We used such a collar to train our dog to stop chasing bikers and it worked. We don't even have to put the collar on him now. Kind of a ridiculous law - people that abuse animals will find some way, and those that don't abuse animals would always zap themselves 5 times with that collar first (as I did) before putting it on the dog. Our dog mostly stays in the house. And when he is out, he stays near, but he would not be too happy tied up I don't think. Because of this training collar, our dog is far better off.
