Dog Containment Fence Training a Older Dog, a Pup, and a Pacemaker

A reader asks about training on the dog containment fence system, when you have an older dog ready to train now and a younger dog that is not quite old enough, but will be trained later.

We adopted a 3-4 yr old lab mix and a 4 month old mountain feist / setter mix. Our older dog likes to run off and is difficult to get back home until he decides he’s ready. I would like to get an electronic fence to be able to let the dogs run without being tied up. Our lab mix is 30-35 lbs. and the pup’s parents are about the same size (30-35 lbs.) so we believe he will be too. I thought we could install the dog containment fence and train the older dog then train the younger dog in a couple months. I am thinking about an Innotek IUC 4100. Does this sound like it would work? How much training is involved? Also will the fence cause interference with a heart pacemaker.


Hi Cheri,

That sounds like a good plan. Often when you train the older or more dominant dog, you get the younger dog trained almost for free. The younger pups will tend to observe the same territorial boundaries as the older dogs, just because they follow them around all daya nd they notice the older dogs never stray beyond the boundaries, so naturally they will also start to observe that boundary as well. Of course as they get older, and reach adolescence without training and their own collar they may start to wander (especially young male dogs). But, generally teaching the young dog tends to be much easier because they already know the deal.

The dog fence training is two weeks, doing two or three ten minute sessions a day. You will do a series of exercises to teach the dog that when they hear the beep they need to turn and retreat. Then you will spend a couple of days testing to make sure the rules are being obeyed even when there are big temptations on the other side of the fence. Then you will start letting them out for longer and less supervised free play outside.

On the issue of the pacemaker, I would not expect interference, because all the system is doing is sending out a radio signal, just like an AM radio station. But, I would definitely consult with a physician, that is well out of our area of expertise!

Hope that helps

    Our Tibetan Terrier has a pacemaker and on occasion has seizures. We will ask our vet, but from your perspective, would an invisible fence cause issues with him? Thank you.

    ADMIN – Hi Shaunalee. This is truly a question that is best answered by your veterinarian. You can let them know that the correction is a static correction and not an electric shock.

    Can you train a deaf dog to obey the boundaries of an invisible fence? I have a very sweet but timid 4 year old female boston terrier who is deaf. She walks on a leash and will in fact not go outside the door without her leash.

    ADMIN – Hi Wanda,

    You can train a deaf dog, but instead of using a collar that beeps to warn the dog, you want to use a collar that vibrates as well so the dog gets some warning of where the boundary is. Vibrating collars, will shake (just like a cell phone set to vibrate). Vibrating collars include the PetSafe Stubborn, the Dogtra EF-3000. They are both bigger collars than is ideal, but should be fine on a Boston.
