breeds aren't the problem, its the aggresive owners who are at fault. i know a lady who breeds pit bulls, about 10 of them, and they're the best dogs i've ever known. the only dog i've ever been bitten by was a dachsund, and my god it hurt. went through my jens and right into my calf. but you can't stay mad at something so small, even when it charging towards you in a foot and a half worth of rage.
