Dog Nosebleeds: Causes & Care Guide (Vet Answer)

We all know that people can get nosebleeds for various reasons, but what about dogs? Can dogs get nosebleeds? Yes, they can. If you have ever had your dog run up to you with a nosebleed, it’s easy to panic, and you’re not alone. Let’s dive into some potential causes of nosebleeds in dogs and what you can do about it.

What Is a Nosebleed?

A nosebleed is just like it sounds: blood coming from one or more of the structures in the region of your dog’s nose: the nasal cavity itself, the nostrils, or even the nasopharynx. This condition is also referred to as epistaxis.

What Are the Signs of Nosebleeds in Dogs?

Nosebleeds can appear in a few different ways. You might see blood coming from one or both nostrils. It can be a couple of drops that you notice when your dog sneezes, or significant amounts of blood could run out of your dog’s nose.

If your dog has a condition that causes generalized bleeding or difficulty clotting, you could see other signs:

You might notice facial deformities with certain conditions, such as nasal tumors or even fungal infections.

Because dogs with nosebleeds may swallow the blood, you might see evidence of that blood in vomit or stool. The stool may look dark and tarry, generally referred to as melena. Vomit could have blood clots in it or look like coffee grounds.

What Are the Causes of Nosebleeds in Dogs?

There are a range of different things that could cause epistaxis in dogs. The two most common tend to be nasal tumors, which may not be readily apparent on physical exam, and trauma. Nasal tumors make up roughly 1% of all tumors in dogs.¹ They can cause deformities of the muzzle.

Some of the potential nasal tumors include:

Conditions affecting the nasal cavity can contribute to epistaxis. If your dog gets a tooth root abscess or an oro-nasal fistula in the maxilla or upper jaw, it could cause bleeding into the nasal passages. These conditions may be evident on a physical exam or under anesthesia, but your veterinarian may need diagnostic imaging, such as dental radiographs (X-rays), to diagnose them.

Dogs like to use their noses to investigate the world around them. Unfortunately, that can increase the odds of a nasal foreign body, such as a grass awn or foxtail. These objects may be quite tiny but can migrate through the tissues and cause inflammation and bleeding.

Disorders that contribute to bleeding or trouble clotting are associated with nosebleeds, including:

Infections affecting the airways, such as bacterial or fungal infections, may cause nosebleeds.

Other infection possibilities are:

Certain rodenticides (rat poison) can cause bleeding. Drug reactions could also cause an issue. Even something as commonly used as non-steroidal anti-inflammatory drugs (NSAIDs) could cause bleeding.

Diagnosing a Dog With Epistaxis

If your dog presents with a nosebleed, your veterinary team will first try to make sure he is stable. They’ll perform a physical exam and ask you questions. Some of the ones you might get asked are:

Some of the diagnostic tools your veterinarian may recommend include:

How Do I Care for a Dog With Nosebleeds

There aren’t many home therapies for dogs with nosebleeds, and you should have your pup evaluated by a veterinarian as soon as possible, especially with significant amounts of blood coming from the nose. But first, you should calm your pet to try lowering their blood pressure. Excited or stressed pets with higher blood pressure will likely bleed more. VCA Animal Hospital recommends putting an ice pack on their muzzle, as the cooler temperature will help constrict blood vessels.

At the veterinary hospital, your veterinarian will assess your pet and come up with a tentative diagnosis. In addition to controlling bleeding, your vet will look to treat the underlying cause. For example, they might recommend:

Dogs with chronic or recurrent nosebleeds may benefit from an herb called Yunnan Baiyao. Talk to your veterinarian before administering it to see if they think your pet might benefit from it.

Your pet may need a thorough oral exam performed under heavy sedation or anesthesia. If dental disease is noted at that time, your veterinarian may be able to treat the diseased teeth or refer you to a veterinary dental specialist. Additionally, your dog may require blood or platelet transfusions, depending on how severe the bleeding has been.

Frequently Asked Questions (FAQ)

How does liver disease cause nosebleeds?

In the later stages of liver disease or failure, the liver loses the ability to create clotting factors. Without these components in the bloodstream, your dog’s body cannot adequately stop bleeding.

Can heat stroke cause a nosebleed in dogs?

Yes, if your dog develops heat stroke, they can develop a nosebleed. Unfortunately, this phenomenon typically occurs with severe heat stroke when your dog’s body is going into disseminated intravascular coagulopathy.

Conclusion

If your dog develops a nosebleed, they need to be evaluated by a veterinarian as soon as possible. Identifying the underlying cause of epistaxis is important so that your veterinarian can treat it effectively, which may involve in-depth diagnostics. Ultimately, the prognosis for your dog will depend on what the cause is, as well as your pup’s response to treatment.
