I don't trust any animal with teeth bigger than mine.
But on a serious note - I don't like pit bulls; I don't trust pit bulls; I don't want them any where near me. I had neighbors with them - I rejoiced when they moved. They didn't abuse their dogs - but they were unregistered, unlicensed, and called themselves 'breeders'. In a residential neighborhood full of small children and they had no FENCE. Glad they're gone and glad the dogs are gone, too.
People on a paper route in Florida had a pitbull...they needed a logging chain to keep it restrained. Have you ever seen the size of a logging chain?
Sorry, Chatty. We will have to disagree on this one. I see no useful purpose for this breed in this day and age. I feel sorry for them (the dogs) but they were bred to be what they are.
