Fletcher had a little tarter build up, but my vet said his teeth were fine. A couple of months ago, I started noticing doggy breath, but blamed it on the fosters . When I finally realized it was him, I took him in and he had a abscess He had to have his first dental in 6 yrs and lost the bad tooth. It wouldn't hurt to have the vet check her teeth if you can still smell doggy breath.
