To that, I say this:
According to the American Canine Temperament Testing Association, 82.5%of the American Pit Bull Terriers that took the temperament test passed, compared to a 77% passing rate for all breeds on average. In the test a dog is placed in a series of confrontational situations. The first sign of aggression or panic is a failure of the test. Pit Bulls have achieved the fourth highest passing rate of all 122 breeds tested.
I've been around a lot of dogs in my life and have never seen or heard of a pit attacking anybody I know.
