A white spot on dog’s nose might cause some alarm.  It’s understandable. The nose of a dog is an important part of its anatomy. It is also one of the most visible parts of a dog’s body, as the nose sticks out to the extent that it can be seen from a distance. As a dog owner, I curated information that helped me and will prove useful when your dog gets white spots on its nose that you can’t explain.

What does a white spot on a dog’s nose mean? It can range from something as harmless as a pimple or more severe like kennel nose, fungal/bacterial infection, or DLE, and on rare occasions, Pemphigus foliaceus.

I’ve put together all the relevant information I found and referenced videos below that may help you indicate which state your dog may have, so you can easily consult with your vet if it is serious or not. Read on if you want to know more about this condition with your dog.

What causes white spots on dogs’ noses?

Dog owners are often concerned about the number and size of white spots on their dog’s noses.

Some believe that these spots are caused by sunburns, whereas others claim that freckles cause the spots.

White spots on the dog’s nose are often harmless. Dry skin, allergies, warts, or random occurrences usually cause them.

Although these spots are not necessarily a sign of a serious health problem, you should have your dog examined by a veterinarian if you notice the following symptoms: Your dog has a fever or an elevated temperature.

For milder cases, some veterinarians have some recommendations for possible solutions.

Some vets also recommend that you buy a humidifier and place it in the area your dog spends most of his time in to increase moisture in the air.

Other vets would recommend treating your dog with an antibiotic so their immune system can fight off any bacteria causing potential infection. A drastic recommendation would be to clip off any wart or lesion you find on your dog’s nose, so they don’t spread to other parts of their body.

Note: Make sure to have your dog checked by a veterinarian before starting any treatment.

3 Common types of White Spots On Dogs Noses

Three common spots occur on a dog’s nose, and each has its characteristics. They include:

  1. Tan or brown spots that are either flat or raised. They may also be circular, oval, or irregular in shape. These spots do not bleed easily and can become more noticeable during sun exposure. They are usually painless but are slightly itchy.
  2. Small red bumps resemble pimples on the dog’s nose and accompany redness in the surrounding skin, itching, and inflammation. These can also look like small sores that may bleed when touched too hard. However, most often than not, these sores do not bleed and do not cause any irritation to the dog.
  3. Blood blisters or blisters filled with thick fluid around the eyes of your dog that can get bigger than an inch in diameter. Most often than not, these are painful, especially when touched by your dog’s nose but could also lead to blindness if left untreated for too long.

Other Common Causes of White Spots on Dogs Nose

Snow Nose

The term snow nose describes the appearance of a dog’s nose when it has become frostbitten. It is common in arctic regions but can happen in temperate climates where the temperature falls below 31 degrees Fahrenheit.

Snow nose is more common in breeds with shorter muzzles but can occur in any breed or type of dog. It can affect any dog but is more common in dogs with black noses. Most cases of snow noses occur when dogs ingest snow to cool down on hot days, which lowers their body temperature and causes the blood vessels near their noses to freeze.

Snow nose usually doesn’t cause any pain to the dog, and none can cure it completely. The best way for the snow nose to go away is for the dog’s owner to wait until springtime, so their dog doesn’t have to continue living with a black nose.

Kennel Nose

Environmental factors, genetic predisposition, or other unknown reasons can cause Kennel Nose.

Kennel nose is a common ailment in dogs, particularly when housed in large groups. It’s also called wet dog nose, while it’s called dry dog nose when the dog isn’t showing any signs of nasal discharge.

Abnormal thickening of the skin around the nostrils and eyes characterizes Kennel Nose. Environmental factors such as cold weather, chemicals, extreme temperatures, smoke, and pollution are common causes. Kennel’s nose may also be related to genetic predisposition. It does not seem to be contagious or transmissible between dogs.



A pimple, also “whitehead,” is a raised bump on the skin’s surface. Pimples are usually red and may be painful to touch. If you squeeze a pimple, it will often cause pus or blood to come out because it’s likelier that it’s infected.

