I've read and seen on video other cases with Pit Bulls being loose and attacking people. Why do they do it?
When I was a kid we had stray mutts running around all the time. One day I spent like 4 hours chasing this Flat Coated retriever mix around the neighborhood and she finally let me catch her. I never once as a kid thought a loose dog might come after me and try to eat me.

SO.
All of this being said then, what would your dog do if it was loose? Based off of the things you know about your pets, how do you think they would react?
I think if LiLo was loose and away from her home I think she would have her tail tucked and be fearful. I think if a person approached her she would get defensive and bark and growl, but if they charged her, I think she would bark but run away. If a person was walking away from her I do not think she would chase them, or even approach them because she doesn't like people she doesn't know and is fearful.
Seth has jumped the fence at my parents and has gotten out once with another person around. The guy was walking his 3 weenie dogs and he grabbed Seth by the collar. Seth's tail was wagging and he was more interested in the guy than in his dogs. I think if Seth was loose he would definitely come to anyone that would give him attention. I think if he saw a person walking by he would probably approach them. I think it is unlikely he would ever attack someone. He loves everyone and would just want attention.
I really just don't think that if my dogs got loose they would try to hurt someone. This is all obviously speculation but I just wondered, what do you think your dog would do if it got loose? Do you think it would try to bite someone? Do you think it would just become another dog bite statistic? Are we breeding Pit Bulls to be human aggressive?
