We have two King Shepherds and Pit Bull. I spend 15 mins a day with each dog, individually, reinforcing their training. I remind them every day, in a firm but loving manner - no yelling, no hitting, and most days no treats - who's in charge. Each day, outside of training - sometimes with birds out and about, I give commands to ensure they respect me. Training is paramount.
Breed specific bigotry is wrong because we need to understand what the owners of the dogs who harmed/killed people were doing and if they participated in training their dog(s).
Oh, and when I was down, my dog didn't bite me. She most certainly loves me. She saved my life six times by recognizing I was having a stroke and she went to get my husband. Years ago, my autistic daughter asked me, "Mom, what is love?" I realized that love can be defined in many ways, and Fenway loves me...
As far as Pit Bulls, our Angel is so grateful to be in our home. Even after 20 months of having her, there's this look in her eyes as she seems to digress to the time when she was emaciated, scrounging for food and not finding nearly enough, covered in sores, nearly hairless, and by her behaviors we recognized she had been beaten. She has a a warm place to live, premium food, excellent treats, femur bones to chew, vitamins, and she can sleep on a nice comfy bed with people who love her.
Just because it might be a pack mentality doesn't make it any less love.
