Why Is My Dogs Nose Bleeding

The two most frequent causes of an acute nose bleed in dogs are upper respiratory tract infections or trauma. You might notice some bleeding from (typically) one nostril if your dog is prone to mishaps or has severe inflammation in his nasal passages from a persistent infection. Rarer causes of bleeding from the nose in dogs include ingesting rodenticide or having a foreign object (such as grass, foxtails, etc.) lodged in the dog’s nasal passages.

While middle-aged to elderly dogs would be more at risk for an autoimmune condition that can cause epistaxis, young dogs who want to explore objects about the house may be more at risk for toxicity-induced epistaxis. Regardless of age, dogs who are left to roam unattended are more susceptible to trauma-related epistaxis.

Epistaxis can also be caused by other, more chronic conditions, such as hypertension, dental infections and diseases, nose growths or tumors, coagulation disorders, fungal infections, issues with blood protein levels, and several diseases transmitted by ticks.

Unilateral bleeding, which occurs when blood comes from just one nostril, is typically caused by a dental infection, a growth on the bleeding side, or a foreign item in the bleeding side. The most common causes of bilateral bleeding, or bleeding from both nostrils, include trauma, upper respiratory infections, and/or fungus infections.

The most common dog breeds to experience Von Willebrand’s illness are Doberman Pinschers, German Shepherds, Golden Retrievers, Miniature Schnauzers, Pembroke Welsh Corgis, Shetland Sheepdogs, Basset Hounds, Scottish Terriers, Standard Poodles, and Standard Manchester Terriers. However, because this condition is inherited, prospective owners of this breed should inquire with the breeder, if buying from one, about the prevalence of this disease in their breeding line.

If my dog’s nose is bleeding, should I be concerned?

Acute bleeding from the nose, nasal cavity, or nasopharynx is known as epistaxis (upper part of the throat that lies behind the nose, just above the soft part of the roof of the mouth and just behind the nasal passages). It is frequently called a nosebleed. Dog epistaxis can be a very disturbing condition for the owner. Most acute or unexpected nosebleeds are brought on by upper respiratory infections or simple trauma. Other, more serious causes of epistaxis in dogs may necessitate prompt medical attention.

What should I do if my dog gets a nosebleed?

You can try the following straightforward first aid measures if your dog starts bleeding from the nose:

  • Be calm around your dog. Excitation-related elevated blood pressure will make the bleeding worse.
  • Put an ice pack over your nose’s bridge (on top of the muzzle). Make sure your pet can breathe around the ice pack if they are short-faced breeds. Small blood vessels will become constricted by the cold, which will lessen bleeding.
  • If your veterinarian has not specifically instructed you to do so, avoid giving your dog any medications.

If using these actions does not stop the bleeding or if the animal is having trouble breathing, you should immediately visit your veterinarian or an emergency facility.

Always keep in mind that a dog with a bleeding nose will probably swallow a lot of blood. This could result in blood clots in the vomit or a black stool (melena) (hematemesis). These observations are typical during an incident of epistaxis and may not always denote gastrointestinal (GI) tract bleeding.

How is epistaxis diagnosed?

Your veterinarian will first ask you for a complete medical history. Relevant details include:

  • Has your dog consumed any medications, including by accident, in the last 30 days? Aspirin in particular, which is an NSAID, can deactivate blood-clotting factors, resulting in spontaneous bleeding. Record all prescription drugs and nutritional supplements your dog has taken.
  • Have you utilized insecticides or rat poison in your house or yard?
  • In the previous two to three weeks, did your dog consume any rats or kill any of them?
  • Has the nose suffered any injuries?
  • Has your dog acted nastily around other animals?
  • Does your dog come into contact with any foxtails, grass awns, or other seed heads that might become stuck in its nose?
  • Has your pet been touching its nose or sneezing recently?
  • Have you seen any bleeding from the gums or from the mouth?
  • Have you seen a stool made of black tar?
  • Have you seen any vomit that is black and “coffee-ground”?
  • Have you seen any strange bruises or skin darkening?
  • Have there been any recent enlargements, lumps, or masses?

After considering the medical history, your veterinarian will do a physical examination. Specifically, your veterinarian will check for the following abnormalities:

  • any imbalance or malformation in your pet’s facial features
  • any swelling on the nose’s bridge
  • the third eyelids are raised.
  • one eye protruding or bulging more than the other
  • severe tears in one or both eyes
  • eyes that are crimson
  • how the skin around the nose looks
  • the appearance of the gums, particularly if they appear pale

What sort of tests may be needed?

