What they did to her would be difficult to untrain I would think. If they turn on you after lovenly raising them from pups, well what can you say. There is not a trainer in the country that would finacially gaurentee this breed would committ no violence, even under the best of circumstances. She trusted them and they ate her.
I have no idea. I just never see one of these stories where anyone comes out says the animal is trained, or not. Supposedly only 5% of dog owners bother to train their animal, I would guess that is way less for pit bulls.
