here ... I'd like to suggest that Don and Jackie put a claim for their vet bill against the neighbor's (pitbull owner) homeowner's insurance policy, if they have one. A friend's dalmation was attacked by her neighbor's shepherd/lab mix and needed surgery to repair the torn muscle & skin. The neighbor's homeowner policy reimbursed my friend for the vet bill. I urge you to check into this, it's the least they can do.
