Sorry you are going though this. As others have said, bitch fights are the worse and they can carry a grudge. We did have to re-home a beautiful champion, because she just hated other dogs and no matter what we did, it didn't change a thing with her. We figured it wasn't far to her to keep her away from everyone and she didn't get the loving she deserved, so we found her a loving home in Florida. Broke our heart, but it was the right thing to do for her.
