Why is my old dog's nose bleeding? Is it a tumor or something else?

Updated On September 23rd, 2025

I have a 13 yr old lab mix who has had nasal bleeding for several weeks. My vet did a CBC but did not see anything unusual. I can tell his nose bothers him due to him scratching it and shaking his head. Sometimes it is clear, greenish but lately a lot of bleeding. He is an inside dog and we have pet turf in our patio area. Without spending a couple thousand $ can we expect it to be nasal tumors. Like I said he is 13 yrs old and already has arthritis in his hips.

At 13 years of age, a nasal tumor would be most likely. A tumor typically would cause bleeding out of just one nostril. Other possibilities would be a severe bacterial infection, tooth root abscess, nasal foreign material (I've seen dogs that had toy stuffing in the nose), or fungal infection. Unfortunately anesthesia for nasal scoping and often CT scan is usually necessary to get a diagnosis.
