I would definitely bring him in for a check up. I had my yorkie in for wetting problems and never had the best of luck with my vet. I finally found someone and she was diagnosed with incontinence which is easy to treat. Also she had calcium oxalate crystals. We never disaplined our baby because we knew she was trained and could not help her wetting problems. We were told by one vet she had a behavorial problem but anyways now she is doing great and no more problems. Susan |
