the sprinkler heads and flowerbeds, you will splice twisted wire into the closest outside boundary wire than lead it to the sprinklers and flowerbeds areas to create a small loop. This setup will be identical to our exclusion zones layout (see the layout under the dog fence installations tab).
2) Since you are only installing the boundary wire in the backyard, you will need to run the dog fence wire up one side of your house to the gutter or trim level to cross the backside of the house. This will allow your dogs to cross underneath the wire without getting corrected entering your house.

bill June 18, 2012 at 2:05 pm

have a 4 month old english lab. looking at the 4100. how old does the dog have to be to train on the containment fence? i would like to set it up now, but i am not sure he is old enough. thank you, bill

ADMIN, Hi Bill, your dog will be ready to train sometime between 3 and 6 months old. Typically, if you can successfully train him on basic commands like sit and stay, he’s ready for dog fence training.

Joshua Corrick June 17, 2012 at 9:15 pm

Does it come with enough wire to handle an installation for a 2 acre property? Is there anything else I will need to purchase?

Admin- Hi Joshua,
The Petsafe UltraSmart PIG00-13619 come standard with 500 feet of wire that can contain 1/3 acres but the transmitter can contain up to 25 total acres. For 2 acres, you will need 1500 feet of wire. The only other feature you might need will be twisted wire. The twisted wire will create a dead zone between the inside transmitter and the outside boundary.

Dan Martin June 13, 2012 at 9:55 am

What is the difference between the Petsafe Deluxe Little Dog fence and the Petsafe Elite Little Dog fence? We have a 7 month old Coton de Tulear/Shih Zhu hybrid puppy. Breeder said he would get 10-12 lbs when full grown. Am on the bubble between getting one of the PetSafe systems with the smaller collar or the PetSafe Ultra PIG13619, because of the rechargeable battery. Any advice?

Admin- Hi Dan,

You are going to limited on which system you can use based on the oton de Tulear/Shih Zhu neck size. If the neck on your oton de Tulear/Shih Zhu is at least 8 inches around, than the PetSafe Ultra PIG13619 collar will fit. However if his neck is smaller, your best option is going to be the PetSafe Little Dog system. We are not aware of a PetSafe Elite Little Dog system. The retailer that is advertising this system could simply be adding a small feature (lawn staples or twisted wire) to the package than changing the name. The transmitter and collar will still be the same.

I am ready to order the electric fence but I need to know what is a boundary width listed in the dimensions refers to. Does this refer to the area between the edge of the fence installation and the correction?

Admin- Hi Beth,
The boundary width is the distance at which the collar receives the signal from the physical boundary wire. Example: If you have the boundary width set on 6 feet. As your dog approaches the boundary wire, the collar will receive the warning tone at 6 feet away from the physical boundary wire.

Zack May 27, 2012 at 3:55 pm

Great and helpful site! I’m wondering if the PetSafe Venture Series Little Dog 400 Yards Add-A-Dog collar is compatible with the PetSafe UltraSmart PIG00-13619 system, for our second (small) dog (8 lb terrier/Chihuahua mix)? If this collar fits it seems to be a better option than the ‘in-ground deluxe little-dog receiver’ because of the rechargeable battery. Thanks.

ADMIN – Hi Zack, Unfortunately, there isn’t a compatible PetSafe collar for the Ultrasmart fence. The reason is that the Ultrasmart fence came over to PetSafe from the Innotek brand of products.

Randy May 27, 2012 at 1:00 pm

Have a 1 year old Akita. They have 2 coats and huge neck. 23” Looking at the iuc4100. Will this be a good fit? Also, when they break the barrier, for whatever reason, what is the best way to get them back inside?

ADMIN – Hi Randy, This is a great fence for an Akita. With the thick undercoat, you’ll need to probably purchase the thick fur probe from PetSafe and then also trim the fur a bit with scissors around the area where the collar will sit on their neck. The collar band will fit their neck.

Dog’s that break through the boundary can be brought back by removing their collar. A dog that breaks through either has a improperly fitted collar and the probes are not contacting the skin, or the dog needs more training. Make sure that breaking the boundary does not become a habit. Re-training becomes more difficult the longer they are allowed to leave.

We have about 1200 feet of 12-gauge twister wire encircling our 3-acre lot. We have about 150′ twisted wire getting us connected to the transmitter that is located in the garage. We have cross all utility lines at right angles and are not aware of any metal near the boundary wire and are at lease 3′ away from any metal at the transmitter location. We have an RF125 transmitter and have noticed that when the transmitter is set at B or C and the dial is turned up over 8 the boundary field expands to over 70′ from the boundary wire. At setting 10 the whole property is receiving the signal. Is this normal for this transmitter, or is something amplifying the signal? If it is amplification, what could be causing it?

ADMIN – Hi Jean, it sounds like you are receiving amplification from one of your utility lines. Crossing the utility lines at a right angle minimizes the interference risk but does not mean it still cannot happen. I would turn down the boundary signal as far as possible and check the width again.

Holly May 20, 2012 at 9:50 pm

We purchased the Innotek 4100 system from you, and installed it on an existing fence, around approximately one acre. We have had it almost a year, and it is great. One of our four dogs was always getting out and running away, and now she never tries to get out. However, now I regret that I did not get the collar with the remote trainer, because if she ever gets out a door, she’s gone and no one can catch her for hours. That seldom happens, but it only takes once. She just knows she is free, and will not let anyone catch her. Is it possible to buy only the remote trainer portion, because we do not need the wire, etc. Or is it possible to buy a different collar that will work for both the fence and the handheld remote?


Admin- Hi Holly,

There isn’t an easy upgrade option to get the 5100 collar and remote. While, we sell the 5100 collars, we do not have the remotes in stock. Unfortunately, the remotes are only packaged and sold with the 5100 fence. Now, you may be able to locate these remotes on the web, but I imagine you’d have to locate a site that sells refurbished equipment.

