Could she have compacted Anal glands? They sit at the base of the tail on either side.....sometimes you have to squeeze them? I'm surprised the vet didn't try that one. Usually they get released when the doggy does poo....and it lets of a god awful smell....
Yeah I had thought it may be that too, my old foxxy had that problem a couple of times. She checked around that area and didn't find anything, but maybe she didn't check right? We'll be keeping a close eye on him, making sure he poops. Thanks
