Their are stories of many breeds acting in a heroic manner, they never get published, because those breeds already have a good reputation, unlike Pitbulls who need to counter the regular maiming, mauling and killing that Pitbulls do. A lot of these stories are put out by Pitbull Nutters, they are deliberate PR attempts at reducing the reputation for ripping children's faces off, they are often embellished and sometimes completely fabricated. I have heard them all before, the way the Nutters carry on, you would think Pitbulls won World war 2.
If you want a look into the mindset of a Pitbull Nutter, look no further than the case of Darla Napora, she was a member of Bad Rap, was killed by her own Pitbull and then the husband and the group BAD RAP (A Pitbull advocacy group) hired a PR company to put out misinformation out there that Darla fell off a ladder and died and the dog was licking her and nudging her after the fact to try and wake her. Of course, the Police, Animal Control and everyone else knew otherwise, Darla had horrendous Puncture Wounds, severed arteries and their was no doubt that she did a brutal and violent death at the jaws of her beloved Pitbull. The Coroner marked down the cause of death as a result of Dog Attack, causing severe puncture wounds and a loss of blood. But, to this day, due to the misinformation campaign led by the Nutters and their PR company, you ill hear them claim that it wasn't the Pitbull that killed her, it was actually trying to help her even though the Police noted that the scene looked like that of the worst homicides they had ever seen. Their isn't anything that surprise me about Pitbull Nutters.
