Rating : - Not for Medium Sized outgoing dogs
This product worked really well for about 1 month. We have two 7 month German Shepard/ Chow mix one of the dogs chased a cat and ran straight though the invisible fence. Bad news for the Cat..... We now have the Stubborn dog collar on him now. We will see how that will work for him now.

But if you have a low energy dog. It works Great... His brother never goes by the invisible fence. He does really well with this collar.

It depends on the dog.
