deafhound, please keep an eye on your dog--who knows when or if your AH will decide to make good on his threat of killing her? It would be so awful if anything happened to your hound friend. And please don't underestimate your A and what he might be capable of if he truly feels threatened (and he may indeed feel threatened by the changes he sees in you). Hurting you thru your dog might make sense to him when he's drunk....
Take care of yourself and that little terrier friend!