Tracey May 20, 2012 at 4:17 pm

Can you tell me how high the wire has to be to not affect the dog. We use the back of our house which has both sliding glass and a back door for exits onto a raised wooden deck. If we ran the wire “over” the doors (approx 8 feet) is that sufficient to keep the signal away? Also, if the main component is plugged “INSIDE” the house, does it affect the dog inside. The location we would place it inside is in the same room the dog sleeps in? I would appreciate any answers before we decide to purchase. Thanks.

Admin- Hi Tracey,

1) The minimum boundary distances projecting off of the wire is 1-2 feet and the maximum is 10-12 feet.
I am not sure that applying the wire above the door will give your dogs enough room to pass underneath. I recommend installing the wire at the trim or gutter level if possible.
2) The transmitter inside the same room could send a signal to your dogs collar. You will want to run twisted wire off of the transmitter to kill the signal around the transmitter. However, you will want to take the collar with the tester and test inside the room to verify that there is no signal.

Brian May 19, 2012 at 4:41 pm

I enjoy seeing all of your replies to comments. My question is that I only need to protect my front yard. I have had my dogs get out of our garage and the backyard, however, only one dog is the problem in that when he gets loose he is running all over the place and does not listen to any type of commands. In this situation, would I be best off placing the fence to go in front of the fence and garage, or would I be better giving him some room and place it at the edge of the yard against the street? I would be using this on one large dog and one small dog, and I saw that I could do the resistor hack which would not be a bother for me.

Admin- Hi Brian,
1)If you are only worried about your dog escaping the front yard, than you could simply run the boundary wire along the front of your property blocking the road. You could install the transmitter in the garage and lead twisted wire to the frontage road than create the loop separating the road and your property. Please see our diagram for signal sided boundary under the Dog Fence Installations tab.
2) The resistor hack works really well for smaller dogs. The resistor will reduce the amount of correction by 50-75 percent.

Steve May 2, 2012 at 5:07 pm

We have a heavily forested one acre rectangular property. How difficult is it to bury the wire through a forest, trees, etc, as well as crossing a concrete driveway ?

Admin- Hi Steve,

The wire only needs to be buried 2-4 inches in the area that you will be mowing. For the rest of the loop through the forest, you can install the wire on top of the ground and take a garden rack to rack some natural ground cover over the wire for added protect. You will want to install the wire with lawn staples as well to help the wire stay flush to the ground. For your the concrete driveway, the easiest method to cross will be to install the wire inside the expansion joint.

Cheryl Hazle April 24, 2012 at 10:51 am

Hi – I own a German Shepherd and a Basset Hound (both are 2 years old). We live on 2 acres and need to install an underground fence. Should we go with the Stubborn dog system or the Innotek 4100? Also, we have a pool where the dogs like to take an occasional dip in the summer. Thanks!

Admin- Hi Cheryl,

We would recommend the Stubborn Dog for your Shepherd and Basset Hound over the 4100 since your hound will be smaller. You tend to need the additional correction levels to refocus hunting breeds and the Stubborn dog system will give you the flexibility to adjust the correction amounts for each dog. Plus, the Stubborn collar is really waterproof which is another great reason for you go with this fence.

Kate P April 22, 2012 at 9:00 pm

We have a 4 month old German Shepard/mix and are looking at possibly getting the Innotek 4100. We have a flat rectangle lot but in order for the dog to get to the yard, he has to go through our large driveway. Is this unit possible to use so that we can just let him out the backdoor? We will be happy to join the waitlist, as he will be a good age to start in June.

Admin- Hi Kate,

You will be able to install the boundary wire around the property so that your German Shepard can enter and exit the backdoor. Please see our diagram page underneath the “Dog Fence Installation tab” on the home page. We will add you to the waitlist.

Chuck Ahnert April 17, 2012 at 6:35 pm

I’m considering purchasing one of the fence systems that you sell, but I have a couple of concerns. Once I train my dog the boundaries in the yard, and he begins to respect the boundaries and not go near them, won’t he be afraid to cross the boundary in my front yard when it’s time for me to take him for a walk on a leash? Won’t he be afraid to cross the line because he’ll think that he’s going to get a shock? Doesn’t he get confused that when he is loose in the yard with the collar on and he gets too close to the boundary he gets a shock, but other times I lead him across the boundary with the leash and he of course does not get shocked because the collar is off? Also, how easy is it to take the collar on and off? Does the collar come on and off quickly and easily? Thank you for your help with my questions.

Admin- Hi Chuck,

1) The key is going to be in the training. For the first couple of months try to keep everything consistent and don’t walk them through the boundary. You could take off their correction collar and either drive your dog over the boundary or carry your dog over the boundary if possible so they don’t get confused. If you stick with this same routine going forward, your dog will soon learn that there is an exception to their general boundary rules – when they are leashed and accompanied by you, they may cross the boundary.
2) The IUC4100 and IUC5100 collars have a quick release buckle and a typical buckle (like a belt).

Dan Jordan April 16, 2012 at 3:00 pm

We are considering the Innotek 4100 for our remote property where there is no utility power. Will this device work with the 12 volt battery-based A/C inverter we are currently using for our other A/C-powered stuff?

Admin- Hi Dan,

The Innotek 4100 system will work if you have a DC-AC inverter.

Kim April 13, 2012 at 9:58 am

I bought the smart dog in ground pet fence, now I am hearing it is not so great, wire breaks easy and collars are to small, what if I buy 20 gauge fencing wire and connect it to the unit it should still work right??

Admin- Hi Kim,

The Smart Dog is a poor quality system. You can upgrade the boundary wire to improve the quality of the cheap wire that comes standard with the system; however, the systems transmitter and collar is cheaply made and will still be unreliable.

John D. April 10, 2012 at 5:14 pm

Just when we thought we had done everything right, our neighbor gets a new dog! Now our Malmute can no longer resist running over to play with his new ‘buddy’. We can’t seem to figure out why he is not getting corrected when he approaches and bolts through the boundary at times. This has been happening too often.

