CaC, they seem to recently come from one though....
//The American Bully is in the Pitbull family, bred from the American Bulldog, English Bulldog and the Old English Bulldog. The American Bully is one of four dogs that come under the Pitbull-type dog umbrella. He is a natural extension of the Pitbull, which is why they are both very similar//
Although obviously put in the wrong environment. This is obviously a tragedy, other dogs have saved their families in fires etc.
