My dog has foul breath, but her teeth are healthy. What's wrong?
It's odd that it improved when the [Giardia](https://www.petcoach.co/dog/condition/giardia/) was treated. My first suspicion for the ongoing odor is that she may be licking at her anal glands or eating her own (or someone else's) poop. Ideally, have her examined by a veterinarian just to make sure there are no wounds, irritation, etc in her mouth or throat that maybe contributing. You r vet can also check her anal glands to see if they seem full or irritated which could lead t her having a tendency to lick at them a lot. If her anal glands are fine, and her mouth is fine, use a daily product for dental health. [CET products](https://us.virbac.com/cet-veggiedent-fr3sh-dental-chew-for-dogs) contain chlorhexadine which kills bad breath causing bacteria.
[Water additives](https://www.petco.com/shop/en/petcostore/product/zymox-oratene-water-additive) are great too.
I hope thats helpful for you. Thanks for asking PetCoach! Good luck!
