I have an invisible underground fence to keep my German Sheperd on my property. It uses a shock collar. He gets along well with most dogs that come onto my property. He never leaves even when tempted by others. I had a couple chickens killed by a neighbors dog. I always got along with my neighbor. I offered to put my spare collar on the dog to keep him out of my yard but they said it was "inhumane" to shock the dog! My gun is loaded with a very inhumane deer slug & waiting beside the door now. Am I wrong?
