The real villain here is the idiot who owned this creature and obviously failed to properly train it, or the other idiot who bred it from poor stock.
Happy landings, stupid mutt. I have to wonder about bringing a baby into a place where a pit bull is loose. That does not make sense. Most dogs will protect babies in their own households, but I would never trust pit bull with a strange child. I agree that guns are far safer than an attack dog.
