Misha had a spa day today, while he was there the groom sent me a text.  She thinks he has broken his tail.   There is a "bubble" about 5 bones up from the base of his tail on the under side.  He does not seem to be bothered by it, does not show signs of it hurting when she groomed him.

I guess I call the vet in the morning and see if there is anything he needs to do....  

Any one been there on this one?