The most common causes of pimples in dogs are allergies and bacterial infections, leading to inflammation and scarring.

Some other underlying causes of pimples in dogs include parasites, hormones, medical conditions (such as diabetes), fur mites/lice/parasites, environmental allergens (pollen), food allergies.

Oils also produce pore clogs which can lead to pimples. If a dog has a diet high in fat or oil, this could make a dog’s skin more susceptible to acne issues.

The most common type of acne in dogs is called sebaceous cysts, of which blocked hair follicles are the main cause. These can be popped or drained with an antibiotic ointment or liquid, but if left untreated, the cyst will rupture on its own and may cause an infection.

Dog skin is sensitive, and they are prone to acne. The best way to prevent pimples is by keeping the dog’s skin clean and moisturized with a good quality dog shampoo.

Canine Vitiligo

People first observed canine vitiligo in the 1950s on black labrador retrievers. Most people thought the sun was the main cause, but it is now considered an autoimmune disease.

Vitiligo is a skin condition characterized by white patches of skin on different body parts. The patches are usually round or oval and irregular in shape. The most common spots are on the hands, feet, face, or genital areas, but they can also occur anywhere else on the body.

There is no consensus on what causes this condition; however, some believe it may be related to humans’ autoimmune diseases such as vitiligo.


Discoid Lupus Erythematosus (DLE)

Discoid Lupus Erythematosus is a skin disease affecting dogs and other pets. It is an autoimmune disorder in which the body’s immune system mistakenly attacks healthy tissue, in this case, the top layer of skin. The disease is not contagious.

DLE in dogs usually manifests as a single circular lesion on the skin. A few dogs with this condition may also have lesions on their ears and nose or the ears, nose, and feet. These lesions are often itchy and maybe lightened or darkened in color over time.

It affects younger dogs more often than older ones and males more often than females; it may occur in lighter and darker-skinned dogs; it can be localized (affecting only one area) or generalized (affecting the entire body). The most common symptom of DLE in dogs is scaly, crusty patches of skin on the back and sides of the neck; they usually do not itch or cause pain.


Nasal Hyperkeratosis

Nasal Hyperkeratosis is a condition in which the nose is thick due to excess skin build-up.

The condition manifests with the formation of an excessive amount of keratin on the surface of the dog’s nose.

Some dogs are more susceptible than others for unknown reasons. The most common cause is exposure to extreme heat, such as an air-conditioned room in summer or exposure to fire. Other causes include exposure to substances that contain vinyl chloride, bronchitis, chronic nasal inflammation, and foreign bodies in the nose.

This condition is caused by a genetic mutation in certain breeds, like the Golden Retriever. The disorder does not seem to link to other factors like age, gender, or environment.


Pemphigus foliaceus

Pemphigus foliaceus in dogs is a rare condition that affects mainly bulldogs, Pugs, Shih Tzus, and Maltese terriers. It is uncommon in dogs but more common amongst terriers or terrier-like breeds. It is usually mild and self-limiting, but it may be severe in some cases.

A diagnosis of Pemphigus foliaceus in a dog usually requires a skin biopsy to confirm the diagnosis. The treatment for this condition includes immunosuppressive drugs such as steroids or Cyclosporine A, given orally or intravenously to help the dog control the disease until its immune system is at a level where it can function normally without attacking healthy tissue.


Dog Eczema

The symptoms of canine eczema are also known as atopic dermatitis, a type of inflammation. It can flare up due to allergies or other environmental factors. Many different breeds of dogs have this condition, but it is most common in dogs with certain genetic factors, such as Labradors or German Shepherds.

Canine eczema is not contagious to humans. Symptoms include dry skin, hair loss, redness, irritation, increased scratching, and biting around the area where the skin has broken open, and infections can occur if not treated properly.

Is A White Spot On A Dog’s Nose A Sign Of Cancer?

