the other side of this is how many dogs need training to not randomly attack and bit people? I have had several mutts with no training who were just great dogs. Does a pit require training to not attack?
Not at all. My girlfriend has a pit, and she is the sweetest dog ever. I can show you a dachshund who is 150x more likely to bite you. First time I met her, she attackes me... with kisses. Everytime she sees me she wants to lick me. She's like that with everyone. It all depends on how they're raised.
