Aggression training inflicts pain on the dog where the dog must quickly learn that in order to suppress the pain he must bite the target. The reason this method is not used at Fine Line Family K9 with our family protection dogs is because whenever the dog feels any sort of pain throughout his life he will bite whatever caused him the pain just like he was trained to do as a younger dog. With that being said, if a kid trips on the dog, or you get out of bed and step on the dog, the dog would then bite you.
