It's not just pit bulls, same goes for any dogs. I had the pleasure over Easter of playing with my brother's jack russel, shitzu, and nephew's bichon frise.

The jack is 12 years old and her name is Jackie (I know how original). The bichon is a fresh 2 year old male named Murphy. Murph decided he was in love with Jackie and followed her around all day trying to get a sniff. I was playing with Jackie with a toy and Murph decided it was his opportunity to get a nose full. Jackie let go of the toy and proceeded to tear after him with a vengeance! He was fine though - I think it scared him more than anything.

The point is they are dogs - and dogs will be dogs. Teeth, barking, growling are they tools they have. It's not about "if" it will happen, it's "when". All dogs have a circumstance that may cause them to use their tools. "He's never done that before" just means that circumstance has not yet occurred.
