treatments nothing helps he has had cancer test that were negative. Now the sore
has eaten away the whole top
lip and moving into his nose making it hard to breathe. any suggestions?
Has your vet checked for fungas, and/or biopsied the "sore". A biopsy may help determine the cause so it can better treated. vetcare
