Yikes! I hope you are both ok, physically and emotionally. That is so scary. Did you report to animal control? Did you go to the doctor and vet? My worst nightmare.
Where I live, we don't have a big thug population (compared to some other states), but there are thugs. And many do have pits. However, we are a very compassionate state, a very liberal state, and many of these re-habbed dogs and their puppies end up in the hands of some very, very loving and well-meaning people. These people think that it's the people raising them, not the breed. In the whole nature versus nurture puzzle, they seem to believe that nurture always wins. Or maybe it's just rose-colored glasses. But these are very powerful dogs with very powerful genetic instincts and these dogs were bred by taking the toughest male and the toughest female and putting them together to make really tough puppies or it was random -- who knows.
Pits in the wrong hands are the number one reason we do not go to dog parks or off-leash areas with the rare exception and only when there will be minimal numbers of people and dogs, to decrease our chances of running into well-meaning people with dogs that were bred to fight and kill. I cannot tell you how many times I have personally seen a pit puppy born into foster care, loved, then placed at 8 weeks of age into a loving home, go from a friendly, sweet pup, to a young dog that cannot be trusted with other animals. Then, sadly, I never see that owner again. Or, worse, they keep coming, keep thinking it was a one-time thing. Or that the dog was "just playing."
While I'm not sure that the breed should be banned because I'm not sure that even works or what it will mean going forward for dog owners, I do think there should be some type of regulation that is enforced. Often, when we make things illegal it just creates a dangerous black market. I could see pits getting banned so then the worst of the worst is breeding them in basements, and selling them on some kind of a black market. Not that it's not happening now, but at least there is SOME transparency.
I don't know what the answer is, either...
