I love my pitbull mix. He is mixed with american bulldog. He is very sweet and very loving. He has had one incident were he was gotten aggressive but it has since been figured out why he got like that and worked out. They can be very good dogs or they can be very bad dogs. It all has to do with how they were raised and socialized. You can make any dog mean. Even labs and Goldens can be mean if raised to be.
Secret to a successful life is not in playing a good hand, but in playing a poorly delt hand well.
