a little bit of knowledge is a dangerous thing. I have two mix pit bulls. and have been around several. they are friendly fun dogs. Yes they are loyal and protective. However they are great around kids. They were given a bad name due to idiots training them to fight, bad owners is the challenge not the dogs. I don't care what type you talk about there will always be some bad examples.
Maybe we should muzzle people, and get rid of them? look at all the violence they create.
