How does your dog handle vet visits? Is s/he calm and friendly or does s/he freak out? Ours doesn't really go that often and is on the older side now, so he's not exactly thrilled with the idea of being taken to see strangers. He hasn't bitten one, but they did muzzle him the last time, just in case, because they were going to mess with his feet and he has pain there, so it was on the cautionary side.
