Why is my dog's nose bleeding daily for months, despite treatment?

I think you need to get a second opinion from another vet, preferably one who has a rhinoscope and can actually look into your dog's upper respiratory passages. By examining the nasal passages with a rhinoscope one will be able to see whether there is a tumor present or more plant debris or foreign material that may need to be removed and so stop the constant infections and bleeding. Your vet may be able to refer you to a relevant clinic.

Poor Mazie! A fungal infection like aspergillosis is certainly one possible cause of persistent sneezing and nosebleeds that are not resolved with antibiotics. Other possibilities would include a nasal foreign body, or a nasal tumor. I would recommend talking to your veterinarian about the next steps from here to try and get a diagnosis. In many cases, referral to a specialist for rhinoscopy and a CT scan is needed to determine the problem.

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.

Nose bleeding is usually either caused by an infection called "Tick fever", a fungal infection in the nose or a tumor in the nasal cavity. you must take him to the vet in order to get it checked and treated, it is a very serious symptom and there is nothing you can do to help him at home.

Left nasal cavity seems full of discharge and bone seems affected as well (so whatever is inside is causing bone erosion as well). It is not possible to determine what it is specifically from the CT images and a further investigation is unfortunately needed. Was rhinoscopy performed? was a biopsy taken? Otherwise aggressive treatment for fungal infection is required (not only oral treatment but often ''flush'' of the nasal cavity is necessary to have substantial results. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

This is very concerning, and Luna could have injured her nose, may have a foreign body in there, a severe upper respiratory infection, a fungal infection, or a growth causing this bleeding. You need to take her into a vet now to have this diagnosed and treated.

When it is one nostril then it narrows the causes down to a few possibilities. It is very possible that there could be an object up in the nasal cavity causing these signs. The other concern would be a nasal tumor. Nasal tumors can be hard to diagnose without a CT scan. I will usually do an anesthetized nasal flush to see if it helps. If not then I will usually refer to a specialist for a possible CT. Best of luck and I hope he improves soon.
