    Is your dog's bad breath a sign of sickness?
    Will Draper, DVM posted:
    "Dog breath" is never particularly appealing. However, it is important to distinguish it from halitosis, or "bad breath". Usually with dog halitosis, our first thought is that it's the result of nasty teeth. With the buildup of tartar and dental calculus, followed by gingivitis and tooth infections (periodontitis), there may be odor-producing bacteria in a dog's mouth that can cause unpleasant breath. However, other things can cause bad breath in dogs. Oral foreign bodies -- such as a stick caught in the roof of a dog's mouth -- will cause inflammation, infection or abscesses, and then subsequent odor. Oral tumors can also cause bad breath. In cases where you feel like your dog's breath is worse than usual, all of these possible causes are reasons that make thorough oral exams very important.

    Sometimes oral odor can be an indication of internal problems, such as esophageal or gastrointestinal illness. Gastrointestinal injury, foreign bodies, or masses can all cause inflammation, which will eventually lead to odors. Certain things your dog will ingest (like cat poop from the litter box...) can cause bad breath. And even "regular" dog food that may not agree with your dog's system can cause an increase in gas production, which will cause odors to escape from either the top or the bottom.

    Though more commonly noted in cats, kidney disease could also cause bad breath in dogs, due to the buildup of toxins (uremia) in the blood stream. After your vet collects a full history and performs a physical exam, the buildup of toxins is generally determined by running blood chemistries to measure a pet's blood urea nitrogen (BUN) levels, as well as other values such as creatinine and phosphorus levels.

    Has your dog had issues with bad breath?

    My dog, 10, has a bad dental situation, but because he also has abnormally high liver enzyme values (high and continually rising, alas), my vet cannot do a cleaning under general anesthesia for fear of further liver damage. Freddie also has an enlarged heart. So his breath is a bit rank but actually not horrendous.

    I have a mix which has the most horrendous breath ever! I know I need to get his teeth professionally cleaned cause brushing his teeth (which isn't a fun job) doesn't seem to last very long. I try to make sure he has plenty of chew toys which are supposed to be for dental health but nothing really helps. Because I have two other dogs with health issues, his diet is carefully monitored so I can't imagine he would have any other issues. I just wish the professional cleaning wasn't sooooo expensive!

    I have this problem with my 2 year old yorkie. She has a dental done every 8 months and it helps but does not make it go away .I brush her teeth a few times a week and use nolvadent daily which has her breath smelling minty for a while but I hate this smell she has. My vet says Yorkies have a tendency to have an odor to their breath. Has anyone heard of this in yorkies?
