My dog has killed SO MANY of my chickens, and I am at my wits end. I have heard of training methods using an e-collar, which I have and he is trained on in other areas of his life, and I am wondering, has anyone used an e-collar to teach their dog not to kill chickens? In more depth, the method is this: put a chicken in the yard, and then release the dog while you hide and watch. Once the dog tries to go after the chicken, you shock him on a very high level with the e-collar. Basically he will associate chasing chickens with pain, and he wont do it anymore. Does this work? Is it "abusive" to do this to your dog? My thinking is that a moment of pain for my dog is worth it if it means the life of all my birds.
