Why does my senior dog have worsening bad breath with healthy teeth?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed

My black lab is 12 years old and has extremely bad breath. It seems to be getting worse also. Her teeth are fine and when I mentioned it to a vet 2 months ago they didn't seem concerned. Should I be worried?

If Tehya's teeth are fine, I would recommend getting blood work on her to make sure her kidneys are ok. Sometimes with kidney disease they can have a bad smell from their mouth. I would also discuss with your vet about potentially performing a dental procedure with x-rays to confirm there is no abscess we can see.