He clearly respects the sound of the transmitter because when we try to ‘retrain’ him by walking him around the yard, he will not go near the boundary (he will lay down and refuse to move). In other locations, the sound of the beep on the collar will stop him from moving. So now he sits in our yard in a very small radius and will not even move into the larger safe zone to play with us. However he regularly seems to know when it’s ok to ‘bolt’ through the boundary (when his new buddy is out). Is is possible that if he runs through the boundary very quickly, he will not get a correction?

Also is it possible that the collar shuts off if he has been sitting near the boundary zone for long periods?

Our neighbor did install their own electric fence (a different brand) is it possible that their system could be interfering with ours along the common boundary?

ADMIN – Hi John,

There are a number of possible explanations, but I think the most likely is that you are getting cancellation along that common boundary.

When two dog fences are close together and have lines running parallel (within 12 feet), they can cancel each other out. The way to test this is to take your collar and walk it through the common boundary and see if it works consistently (beeping and shocking). If it isn’t working, have your neighbor turn off their fence for a few minutes, and then see if your collar starts working. If this is the problem, you will either have to move your wires further apart, or one of you will have to switch to a dual frequency system that will let you avoid interference.

The other likely possibilities are that your collar or transmitter are defective. Or that the collar is not properly fitted, so the dog is not feeling the correction. But, my first bet would be on the interference.

Hope MacIntyre April 9, 2012 at 4:52 pm

HI there, first do you ship to Canada and second our winters are -40 F at times, will wrapping in insulation help keep the transformer warm enough. Also I have a Pyrenees who very protective and territorial, will a stubborn collar be enough as he also has a very thick coat? Thanks so much, Hope

ADMIN – Hi Hope,

Wrapping the transmitter in insulation works to keep the unit warm, and should help in the extreme cold. Keeping the transmitter out of the elements is however the main consideration, so as long as it is sheltered, you should be in good shape.

The PetSafe Stubborn collar should be fine with a Pyrenees. However, having a stronger collar does not help you at all in terms of getting the collar fitted. The collar prongs need to contact skin or the collar will not work irrespective of it’s strength. To get a good fit, you may want to thin out the hair where the collar probes touches the skin – this can be done with regular scissors. You also want to part the hair and move it out of the way when you are fitting the collar.

We do not ship to Canada.

Kim April 8, 2012 at 10:38 pm

I have a 25 lb Westie. I have been looking into the 4100 but have also now seen the PetSafe Deluxe In-Ground Radio Fence System. I noticed it has built-in lightning protection vs needing to buy a separate surge protector for the 4100. The collar on the 4100 looks sleeker to me than the other. Can you tell me pros/cons of one over the other? I’m really leaning towards the 4100 but am open to other options. Thanks!

ADMIN – Hi Kim,

BOth the Innotek 4100 and the PetSafe Deluxe are good systems, and both will work well with a Westie. The Innotek collar looks sleeker, but both collars are similar in size and weight. The big difference between the two systems is that the Innotek collar is rechargeable. And the PetSafe collar uses a disposable PetSafe battery (costs around $5 and lasts 2-3 months). The Innotek also has a few extra features like the “collar fit check,” but the PetSafe Deluxe is a little cheaper to compensate.

For both the PetSafe Deluxe and the Innotek 4100, the lightning protection is an optional extra ($40). The only systems in which it is included are the PetSafe Little Dog, and the Innotek IUC-5100.

Monica March 29, 2012 at 4:36 pm

Hi, we own a three year old Siberian Husky and we live in the woods with ocean front property. This is strange for a husky but he loves to swim, so what i would like to know is which system would be the best for him? Since he loves the water we want him to be able to go swimming but also have the best system to keep him from running away. We have had other huskies that were taken by wolves so we do not want this happening to this guy.( it is way to heart breaking!! ) Thank you

ADMIN – Hi Monica,

The challenge with giving the dogs open access to the ocean, is that some dogs will realize they can swim around the boundary. In terms of system, there are plenty of good waterproof systems that the dog can swim with. Two good systems for a swimming Husky would be the Innotek IUC-4100 and the SportDog SDF-100. Both are excellent systems and waterproof. The Innotek has a rechargeable battery, and a smaller collar. The SportDog is a little cheaper and best of breed waterproofing, but the collar is a little bigger and it uses a disposable battery.

jim March 29, 2012 at 7:51 am

several questions…
-we have had the dog, aussie herder mix, for 1 year, he is 2.5 years old, is it too late?
-I am a fireman, I work every third day and the dog goes to my mothers, I can take him out in the morning, but he will not be home till 6:30-7 pm. At her house he is on a tether, will this mess up his training? Would it be better to train him in July when I have time off?
-I will place the one boundary in the woods on the side of the hill at the back of the yard. He does not routinely go there, but I would like him to have some access. How do I train him on this boundary without leading him there?
-when having him outside in between training sessions, can I put him on a line? Right now he is free to go, I just have to keep an eye on him.
Thanks, Jim

ADMIN – Hi Jim,

(1) Not at all. Contrary to popular wisdom, there is no problem teaching an old dog new tricks. All dogs are equally motivated to avoid to avoid the correction. The only issue comes with very old dogs that have lost hearing – but that does apply here.

(2) You need to do at least two sessions a day. If you can’t do some training in the morning and the evening for at least two weeks, I would wait until July.

(3) You can place flags around the boundary, and the dog will learn to generalize. So even if you can’t train him on a specific spot, he will learn to recognize that flags represent a boundary.

(4) Yes. You can and should contain him during the training so that he cannot cross the boundary. If he can cross the boundary between training sessions, it undoes the training. If a line keeps him in the yard, that will work well.

