I have a male and a female. The female is verrrrrrrrry hyper. The male, complete opposite. Very mellow.

My female is 2 years old and already knows a thing or 2 so she is alot easier to deal with, the male is 6 months and still learning alot http://www.pitbull-chat.com/images/smilies/smile.png

All in all, I love them!
