This was on my local new last night and this morning. Seems as if the woman tried to break up a dog fight between 2 males and one of the dogs turned on her. It doesn't say in this story but they interviewed the womans son and they are going to euthanize the dog. Apparently the dog turned so violent that he wouldn't let go of his owner. Seeing as how this is a champion show dog and has created lots of offspring I hope they don't turn out like the father did.
