I don't even have a pitbull, or know someone well who does. but I agree. A dog is only mean if the owners raise it to be mean. A Cocker Spaniel could maul a person's face just as much as a Pitbull can. It all has to do with how you treat it and raise it.
I will carry you in my heart and mind all the days of my life until one day, I too will cross over to Rainbow Bridge and gleefully join you there, our youth and vigor restored, never ever to part for all eternity~
