@nomrbddgs:
She may always be nasty, or it may be a newcomer thing. I have always had younger B's coming into my home. I've never introduced an older B into my home or an older dog for that matter. Perhaps some of the others have more experience. I know the domesticated dogs (most of them) would get over it, but I'm not sure about a B.
I agree…I think it is too soon to tell. She is scared, and hurt, I don't think you can get an accurate assessment at this point. I would keep them separated until she is feeling 100% better, and more comfortable, then go slowly. But let your family know that she may have to go to another home, if the dogs can't work it out.
