Article: If your dog's nose bled or is bleeding it should be taken to a veterinarian. If the bleeding stopped quickly after the sneeze, then you can call your veterinary office, discuss the issue, and make an appointment to bring your dog in. If the bleeding has not stopped or took a long time to stop, then the dog should be taken to a veterinarian immediately, as the blood loss alone can be a threat to your dog's health. If your regular veterinary office is closed while your dog's nose is bleeding, then you should take your dog to an emergency pet hospital in your area. If your dog's nose stopped bleeding shortly after the sneeze, call the emergency pet hospital and discuss whether to bring the dog in or to wait until the dog's normal veterinary office is open. In order to get a diagnosis, your veterinarian will need to do a variety of tests on your dog. These tests, which may require several rounds of testing, will allow your vet to narrow in on the cause of the bleeding. Possible tests your vet will want to perform include:  Blood cell count Urinalysis X-rays Rhinoscopy  Blood pressure Cultures from nose Additional specialized testing There are a variety of things that could be causing your dog's nose to bleed. Once your veterinarian gives you a definitive diagnosis, they should also present you with a treatment plan.  Your dog's bloody nose could have simply been caused by the force of your dog sneezing or by a foreign body in the nose. If this is the case your dog should easily recover on its own once any foreign bodies are removed. However, this may not be the case if there is an underlying problem with the dog's blood clotting ability. Your dog's bloody nose could be caused by a simple sinus infection. A sinus infection is usually treated with a round of antibiotics and can be cleared up quickly.  Your dog's bloody nose could be caused by a tumor. Treatment for a malignant tumor usually includes surgery and chemotherapy, although these treatments can be difficult for tumors in the sinuses.  Your dog's bloody nose could be caused by an infection in its teeth that traveled up into its sinus cavity. If the dog's teeth are infected, your dog will need to go to a veterinary dentist and have its dental infection treated.

What is a summary?
Take your dog to a veterinarian. Approve veterinary testing. Treat the underlying cause of bleeding.