Your veterinarian might suggest one or more of the following tests based on the results of the examination:

  • Complete blood count (CBC), which measures platelets and checks for anemia (low red blood cell count indicates blood loss) (cells that are necessary for proper clotting)
  • Blood tests called serum biochemistry are used to evaluate how well organs are functioning, look for signs of toxin-induced liver or kidney damage, or check for any underlying conditions that could result in bleeding.
  • Urinalysis: checking for anomalies such as blood in the urine.
  • Clotting tests are a series of examinations that evaluate how well the blood’s various clotting processes are working.
  • The chest, skull, and oral cavity are frequently radiographed in cases of epistaxis in order to look for signs of internal bleeding or other anomalies that may result in epistaxis.
  • Blood pressure: Bleeding noses can be caused by excessive blood pressure.
  • Tests for antibiotic sensitivity and culture of nasal swabs are used to find any infectious agents.
  • microbial cultures
  • cultures to check for nasal cavity fungal infections

Depending on the preliminary results and health of your pet, more tests may be carried out. Bone marrow analysis, Ehrlichia antibody testing, tick disease tests, sinus and skull X-rays, MRIs, and rhinoscopies are a few examples of further tests (viewing the nasal cavities with a small endoscope).

What causes epistaxis?

Although there are numerous reasons why dogs develop epistaxis, trauma and nasal tumors are the most typical culprits. The following serious conditions can also result in epistaxis:

Is typical dog nose bleeding?

Epistaxis, the medical term for nosebleeds, is never typical in dogs or cats. When they do, they may be immediately followed by secondary shock symptoms and serious bleeding.

What home remedies can I use for my dog’s nosebleed?

The first thought that comes to mind when you see that your dog is bleeding from the nose is usually how to stop it. In the event that there are only one or two drops of blood, you might not need to worry about doing much. However, if there is additional blood, adhere to these instructions to stop a dog’s nose from bleeding:

Remain calm

Whenever possible, try to remove your pet from busy, noisy situations. If you’re at home, especially, try to find a peaceful area. Excitation and stress might increase your dog’s blood pressure and cause more bleeding.

Apply an ice pack to the bridge of the nose

Apply a little amount of ice to the bridge of your dog’s nose after wrapping it in paper towels or a washcloth. You can also use a Ziploc bag filled with ice if you’re in a hurry. Through the local blood vessels’ constriction, the cold will reduce bleeding.

A word of caution

Make sure you are not preventing your dog from breathing by blocking the nostrils with the ice pack if you have a dog with a short nose.

Avoid sticking anything in your dog’s nose

To stop the bleeding, don’t push anything up your dog’s nose. Since individuals use it to treat nose bleeds, I am aware that it can be alluring. However, shoving tissues, gauze, or other items up a dog’s nose might irritate the animal and cause sneezing, which can exacerbate the bleeding.

Follow up with your vet

In order to stop the bleeding and identify and treat the underlying cause, you may need to take your dog to the emergency vet if the bleeding is severe, lasts for more than a few minutes, or exhibits any other symptoms of disease or injury. Even if you manage to stop the bleeding and your dog appears to be in good health, it is typically still a good idea to visit your veterinarian during office hours. In this manner, your veterinarian can perform any necessary tests to assist in determining the cause of your dog’s bloody nose.

What results in a single nostril nosebleed?

The majority of nosebleeds are anterior, which means they originate just inside your nose, from the lower septum, the wall between the two channels of your nose. The Little’s region of the nose is home to numerous tiny blood vessels that are readily broken.

Although the etiology of anterior nosebleeds is occasionally uncertain, they can be brought on by a variety of factors, such as:

  • picking your nose, especially if you use a sharp fingernail to scratch the inside of your nose
  • firmly blowing your nose
  • some slight nose damage
  • an infection, such as a cold or flu, that frequently results in a clogged or stuffy nose
  • Infection of the tiny, air-filled spaces in your cheekbones and forehead is known as sinusitis.
  • Dry air or a rise in temperature might cause your nose’s interior to become dry.

Can dry air cause nosebleeds in dogs?

