If your dog is having trouble breathing, you should be able to hear wheezing. Your dog may also be panting more, as well as breathing more rapidly. [1] X Research source

You should apply pressure until the bleeding stops. If it hasn’t stopped after about 20 minutes, consider taking your dog to the vet.

Continue calming your dog even once the blood as stopped flowing, as moving around too much could cause the clot to blow, creating a new nosebleed.

Expect tests. Because a nosebleed can indicate a wide variety of conditions, your doctor will need to do a full examination, plus a range of tests. The tests will likely include taking both a blood sample and a urine sample for analysis. Your vet may also order x-rays or a CAT scan to help to determine what is wrong.

Your dog may also have a problem with blood clotting. Some more serious possibilities include the chance of a tumor or cancer, problems from eating rat poison, and diseases passed from ticks.

Medications can also cause nosebleeds, particularly NSAIDs (like ibuprofen).

Your vet may also have to cauterize the end of the blood vessels to stop the nosebleeds. If your dog has lost a lot of blood, it may need a blood transfusion, which your vet can provide. Ask about antibiotics or antifungals for infections. If your dog has an infection, a round of antibiotics or antifungals may be needed to treat the infection. Once the infection has been banished by the medications, the nosebleeds should go away, too.

After the bleeding has stopped and your dog has had a plasma transfusion, your doctor may recommend that it begin taking a round of drugs intended to treat the disease.

Your vet may be able to remove the object with tweezers. If they can’t remove the object, they may need to move on to surgery.

Depending on what’s causing the problem, your dog may need other treatments, such as immunosuppressive therapy. Prednisone may be prescribed if the problem has to do with the platelets in the blood. Chemotherapy or radiation therapy may be needed if the cause is cancer. Your dog may also need to stay in the hospital for a period of time for treatment. [12] X Research source

While your dog may still be eating, you should also note if it’s losing weight over time.
