Just as likely... could be bitch nearby who is in heat. Do you have close neighbors with bitches?

I have found a great tool to help with nail cutting/drummeling. It's called the Calming Cap from the makers of the Thundershirt. It goes over the head like a hood and because the dog can't see well, it stays calm. About 20 or so years ago, I used to put a sock over my dogs head. It worked much in the same way. You might want to try it because it really works.
