What makes dog's breath so stinky???

sometimes it is what they eat. It can also be gingivitis in which case they need their teeth cleaned at the Vets. Or it could be a decaying tooth causing the smell as well. Look in the mouth and see if there is a bunch of tartar build up on the teeth. or if you see a tooth that is black or looks nasty.

the thing that makes it stinky is that it likes it but which makes it stink.

CKECK HIS TEETH AND HOPEFULLY THEY'RE IN GOOD SHAPE

Have you tried changing her food?

Try giving your dog Greenies. they help with breath.

I am surprised as I would have guess his teeth.
