First of all, take your dog to the vet man - Don't you know dogs cry in fear not pain?
Second, I would make some calls to the local authorities...if the dog gets out enough, the dog will be taken care of. Obviously, this guy has not trained his dog correctly...I've never met a pit that was mean/crazy unless it was trained to be (ie: fighting). If all else fails like mentioned before, some prestone flavored doggie biscuits will do the trick, I hate to recommend it but i've seen it done before.
