Q. My 7 yr. old female dog has started to have breath that smells like maple syrup. I had a full blood panel and urinalysis and everything was fine.

A. This can be an indication of a problem in breaking down amino acids. The odor would be from the urine usually though. (urine analysis test will not show this).
there is a test to detect this condition in human medicine but i'm not sure it exist in veterinary medicine as this condition has never been officially diagnosed.
Some people find a yeast infection of the ears or skin smells like this.
