Have you ever seen a puppy of a working dog? Pointers will point. The training they receive is what to point, not how. Retrievers will retrieve, herders will herd, trackers will track. But when someone suggests that a dog that has been specifically bred to fight and kill, oh, they were just trained that way. No, they have been specifically selected for aggression and prey drive. It is at best naive and at worst deadly to think that a working dog comes as a blank slate and will only perform actions it has been trained on.
