Thanks for all the thoughts on anal glands, etc. Bogie is back to his bouncy self this morning, sparkle in his eyes, tail wagging and happy with life.
When I talked to the vet yesterday, she said he could be sore from the anal gland expression (it was done while he was out) and residual effects from the drugs that sent him to lala land while they cleaned his teeth. She said every dog reacts differently, but she was surprised he was acting that way the following day.
I just wanted to let everyone know that he's OK!!
