So, focus on the behavioral changes and symptoms because it may be not as a simple thing as you think and will lead to a serious health problem.

So, let’s find out what the actual causes of dog nosebleeds are and their severity.

What are the common causes of a dog’s nosebleed?

Minor Accidents:

Some minor accidents, like bumping into an object while playing or any other traumatic situation, can cause a dog’s nosebleeds. Nose blood vessels breaking cause this, and this does not last for a long time. But If they show excessive bleeding, then you need to take immediate action to stop it.

Foreign Objects:

In this entire world, there are no other curious creatures like dogs. Besides, a dog’s nose acts as a sensor, which makes it more curious and attentive. So it is a birth habit for them to stick their noses where they don’t belong

Because of this, things like weed seeds, twigs, tiny insects, or other debris could enter the nose and cause damage to the dog’s nose and result in bleeding. Therefore, if your dog shows signs of nose irritation like sneezing or trying to scratch the nose, please pay attention to them before it becomes severe.

Nasal infections:

Dog’s nasal infection or “Rhinitis” results from various factors, such as bacterial, fungal, and viral agents. The nasal infection symptoms vary depending on the underlying cause and severity of the infection.

Nasal Infection Symptoms

  • Breathing difficulties
  • Watery eyes,
  • Swelling
  • Coughing
  • Green, yellow, or watery nasal discharge
  • Bloody discharge in the nose

Please note that it will become dangerous if the symptoms overlap with other health conditions. However, proper treatments and care help to cure nasal infections completely.

Nasal Tumors:

Unfortunately, dogs can develop tumors in their nasal passages, which show bleeding as a symptom. A nasal tumor is an abnormal growth of cells in the nasal cavity or paranasal sinuses. However, all the tumors are not malignant, and non-cancerous tumors are not life-threatening. Only malignant is life-threatening for dogs and the symptoms differ according to the location, size, and type of the tumor.

Nasal Mites:

Nasal mites, explicitly referred to as “Pneumonyssoides caninum,” are a type of parasite that infests the nasal passages of dogs. These nasal mites are not very widespread but they can cause respiratory harm to dogs that are affected by them.

The dog’s nose can be infected by these small parasites that can cause bleeding and irritation, and then move into the respiratory system.

Nasal mites transmission occurs through close contact with infected dogs. Unfortunately, nasal mites infection overlaps with respiratory issues, making it hard to recognize at the early stage. These nasal mites are another reason for the dog’s nosebleeds, which is life-threatening to your dog.

Bleeding Disorders:

Some dogs inherit genetic bleeding disorders which make them prone to nosebleeds.

Dry Air:

Like humans, dogs have delicate mucous membranes lining their nasal passages. As we know, the nasal membranes function as a barrier to dirt and keep nasal tissues moist. In dry environments, nose irritation and bleeding can happen when nasal tissues lose moisture.

So it is necessary to maintain the appropriate level of humidity. To fix this problem, you can easily use a humidifier in dry conditions. In addition, you can use a nose lubricant for your dog as veterinary instruction to avoid a dog’s nosebleeds.

High Blood Pressure:

The normal blood pressure in dogs is 90–160mmHg. (Millimeters of mercury). For some reason, a dog’s blood pressure can be high. When a dog has high blood pressure, it can easily weaken the blood vessels and cause nose bleeding.

Coagulation Disorders: 

A coagulation disorder is a medical condition that disrupts blood clotting ability. The process of blood clotting is crucial to prevent excessive bleeding when injured.

The most common type of coagulation disorder in dogs is Von Willebrand disease (vWD). This is an inherited disorder, and it is caused by dysfunction or deficiency of von Willebrand factor. The von Willebrand factor helps with proper platelet adhesion and clot formation. 

Also, hemophilia and liver disease contribute to coagulation disorder in dogs as well. Coagulation Disorders can diagnosed by doing a blood test. The test measures clotting times and assesses the level of various clotting factors. Hence, Coagulation Disorders are another cause for a dog’s nose bleed, which causes severe damage to your dog’s health.


Some medications can affect normal blood clotting, such as NSAIDs, antibiotics, and anticoagulants. Taking these medications increases the risk of nose bleeding in some dogs.

Some causes for a dog’s nosebleeds are common and may resolve on their own. However, more severe nosebleeds should be evaluated by a veterinarian to determine the underlying cause to recommend treatments.

Apply Pressure:

Using a cloth or gauze, apply gentle pressure to the nostril that’s bleeding. Maintain this pressure for about 5-10 minutes.

In the pregnancy period, the reproductive organs increase the blood flow. This process additionally pressures blood vessels and leads to nosebleeds.

Underlying Health Conditions:

Dogs become more vulnerable to diseases during pregnancy. Therefore, some underlying health issues become more apparent during pregnancy. Therefore, these factors increase the potential nose bleeding in dogs.

Changes in Nasal passages:

Like humans, pregnant dogs face many physiological changes during pregnancy. These changes can affect the blood vessels and mucous membranes in the nasal passages.
