  Just another possibility - When my Shi Tzu was a puppy, he had HORRIBLE breath.  When being neutered I asked the vet to take a look.  He found, waaaay in the back, a piece of carpeting or stuffed animal or something that had gotten caught on a back tooth and had rotted.  EEEWWWWW.  It wasn't visible until he was asleep and the vet could really take a good look back there.  He said that they chew so much on everything, that can happen.  And if you can't see it, ...... well, you can only smell it!!  |
