My dog's one nostril is bleeding with mucus for 3 weeks. What's wrong?

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.

The two main options are a foreign body in the nasal cavity or a nasal tumor. in order to find out what it is he will need to be taken to the vet and either an endoscopy or a CT scan will need to be done to get a diagnosis.

Poor Daisy! She is an older girl, and unfortunately this sneezing with blood in her snot could be due to a malignant growth (cancer) in her nasal cavity. It could also be due to a foreign body, fungal infection, or respiratory infection. Because this has been ongoing for a while, it's best that Daisy is seen by a vet either today or tomorrow. The vet can do a physical exam, blood tests, urinalysis, x-rays, and may look up her nasal cavity with an endoscope to diagnose what is causing her symptoms. Once a cause is found, the vet can discuss treatment options with you.

Poor Tersk! Nasal discharge with blood is always very concerning in dogs, and is not likely to be due to a simple cold. I would be concerned about a possible nasal tumor, a fungal infection, or even a foreign body such as a foxtail or a blade of grass stuck in the nasal cavity. These problems generally do not show up on x-rays or blood work, so I agree with your veterinarian - rhinoscopy would be the next step to try and get a diagnosis.

It's true that fungal infections can be a cause of nosebleeds in dogs, but they can also be caused by nasal tumors or even a foreign body such as a blade of grass or other plant material. Since there has been no improvement in four months with antifungals, I would be concerned that something else may be causing the bleeding. I would suggest having a rhinoscopy done to visualize the inside of the nasal cavity and take biopsies and culture samples of the tissue there to determine if the bleeding is really caused by a fungal infection or some other problem.

I am sorry that she is having this problem and I am sure you are worried. Nasal discharge with blood can be a sign of infection, cancer, or possibly a bleeding disorder. If the antibiotics do no resolve the problem then your vet will need to do some diagnostic tests to help determine the cause. Your vet can run blood-work, take nasal x-rays, and/or rhinoscopy to see if a diagnosis can be found. I wish I could tell you the cause but am not able to without more information from tests. The bump on the roof of her mouth may not be related but you should monitor it and have your vet take a look at it. Try not to worry as it could definitely just be an infection.

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.
