I'm not so sure WHAT the vet thinks of Duncan! I do know that they have to take him in the other room and muzzle him because he will bite them if they come near ME! He is such a sweetie pie though. He doesn't mean any harm, he is just misdirected I think or something.....? Once I am out of the equation, he is wonderful and will let them examine him and play with him, etc. I try to sneak a peek at his file when we go (Like Elaine in Seinfeld! )
I know he has a red sticker and it says PROTECTIVE in big letters. But all in all, I think they like him and try to understand him.
