This can be due to a build up of tartar around Moe's teeth, or it could be due to another dental problem such as a tooth root abscess or broken tooth. I would have Moe seen by a vet first thing on Monday to have his mouth examined. If he does have a dental problem causing his bad breath, then he will likely benefit from a dental cleaning, scaling, polishing.
