Sorry for the off-topic, but some dog lover you are! With pit bulls the problem is the owner, not the dog - just like with any other breed. In fact, pit bulls were bred to be people-friendly (those who staged dog fights didn't want the dog to transfer aggression when it was time to break up the fight). The problem is that nasty people who want to train a dog to be mean will pick a pit bull cause of its reputation of such a tough and deadly dog.

I volunteer at the Toronto Humane Society by walking dogs there (I ride my bike there of course ). I get a lot of exposure to all breeds of dogs, and pit bulls have become my favourite! They are usually the most affectionate and the smartest dogs there, despite the fact that many of them had it pretty rough in life.
