Pet's info: Dog | Maltipoo | Female | spayed | 17 years and 11 months old | 11 lbs
My dog has a very brown tooth and very bad breath. She’s got a few others brown, but there’s one on the left side that’s all brown. Sometimes I see a bit of brown gunk on her lip that I clean with a tissue and the tissue comes out brown. I’m not sure if it’s a bit of blood or just saliva mixed with the color of her kibble. I don’t know if it’s recommendable due to her advanced age and the fact she’s got a bit of kidney disease that she gets a cleaning?
