How many times have you heard of a Collie mauling someone? Or even a German Shepard? Of if you want to get deeper into it... a Chow or Doberman Pincher? Come to think of it, by far the majority of mauling/killings by dog are from Pit Bulls. Those of you that defend these dogs are just the lucky ones. Your pits have not YET attacked someone. Its like smoking... not everyone that smokes will get lung cancer, but most with lung cancer have smoked.
