I once had a T shirt with pictures on it of American Pit Bull Terriers and American Pit Bull Terrier puppies.
The caption was "All dogs were puppies once".
I wore it too often and it is now gone.
The thing is, all dogs once were puppies and we humans have the opportunity while our dogs are puppies to mould them into the adult dogs we want them to be. Some of us are better at this than others. I don't pretend to be one of the world's best dog trainers but I have managed to make sure that my Hobbes is not a problem around other dogs.
Glen Bui of the American Canine Foundation states unequivocally that he he can train any pit bull terrier to be good around other dogs. I am not up there breathing the same air as Glen does, but he is successfully training American Pit Bull Terriers to be non dog aggressive.
So, all you people who state that American Pit Bull Terriers are damned by their genetics to be dog aggressive have yet another expert who says you are wrong. As others on this thread have said, genetic predisposition is not an absolute. It is a tendency but can be trained out. You just have to put the effort in.
American Pit Bull Terriers are just another dog breed, and they require love and good training like any other dog breed. If a dog trainer says that they cant help you with your APBT, I'd suggest that they are actually saying that they are not a very good dog trainer. Even the popularly reviled Cesar Milan has no difficulty training American Pit Bull Terriers.
Anyone here in WA, I can recommend two dog trainers who can certainly help you to train your American Pit Bull Terrier; these dogs are fine dogs, but they are just dogs and they respond to good training.
The APBT is the best of the best dogs (but it is just a dog, like any other breed of dog)