Dan March 27, 2012 at 6:33 pm

We have a lake house and want to buy a system that will allow the dogs to swim for an extended period of time. I saw something that noted this system is only good for temporary immersion in water… we were going to buy this one, but we really want to make sure that it is something safe for swimming. Thanks, Dan

ADMIN – Hi Dan,

The Innotek IUC-4100 is fully waterproof and can handle full immersion. It is safe for swimming.

Shane Simmons March 26, 2012 at 10:22 am

I don’t believe that my ultrasmart collar is holding a charge. The books says that the collar should last for 2-3 months before charging. I have to charge mine about 1-2 times a week. I don’t leave the collar on my pitbull. I put it on him when we go outside and take it off when he comes in. I leave it laying on a table by the door so its easily accessible. What would cause the collar battery to drain down? And when I do charge it, is it ok to leave it on the charger for longer than the 2-3 hours charging time or will it damage the battery?

ADMIN – Hi Shane,

Our experience, is that once trained and no-longer testing the fence the collar should only need charging about once a month. 1-2 times per week seems too often. I would check that the place where you are leaving the collar is not near the transmitter or boundary line, otherwise this may be triggering the collar and draining the battery. I would also check that the dog is not frequently challenging the fence (if so we need to do a bit of retraining and check that the collar is correctly fitted). If neither of those two is the issue, contact Innotek and swap the collar for a new one, because something is wrong with the collar.

There is no harm in leaving the collar on the charger beyond the 2-3 hour charging time.

Doug March 25, 2012 at 10:56 pm

My neighbors have an in ground wire fence system (I don’t know the specific brand). Our dogs like to play with each other frequently. Can two systems overlap? In other words, could there be a small loop from my system (if I were to purchase Innotec 4100) that goes into my neighbors yard (obviously would need their permission) that would allow the dogs to still be able to play with each other?

ADMIN – Hi Doug,

Unfortunately since your neighbors already has a wired systems installed, the IUC4100 will not work if you install your boundary wire close to theirs. When the Innotek IUC4100 boundary wire is installed close to another in-ground system boundary wire, the IUC4100 boundary will not be active. The two fences will case interference’s with one another and you would have to separate the two wires by 10-20 feet. The only fence option that will allow you to install close to your neighbors boundary wire will be the Perimeter Technologies systems. The Perimeter Technologies system offers a frequency change option that will allow you to off set your neighbors signal and avoid interferences. However, you still would not be able to over lap the two boundary wires.

Lori March 23, 2012 at 11:57 am

We live on a farm and our little dog has developed a fascination with a dog a couple of miles away. We want to use your fence for our property but her determination to be with this other dog is strong. Will she go through this fence regardless of the unpleasant stimulation?

ADMIN – Hi Lori,

With the training, you should be able to achieve complete containment, even if her buddy is on the other side of the fence. If you are particularly concerned, it will help if you borrow the neighbor’s dog and incorporate them into the third stage of the training, although this is not necessary. Also since, you have a nice large property, I would set the dog fence boundaries to be wider than usual (say 10 feet on either side of the boundary wire)

stacy March 21, 2012 at 4:35 pm

I am thinking of purchasing the 4100 system or PetSafe stubborn for my 105 lb Airedale and his sister which is approx 80 lb. I am guessing from the reviews that I would have to have individual correction with the weight differences, Is that correct? Both dogs know the beep correction signal and they are already good with a correction difference of 1 on a remote. Another issue is with figuring out how to place the wired section along a neighboring yard without/with correction due to the fact that all dogs meet at the fence on occasion. Do I have to place the wired section along the top of their fence with connectors and then set the boundary somehow? Any suggestions would be appreciated.

ADMIN – Hi Stacy,

1) For your two Airedals we recommend the PetSafe Stubborn/Large dog system. The Stubborn dog collar is designed for a larger breed of dogs and are very durable. The collar will hold up to playing and “ruff housing” much better than most collars.
2) You will be able to set the signal strength projecting off of the boundary wire. If you do install the boundary wire on top of the fence, you will set the signal strength lower so that your Airedals do not receive any signals at their collar level. However, the only way to open the fence section up so that your dogs can approach will be with our Gate layout. Please see the diagram under the installation tab on our homepage.

Brandy T March 20, 2012 at 9:43 pm

Hello. We have a very large yard and are looking to close in between 1.5 and 2 acres. Is it easy to connect additional rolls of wire? And how many can you string together? Thanks!

ADMIN – Hi Brandy,

Splicing the wires together is easy. You just strip a bit of insulation off the end of each wire, twiste the wires together in the supplied wire nuts, and then seal the wire nut in a gel filled capsule. I can’t imagine it taking more than 2 minutes per splice.

The total amount of wire depends on the system. For the Innotek 4100, it is around 5,000 feet of wire (10 rolls).

Ashlyn March 19, 2012 at 12:40 pm

I have two small dogs (5lb. chihuahua and 15lb. yorkie) and will soon be moving to a farm with several fields with existing high tensile electric fence for cows. Our yard will border the fence in several different areas; my questions are can the wires for this system be connected at any point to the bottom wire of the electric fence or can this wire be stapled on under the bottom wire on the fence posts? Will the electric fence interfere with any of these systems when both are on? Also, I’m not sure what the best system would be to go with; this Innotek IUC 4100 or the Pet Safe Little Dog or Stubborn? I, like many others on here, am also not a fan of having to buy batteries every two months so I would prefer rechargeable but it doesn’t seem like that is an option for my chihuahua. I would also be interested in the indoor zone products I saw, but don’t have to get them – not sure what systems would have that option? I want to be able to leave the dogs outside all day while I am at work when it’s nice outside so I want to make sure I have the best system I can get. Any help would be greatly appreciated!

ADMIN – Hi Ashlyn,

I would not connect the dog fence to the electric fence wire, but you can attach the wire to the same fence post instead of burying it. You should not get any interference between the two system, they work in different ways.

