We have a pitbull in our neighborhood. He is owned by a policeman who lets him out every morning to wander the neighborhood. The pit came into my yard while I was playing with my dog. He growled at me then ran away. The biggest problem is the two half labs down the street. They attacked my dog while I walked her on a leash and they snuck up behind my neighbor while she was trying to teach her daughter to ride a bicycle and bit her. Left a black bruise the size of two out stretched hands. It just depends on how much control you have on the dog and how it was raised. Neither of these senarios are good.
