Why do people insist on having dogs who are generally agreed to be dangerous? I know any dog, any time, can attack given the right circumstances, but some dogs are more famous for it than others, and some people will still insist that their rottweiler or pitbull type is a lovely old softie. Well guess what, they all are, until they attack, otherwise you wouldn't have them in the house. Here's yet another horror story and every time I read one I vow I'll never take the kids to the park again.
