An invisible fence will work for a dog that is fearful and reacts by getting away from pain. A dog that is fixated on prey (people, other animals, squirrels, bicycles, etc) can run fast right over the "fence" and once over it cannot get back. There is the added problem that the "fence does nothing to protect your dog or protect your liability should a person walk on the property and get bitten or hurt the dog.

An invisible fence did not work for two dogs in our neighborhood. They kept getting out and then could not go back home. We got really tired of rounding them up.

It is really scary to be chased by a barking lunging dog and to only hope that the "invisible" fence works. Another person on a forum said their dog was so traumatized by the shock collar that they became incontinent.

I would suggest you try the collar on a local 7 year old first or maybe your husband or wife before you go putting the shock collar on the dog. The collars have been know to fail in the on position and no one wants to do that to their dog.