With two dogs of that size, the PetSafe Little Dog Fence is your best bet. The collar on the other systems would be too big and too heavy, and the correction levels too strong for the Chihuahua. The PetSafe systems has an indoor pod similar to the Innotek, except their pods are not wireless and need to be plugged into an electrical outlet.

Joanne G. March 19, 2012 at 1:39 am

Hi there, We have a large Alaskan Malamute and two smaller rottie/lab crosses. The fence is mostly required for the Malamute. Which fence system would you recommend for him? And would this system work to contain him. We live on a farm and need to contain about 1/4 acre. Thanks for your response in advance.

ADMIN – Hi Joanne,

A good system for the Malamute would be the Innotek IUC-4100. The collar fit test that is built into the 4100 collars is very useful for getting the collar properly fitted with the dog’s thick undercoat. With the training, I would not expect any problems getting him contained. If you needed to add the other two dogs at a later date, that system would also work well.

Big T March 18, 2012 at 8:12 pm

i have a 3 year old 65 lb lab that I would like to keep contained on my 5 acre lot. I live on a large pond and my lab swims all the time. I am not concerned about him swimming to the other side but would like to give him the chance to swim pretty far out to get his toy and back without issue. Is water an issue??
Also, the lit comes with 1000 feet of wire that is good for 1 acre correct? If I need enough for my 5 acre lot do I need another kit or just another roll or two of wire? Thanks!

ADMIN – Hi Big T,

If you use one of the systems (Innotek 4100, Petsafe Stubborn, SportDog SDF-100A) with a waterproof collar, the swimming with the collar will not be a problem. The SportDog SDF-100A has particularly good waterproofing and would be my top choice for your lab in this situation.

Most of the systems come with 500 feet of wire (the SportDog is the exception and comes with 1,000 feet of wire). Additional boundary kits (including wire, connectors, and flags) are available for $30 per 500 feet. To cover 5 acres, you need about 2,000 feet of wire total.

Jon March 18, 2012 at 6:12 pm

I have a Lab #50 and min schnauzer #20 both sized for 4100. would it be best to use two colors and train together or one collar and train individually?

ADMIN – Hi Jon,

During the training phase, the two dogs can happily share a collar, because you will be training them individually. I would avoid training them at the same time, because they tend to pay too much attention to each other, and not enough attention to the trainer. While one dog is training, put the other dog in the house or somewhere else out of site.

Once you are finished with training and letting the dogs out into the yard off leash, they will each need their own collar.

FYI – if you use the 4100, ask us for the resistors so you can lower the correction level for the Schnauzer – he is likely to require a lower level than the Lab.

Juli March 17, 2012 at 11:12 pm

I am considering the Innotek 4100 for my 2yo shepherd/doberman mix on 2 acres. I think she has a normal sensitivity to pain–‘think’ being the operative word, here. I know she has a strong prey drive. Whether she sees a deer or picks up the scent of vermin in deep grass, both are irresistible. I get what you would do at the tail end (no pun intended) of training, but how would that work for deer that like to hang out with in her safe area? Could I expect that with proper training, when she spots deer after they are already in her safe zone and takes after them, once they (the deer) cross the boundary she would stop?

With regard to ” laying a scent trail through the fence”, how is that done and with what?

ADMIN – Hi Juli,

With the training, and a nice wide boundary (on 2 acres, you should have space to be able to make the boundary 10+ feet wide) you should expect to be able to get even a high prey drive dog to stop and turn even once they are in full chase. If you can get the dog on a long-leash and have this happen a couple of times in training, this would be ideal. You may be able to tempt the dear out by leaving some feed nearby for a couple of consecutive days.

Hunting stores sell animal scents that you can spray along the ground to create a ‘scent trail’. This is useful in advanced training to avoid (FYI – avoid purchasing ‘natural’ animal scents, the way they are collected is not very animal friendly)

Dave March 12, 2012 at 7:31 pm

Why did Innotek stop packaging the twisted wire and surge protector with the IUC-4100. It doesn’t make any sense. The IUC-5100 comes with an extra feature, a remote, a lightning protector, and the twisted wire for just the cost of adding the lightning protector to the 4100. Not to mention that according to my research the 4100 and 4200 are the same exact thing electronically and were priced the same but, the 4100 lacks the twisted wire and lightning protector. Are the electronics in fact the same? Is the 5100 receiver significantly larger than the 4100 unit to the point that it would make a difference to a large breed dog (80-100#)? I just can’t justify buying the 4100 and having to pay more than the 5100 when adding the extras for less features. It makes no sense!

ADMIN – Hi Dave,

You have it right. Oringially, the 4200 was the same as a 4100 but with the twisted wire and lightning protection included. We don’t know why, it was discontinued, but around 3-4 years ago it was discontinued.

The 5100 collar is around 50% bigger than the 4100 collar. So if you have a big dog, the 5100 is a good deal — you effectively get the remote trainer, twisted wire, and lightning protection for $40 extra. The dog fence functionality on the two systems is identical.

Perry March 9, 2012 at 7:44 pm

(1) Can you use the Sportdog collar with the IUC 4100 or 5100 so that you can have different correction levels?
(2) Also I like that the 4100 has battery backup. Optionally, can a backup battery be connected between the charge adapter and the Sportdog Transmitter? It would be bad news if someone drove up with the fence off.
(3) Does the 5100 battery have to be returned for replacement?
Out of all the systems I’ve looked at, none of them have the optimum system. Thanks

ADMIN – Hi Perry,

(1) The SportDog collar won’t work with the Innotek systems. Unfortunately the only collars that will work with the Innotek 4100 system, are the SD-2100, IUC-4100, and IUC-5100 collars.

(2) You could connect a battery backup system (like an Uninterrupted Power Suply – UPC) to the transmitter plug for the SportDog Transmitter.

Alternatively you can get different correction levels using the Innotek, using the resistor hack trick.

