That's a great story. Pitbulls are a great dog. I go to the SPCA and pet the dogs. By far, the majority are pitts. Some are the most lovable, sweet dogs even with all the chaos all around them. I Don't agree with banning a breed, but I would say it's because of the potential of the Animal. One of the worst breeds out there for behavior and biting is a Chihuahua. It only gets away with it because of its size. If a pit bull acts like that, it's horrifying, and must be a killer. 95% of dogs are born to be followers. There's an Alpha dog and a few that want to be. I agree with Tex, That it's largely environment. Either no leadership, or bad leadership can create a dog that's dangerous, of any breed.
