Pit bull....

I love all the dog breeds. That being said I've seen a few good dogs temporarily get aggressive. One was a golden retriever. He was the best dog I ever owned. But he nipped at a kid one day for absolutely no reason. I've seen labs do it also. Ankle biters are notorious for it. The thing is, when a pit is having a bad day and it decides to nip the damage is devastating. Sometimes they see red and go full on attack mode. All living beings have mood swings and can surprise you.

I had a horse that would be nice as pie one minute and ten minutes later try to bite you or use you as a
football and try to put you through the uprights from fifty yards. They are animals sometimes they do stuff only that animal can understand.

Pit bulls just do more damage when they act out. Chows are the number one biters, they just don't seem to maim and kill when they bite.
I can't have a pit bull here, we have way to much traffic here.

Friends bring their pits over and they play with my two boxers. Its pretty intense the first five minutes with the high energy both breeds are full of, and my males protectiveness of his much smaller sister. They have never done much more than wrestle though. They start to get a little too aggressive I yell at them and they settle down. My boxers play rough and the pit bulls can take it. They never use any more force than my dogs do. I worry though because its my two dogs against one and if I was the one dog I would get pissed being double teamed like that. I like pits I just can't own one.
