Doc your right about your dog, Myself and TMBill called around very late the night before we were going to the airport and "Buster" had us bailed up growling and barking, not even TMBill with his one liners was going to distract him from his duties. I have a dog myself and you know when someone is hanging around that shouldnt be, even though she would never bite or hurt anyone she does give warning barks that someone is there and that is enough for me to take a look or for my neighbours to take a glance over.