On a practical level, unless power outages are frequent, battery backup is not that important because once trained the dogs will rarely test the fence and so don’t figure out when the system is not working.

(2) The Innotek IUC-4100 and IUC-5100 collars do need to go back to the factory for the battery to be replaced. Batteries should last at least 5 years. It costs around $30 if you are outside the warranty period.

We have two Jack Russells. Both like to escape and chase rabbits and squirrels. It seems like when they are after something, pain and injury will not deter them. Do you think the Innotek 4100 would be strong enough? They weigh 18 and 21 pounds.

ADMIN – Hi Jan,

The Innotek should be plenty strong, with Jack Russells – you would typically use the low setting, never more than the medium. The correction, along with the training will stop even high prey drive dogs in their tracks. The correction sensation is very odd to dogs (and humans), it is much more startling that painful, and it is enough to redirect their attention away from the stimulus (like a fast moving critter) and back onto the fence. I think you will be pleasantly surprised at how effective it is.

Craig March 7, 2012 at 7:12 am

Ok, I have not noticed this question answered yet. I have about a 50 lb lab, he’s a roamer and have had problems with one neighbor. We have a large creek close to the house and in the summer he likes to lay down in the creek and keep cool, my question is: Can I run the wire through running water and have it function normally without interference?

ADMIN – Hi Craig,

You can run the dog fence wire through water and it will function normally. It helps if you run the wire through a protective pipe (like hose pipe) and staple the wire down tot he creek floor to protect it from debris, but neither of these are necessary for it to function.

Wayne March 6, 2012 at 9:32 pm

What would you recommend for a Karelian Bear dog. We are getting a pup in May and are exploring electronic fencing possibilities.

ADMIN – Hi Wayne,

With a Karelian, you would be well served with one of the stronger systems like the PetSafe Stubborn. Karelian have often been bred over the years to be indifferent to pain, and so need a stronger system to redirect their attention, particularly once their prey drive or protective instinct has kicked in. The Innotek you are looking at is probably strong enough, but I would rather play it safe and get the PetSafe Stubborn just in case those higher correction levels are needed.

Of course, we would wait until the dog is 6 months old to start training. Younger than that, and they don’t have the maturity and attention span to respond effectively to the training.

Michelle March 5, 2012 at 8:16 pm


I have a 6year old male Doberman he weighs 65-70 pounds. We just moved to a new house the end of last year that is on 41/2 acres, we would like to install underground fencing for our dog on 11/2 acres of that around our house. He stays on our property for the most part but we live on a 50mph road I am do not want to take any chances. Do you think this would be a good system for us? I have looked at Invisible Fencing but the price is so high I am not sure they value is there for the cost? We already have the ditch dug and ready to go. He is our only dog so I am not concerned with being able to set the fence for several dogs.

Also dose this kit come with any twisted wire?

Admin- Hi Michelle,

The Innotek 4100 system will be a perfect system for your Doberman. The system comes 500 feet of boundary wire and to cover your 1.5 acres you will need a total of 1500 feet. Unfortunately the Innotek 4100 system does not come with any twisted wire.

Julie March 2, 2012 at 6:20 pm

I plan on purchasing the Innotek IUC 5100 for my doberman pup.
My question is this: If I use pvc pipe to protect the wire across the driveway, do I need to worry about water collecting in the pipe and freezing: causing damage to the wire?
Gotta love winters in the midwest!

Admin-Hi Julie,

A little water freezing inside the PVC pipe will not be a problem; however, if the pipe is full of water it could harm the wire. To prevent water from entering, you could caulk both ends of the pipe around the wire with a sealant. This would ensure that the wire would be safe.

Monica March 1, 2012 at 9:01 am

We are interested in purchasing the Innoteck 4100. We have 2.58 acres and have many moles on one side of the property. Do you think moles will eat through the wire? What gauge of wire would you suggest?

What is the difference between twisted wire and the regular gauge underground wire. ? So for 360 degrees of access around your house—you would use twisted wire from your box to the perimeter? Would you use only twisted wire in the spot from your box out to the perimeter and then use regular wire for the perimeter? Maybe you can explain this more.

Sure appreciate this website and all the feedback you provide!!!!! Thank you in advance. Monica

ADMIN – Hi Monica,

Moles can chew through the wire. For some folks with moles it almost never happens, for others it can be a chronic problem. If you think it is going to be an issue, there are a couple of strategies you can employ to minimize breaks. You can run the wire above ground (on a stakes or a convenient fence) along the affected area. You can bury the wire in a protective sheath, like sprinkler pipe. Or you can use thicker wire as you suggest. With 2.6 acres, you will need around 2,000 feet of wire, so upgrading to something stronger like 14 gauge will add (around $300) to the cost.

The twisted wire is used to create the non-corrective link from the box out to the perimeter. You run the twisted wire from the control box out to the perimeter, at which point you connect the single boundary wire to one of the twisted wires. The boundary wire loops around the property and connects to the second twisted wire.

This Twisted Wire page in our Installation section can explain further and has some good illustrations.

Paul February 28, 2012 at 6:16 pm

I was reading some of the reviews and notice that the collars tend to have charging issues and since it is a sealed unit you are forced to buy an entire collar versus just replacing the batteries. At $100+ each that would get a little pricey. Any suggestions? Thanks

ADMIN – Hi Paul,

We have not seen too many issues with the collar not holding a charge; however, if you do experience issues with the collar or transmitters. You will receive a full one-year warranty followed by a limited lifetime warranty through the manufacturer if you purchase your fence from an authorized retailer like us; therefore, you will always be covered if any issues arise. The last time we checked the replacement collars through the limited lifetime warranty is between $30-$40 to replace.

David February 27, 2012 at 6:34 am

I was thinking about attempting to power this unit in a remote pasture using a solar battery charger, a car battery, and a power inverter. We only go out there occasionally, so it will not be operated full time. I would also be building a weatherproof enclosure for the electronics and a place to mount a small solar panel.

