Why is my dog's nose runny and bloody? When should I worry and act?

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.

Im so sorry Luna isnt feeling well. Given her age and breed, the most likely culprit is allergies or an upper respiratory infection. The nose can be so inflamed from the aforementioned problems, it can start to bleed. Other unlikely causes are a foreign material stuck in the nose, high blood pressure, or (least likely) a mass in the nose. You should have her seem for the appropriate treatment. Hope this helps!

I would be concerned about possible damage to the sinus tissue, a platelet disorder leading to her bleeding easier or even something like a bacterial infection causing a vasculitis which is when the blood vessels get leaky. I would recommend Lucy get checked out by her veterinarian so they can make sure she doesn't have any sort of bleeding issue or infection as if either those are present this could get worse.

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.

It looks like her nose is very dry and cracked. To be safe, I would get her in to see a vet as soon as possible, especially if she's feeling sick otherwise, any unusual lethargy, refusal to eat and drink, vomiting, diarrhea could all point to this being a much more serious condition. I do recommend very gently cleaning her nose and applying a thin protective coating of Vaseline to her nose to help slow the cracking and dryness.

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.

Poor Bailey! Coughing up blood along with bleeding from the nose are quite serious, and I would take her into the vet now. This bleeding could be a sign of ulcers, an inability to clot blood, liver failure, respiratory disease, or cancer. Unfortunately, cancer is always a possibly in an old dog, and if she did have cancer that had spread to her lungs, it could cause these signs. I would take her into a vet right away. The vet can do routine blood tests, a urinalysis, x-rays, and possibly blood clotting tests to see what is causing her to cough up blood and have nose bleeds. Once the cause is found, the vet can determine what, if any, treatment is appropriate for her.
