To assume that a breed is vicious just because it looks mean to you ie racial profiling for dogs. I have an 80 pd. pitbull living in my house with a jack russell terrier and my two boys. He is one of my boy's and if an iggnorant person like...You were to kill or try to hurt him, I would hurt you. Pits are very playful, when they ran up on you they were most likely trying to play. Pits think they are small dogs they don't realize they are big or that some people they they look mean.You have experience with your neighbor's dogs and that's all. You are no where near an authority on pit bulls. My dog Mack sleeps in the bed with me and my husband. I would not trade Mack for ALL of your so-called lap dogs.He is the sweetest dog in the world!!! Just because you don't understand them is not a reason to kill them.