Given that the battery back up on this system uses 8 AA batteries, do you think that this method would work to power the system for only a few hours a day and a couple of days a week? I can not find the input voltage and amperage requirements anywhere to confirm my idea.

ADMIN – Hi David,

I don’t know much about using solar power. But, if it helps the input voltage and amperage are as follows: 12 volts (DC) @ 200 mA (milliamps). If you can get that input voltage, you will be in good shape.

Pam February 17, 2012 at 9:12 pm

I have a husky and an Akita who like to run off. We have not quite 2 acres that we want to fence in. Looking at both wire and wireless. What would be our best option? Would the wireless cover 2 acres? Also already have electric fence for cattle around this area. Can the wire be put on the electric fence post?

ADMIN – Hi Pam,

We would always prefer to use a wired fence, it produces crisper boundaries that make training the dogs easy. The wireless fences have boundaries that wander – the inconsistency makes training harder. For two Akitas, the Innotek IUC-4100 would be a good choice. It could comfortably handle the two acres, has a rechargeable collar, and has a collar-fitting feature that makes getting the collar on a long-hair dog like an Akita easier.

If you have electric fence posts already in place, you could certainly mount the dog fence wire on those posts.

The wireless fences have a variety of ranges. Our top choice, the Havahart radial could cover 2 acres.

Heather C. February 16, 2012 at 11:54 am

We have two dogs where and how much is it to purchase a second collar? Do you need to hook anything up differently? Thanks!

ADMIN – Hi Heather,

A second collar for the system is $105. It does not need to be set up, it will start working with the system right out of the box.

Jen February 10, 2012 at 10:38 am

Hi, I am thinking on purchasing the 4100 for my black lab. Wanted to know what gauge wire comes with this? Thank you!! Jen

ADMIN – Hi Jen,

The Innotek comes with 20 gauge wire standard. If you want thicker wire we can upgrade it to 18 gauge, 16 gauge, or 14 gauge for you. Just click the “Add to Cart” button and you can configure your system on the next page.

Greg February 7, 2012 at 11:04 am

I have been using the 4100 (based on your recommendation) for 1 1/2 years with great success. We added one of the “Zones” to it as well. I am wanting to add either a remote training collar or bark collar. Is there any way to upgrade what I am currently using so that we don’t have to make the dog wear 2 collars? If not, is wearing 2 collars a problem? I am not wanting to make a whole new investment in an entirely different system. Thanks for your help!

ADMIN – Hi Greg,

You can use an Innotek IUC-5100 collar (and remote) to serve as a dual purpose remote trainer and dog fence collar. There are unfortunately no dual purpose dog fence and dog bark collar systems.

Dogs can wear 2 collars without any problems.

Stacy February 5, 2012 at 10:10 pm

It looks like the IUC-4100 will be the best system for my 2 labs. My problem is I don’t want to enclose a circle of property. I want to run a straight line to keep the dogs away from a fast road. I hear the words boundary wire and twisted wire. Do I need to run boundary wire in an oval shape along the road? How close can the circle be? Thanks, Stacy

ADMIN – Hi Stacy,

Correct. To create a straight line barrier – you want to create a long thin oval shaped loop, with the opposite sides of the loop at least six feet apart.

Sarah February 5, 2012 at 6:31 pm

Thank you for your site, it has been very helpful in our research for an invisible fence for our dog. We are torn between a couple of options due to our situation. 1) We have a 100 lb male doberman (low pain sensitivity). 2) Our property is mainly a wooded lot, with the front yard having some open space (1/4 acre), but has variation and slopes. Through what we have read, we won’t get a wireless fence. Can you provide some guidance as to what system is best for our situation? Can you explain running the wire through something like a waterhose to protect it if we do not bury it in some parts? Thank you!!

ADMIN – Hi Sarah,

1. For a doberman, particularly one with low pain sensitivity, the PetSafe Stubborn is always a good bet. You rarely need the full strength of the system, but it is good to have it in reserve in case you need it.

2. In wooded areas, you can just staple the wire down and it will usually just bury itself over time. If you want some extra protection, you can use a thicker gauge of wire or run the wire through some type of protective conduit. Sprinkler system irrigation pipe and hose pipe works well. You get a long length of the pipe, straighten it out and then start feeding the dog fence wire through. Using fish tape, and pulling the dog fence wire through also works lets you get longer runs if you have fish tape handy.

Joe Lewis January 29, 2012 at 2:16 pm

I’m thinking about buying a Innotek IUC-4100 and install it myself. Can I run the wire through an area that’s under 2 – 3 inches of water a majority of the spring and well into the summer? My current plan calls for running the wire about 50 feet through this area. Will this work?

ADMIN – Hi Joe,

Yes, you can run the wire through standing water. It helps if you run the wire through a protective sheath like an old hose pipe or sprinkler system piping, but this is not mandatory. It is also useful if you staple down or weigh down the wire so it does not move around. Also, try and arrange the wire so that you don’t have any splice points underwater.

Kelly January 25, 2012 at 9:39 am

I have a 17 month old Australian shepherd, who has figured out he can jump over my 4 foot fence, I have 2 other dogs that do not have any interest in jumping the fence. I was thinking of getting the Innotek IUC 4100, and not putting it in the ground but attaching to my fence to use a an additional deterrent to prevent him from jumping the fence. Would this be the right product and is it okay to attach the wire to our fence? Thanks, Kelly

ADMIN – Hi Kelly,

You can indeed attach the wire to the fence. If you have a fence available, using zip-ties or staples to hold the wire on the fence is preferable to burying and is much easier. If you use a weed eater, just make sure you run the wire at least a foot above ground so the wire does not get hit when you are doing yard work. Once you have run the wire, you will want to adjust the boundary width dial so the correction starts a couple of feet before the fence – you don’t want it starting only when the dog is sailing over the fence because at that stage it is too late for the dog to change his mind.