Since Valentine’s Day was observed this week, it should serve as a reminder of the loved ones and pets in our lives. So, I must talk to you about something that makes my heart ache in memory of one of mine that I loved and lost. My beloved standard poodle, Peyton, is well known to those of you who have read my posts. She passed away from nasal lymphosarcoma nine years ago, and I still miss her.

There are numerous causes of nosebleeds in humans. The Mayo Clinic lists dry air and picking your nose as the two most typical reasons. Nosebleeds may result from allergies. Nasal bleeding can also be brought on by sinus infections, drugs (such as aspirin and blood thinners), deviated septa, and polyps.

Conversely, DOGS DO NOT HAVE NOSEBLEEDS! A dog’s nosebleed is always caused by a significant issue. It goes without saying that traumatic causes are quite simple to identify. Dogs occasionally receive foreign objects in their nostrils, which can cause bleeding. Other factors include bleeding issues and systemic hypertension. Systemic hypertension is not typically recognized as a major issue, but if it is present and linked to chronic renal illness, symptoms of the underlying condition, such as increased urination and water intake, should help us identify the source of the nosebleed. Bleeding problems are rare, but they frequently manifest in young animals since they are initially identified during an ovariohysterectomy or neuter.

Cancer, sadly, is the second most common cause of nosebleeds. When my beloved Peyton sprang from the grooming table, she bled a little from her nose. I put her to sleep right away and scoped her nose (this was before I had my CT, or I would have performed that test as well). Her nose had a shimmering white tumor, and the biopsies revealed lymphosarcoma. Before giving up the fight after 14 months of valiant effort.

I want to demonstrate what nasal tumors are like on CT scans. The dog in the first set of pictures has been experiencing nosebleeds on and off for three months, even though the first one actually happened a year ago. The septum was obliterated. The eye’s orbit has been obliterated. There is a tumor visible in the brain, and the cribriform plate separating the nose and brain has been damaged. This dog’s face showed no signs of the tumor, as you can see.

The following pictures show a dog who has experienced nosebleeds for a year (Lucky Reid). A malignancy in the left nasal cavity has destroyed the typical turbinate bone structure of the nose.

The final pictures show a dog who has previously experienced nasal congestion (talk about a sharp owner spotting an issue!). There is an aggressive right-sided nasal tumor that has crossed the midline and entered the left nasal cavity (Pilot Bennett).

I hope you can see from some of these photos how sensitive CT is for finding nasal cancers. If your dog develops a nosebleed, please don’t let him go. I sincerely hope none of you have to treat a loving pet for nasal cancer. It is time to get a referral for aggressive diagnostics because this is NOT normal.

Do nosebleeds result from dehydration?

Typical Reasons for Nosebleeds Bloody noses are rather typical. They can be brought on by a number of things, such as dehydration. Dry, chilly air.

Can dogs sneeze and have nosebleeds?

Numerous factors, including sneezing brought on by allergies, infections, foreign objects, polyps, and bleeding disorders, can cause nosebleeds in dogs. While ultimately you’ll need to determine the cause of your dog’s nosebleed, your immediate goal should be to stop the bleeding. For that:

  • Keep your dog calm and soothed.
  • Use something absorbent to cover the bleeding nostril.
  • In the region above your dog’s eyes and nostrils, apply a cold compress.
  • Don’t put anything inside your dog’s nostril or bend its head back to slow the blood flow.
  • If bleeding does not cease in a few minutes, contact your veterinarian right away.

Why sneeze blood when a dog is old?

A simple “Bless you” could stop this kind of sneeze, we wish! However, if your dog is sneezing blood, you should get them checked for an underlying issue, such as debris like grass awns or foxtails lodged in their snout. Bloody noses can also be brought on by bacterial infections, fungal disorders, or even nasal tumors.

Keep your dog quiet and relaxed to lower their blood pressure, which can therefore slow the blood flow to their nose, which can help stop a nosebleed at home. If your dog agrees, you can apply pressure or perhaps some ice on the nose’s bridge.

What are the top 3 reasons for nosebleeds?


  • Chronic sinusitis (nasal and sinus infection)
  • Allergies.
  • using aspirin.
  • bleeding conditions like hemophilia.
  • Anticoagulants that thin the blood, including heparin and warfarin.
  • irritating chemicals like ammonia.
  • persistent sinusitis
  • using cocaine.
