My dog is almost fifteen and has a green discharge from her nose. What would cause this?


A green discharge from the nose is most likely an infection, so with a 15 yr old dog I would assume it was an infection in the teeth. I would want to check her for cancer though, and there is always the possibility that it is just an infection in the nasal cavity.