The Innotek would be a good choice with an Australian Shepherd. We find Aussies are easy dogs to train on a fence system because they are smart, eager to please and sensitive to the correction.

HiCountry Rick January 23, 2012 at 7:44 pm

This will be my first invisible fence. I have 130 lb. year old German Shepherd who I would classify as a stubborn dog. I have 20 acres but will only be enclosing about 5 of it for the dog. I’m down to-the Stubborn Dog model by PetSafe or the SportDog fence. They sound almost identical. Or possibly the Innotek IUC 4100. Thank You, Rick

ADMIN – Hi Rick,

With a German Shepherd that is a little more hard headed, I would use either the SportDog or the PetSafe Stubborn. You are right in thinking they are almost identical. Both will serve you well. The transmitter on the SportDog is a little better, and the collar on the PetSafe is a little more powerful. Given you description of the dog and that you are only doing 5 acres, I would go with the PetSafe. The PetSafe is also a little cheaper.

The Innotek IUC-4100 is good, but not quite as strong. It will probably do the job, but I would rather see you have a collar that has a lot of power in reserve, in case you need it.

Chad Pigg January 22, 2012 at 11:10 pm

Great website – I have a few questions, I’ll try to be brief.

1. I’ve talked to a professional installer that installs Dog Guard equipment that he says is manufactured in New York state. He claims the unit is much better and the electronic components are stronger. He also says that the Pet Safe / Innotek units have a high rate of failure. His price for about 1/3 of an acre is about $1,000. I’m a fairly capable person with handy man tasks, but I don’t want to waste $300 on a unit only to have to replace in a year.

Is this “American Made” unit really better / stronger?

2. I have two lab / shepherd mixes. They are female, about a year old and approximately 50 lbs. They are in a 4 ft high chain link fence and have learned they can climb the fence and escape. I’d like to run my wire along the top rail of the fence. My goal is to maximize their yard area and just keep them off the fence.

Is there any problem with stringing the wire along the top of the fence?

3. Several people have told us that our dogs seemed particularly aggressive/destructive –

Should we go ahead and try the IUC-4100? It sounds like a great unit, or go with the stubborn dog unit?

4. One of their regular tricks is ripping each other’s collars off.

Does any manufacturers warranty cover this?
I read that the bitter apple spray works well – I’m ready to try arsenic (not really) – Is this your best recommendation?

I’d much rather buy from someone that I can call with questions if I get in trouble as opposed to one of the big boxes. Any assistance would be greatly appreciated. Thank you –

ADMIN – Hi Chad,

1. We are not as familiar with Dog Guard as we are with other full-service brands like Invisible Fence, they are smaller and we don’t see them much in our neck of the woods. So, we can’t say anything intelligent about Dog Guard specifically. But, generally we are pretty skeptical of these claims of being bigger/better/stronger. I am sure the Dog Guard is a good system. Lots of the DIY systems are good too and will last for a long time. The newer Innoteks (4100/5100), newer PetSafes (Little Dog, Stubborn, Deluxe), the Perimeter and the SportDog (SDF-100A) all should last you the life of the dog. In particular the transmitters don’t tend to go, with no moving parts, we rarely see them break. If you do get a breakdown after the warranty, those brands all will repair the unit at a fixed cost, so it should cost you closer to $50.

2. Running the wire along the top of the fence is fine.

3. It is more to do with pain threshold than aggression. If you observe your dogs being indifferent to things that should hurt (they run into a wall, or someone accidentally stands on their tail, and they have no reaction), then the stronger Stubborn Dog unit is the way to go. Otherwise, the Innotek will be fine. When there is a fence already in place, you usually don’t need as much correction – because escaping takes much longer they cannot run through as easily.

4. We get good results with the bitter apple. Anything with an unpleasant spray works. The manufacturer’s warranty does not cover that kind of damage. Anecdotally, we have heard customers getting a replacement under warranty anyway – but I would not rely on it.

Shelia January 21, 2012 at 6:21 pm

Very Informative website but I am still uncertain as to what would be the best inground system for my dogs. I have two beagle/mini pincher mixes that are 4 months old. I have one and half acres that I want to fence them in and would be running the wire along an old barbed wire fence on two sides and burying the rest. I am concerned about battery life on some models and if a rechargeable would be better. Also I am wondering if the collars can be left on the dogs all the time if it doesn’t seem to cause any problem to their necks. They sleep in our garage and have a door to come and go thru so they can go out to use the bathroom at night and I don’t want them running off. Also I am wondering if they run thru the fence, can they get back through without being shocked. I am afraid they might not be able to get back through to get home. Your recommendations on which system might be right for us would be greatly appreciated.

ADMIN – Hi Sheila,

Happy to make a recommendation. What is the weight of the two dogs, and what is their temperament like. (FYI – if you wait till six months, training will be a lot easier)

If you are checking the neck at daily for the first two weeks, then weekly and aren’t noticing any problems, then you can leave the collars on all the time.

If the dog runs through the fence, they cannot return without getting the correction. Of course, with a properly trained dog this should never happen, indeed the dog should not realize that running through the fence is an option and will assume the correction zone extends out indefinitely.

Jaimee January 19, 2012 at 9:09 am

I am wondering if this system is compatible with the collars from the UltraSmart training sytem. I can’t find the model number on mine – got it about 6 years ago. It is the heavy duty one that has over a 1/2 mile range. I know it was compatible with my other set with a much shorter range. I didn’t know if they would work with the fencing as well since they were not technically called the contain and train back then and it was sold separately as just a training tool. I used it while out riding with my horses so that my dogs would stay close by if a deer or other animal peeked their interest in a chase!

This site has been so helpful – I’ve learned so much! This product will definitely meet my needs after reading all of your answers to others!

ADMIN – Hi Jaimee,

Unfortunately none of the dedicated training collars from Innotek (or any other brand) work with the dog fence. You need to use one of the dog fence collars.
