My 9 year old male boxer has a tumor in his nostril, at first it was small, now it’s almost blocking the nostril and will bleed when he gets to rubbing it. He does have a bad odor now. This started a month maybe a month and a half ago, came on fast, he goes to the vet this Friday. Just got a good bill of health in May. Has anyone dealt with this before? He acts normal besides licking his nose often and he’s eating well.