A black or brown spot on a dog’s nose is just a mark or discoloration and is not indicative of any disease in most cases. Caused by sun exposure and tends to be more prevalent in lighter-colored dogs. If you have a large brown or black spot on your dog’s nose, try keeping him out of the sun for a few days. If this does not help within three days, contact your veterinarian.

A small bump on a dog’s nose is probably just a little infection. If the lump is not painful and smaller than a pea, it should not be cause for concern.

Blood that is coming from the nose is always a cause for concern. If your dog has a bloody nose, it may be from an injury or some tumor or growth in the nasal passages. See your veterinarian as soon as possible if this occurs.

Your dog’s nose can also be affected by allergies. If your dog has a persistent discharge from its nose or sneezing, it may have allergies. If this persists, you should see your veterinarian.

If your dog has a crusty, scabbed up or bleeding nose, you should call your veterinarian. An injury or infection may have caused it.

How do I know if my dog has a nasal tumor?

Although there is no need to panic if you find a bump on your dog’s nose, it is important to have it checked by a veterinarian. As with most things, the earlier the discovery, the better the outcome. If left untreated, a nasal tumor can grow to an unpleasant size and result in other complications such as difficulty breathing and secondary infections.

What are the different types of nasal tumors in dogs?

Two main types of nasal tumors affect dogs: cancerous and non-cancerous.

Non-cancerous tumors occur much more frequently than cancerous ones. These include benign cysts or polyps, inflammatory tumors, and lipomas (fatty tumors).

Benign cysts and polyps are the most common nasal tumors in dogs. Their removal is easy.

Lipomas, also known as fatty tumors, are non-cancerous, and their encapsulation prevents removal.

The two groups of inflammatory nasal tumors are sclerosing adenosis (benign) and Lymphosarcoma (malignant). Sclerosing adenosis looks like cauliflower, while Lymphosarcoma resembles a punctured water balloon.

Depending on their severity, veterinary surgeons can surgically remove both inflammatory tumors.

How are white spots on a dog’s nose diagnosed?

Some breeds are more likely to have respiratory issues than others. Labradors, for example, are prone to snoring and snorting because of their flat faces. Great Danes are also at risk for snoring because of their elongated faces.

A veterinarian may need to do a physical examination and run tests, including blood work, X-rays, or ultrasound, to diagnose what is wrong with a dog’s nose. This process can take a lot of time and cost a lot of money.

If the diagnosis is not clear-cut, the veterinarian may recommend surgery. Surgical procedures can be expensive, but they may also be the only way to determine the cause of the issue.

In these cases, it is best to consult your vet immediately because delaying treatment can make the illness worse and more difficult to treat.

How do I treat a white spot on my dog’s nose?

Skin conditions that may require medical treatment usually cause white spots on dogs’ noses.

Many things can cause white spots on your dog’s nose. Skin conditions like vitiligo, pigmentation disorders, or trauma to the area can cause them. The white spots might also be tissue paper-like material leftover from past infections or injuries to the site.

Can I put Neosporin on my dog’s nose?

Many people would answer this question with a positive answer, but the truth of the matter is that you should not use Neosporin or any other antibiotic on your dog’s nose. Dogs have a more complex system of immunity than humans do, so things that are harmless to humans can have serious effects on dogs. The more topical treatments for dogs would be something like hydrocortisone cream, which will help alleviate some of the inflammation and dryness in your dog’s nose.

What Do Dog Pimples Look Like?

Dog pimples (also called milia) are benign lesions that can occur anywhere on a dog’s skin. These small, red bumps have a black skinhead, and we typically find them around the dog’s eyes, muzzle, or feet. They may also appear behind the ears, near the groin area, and chest. Various factors cause these lesions, including allergies to food, parasites, drugs, or insect bites. Hey usually appear as small red bumps or tiny whiteheads on the skin that “pop” when scratched.

These bumps are called sebaceous glands. They secrete an oily substance called sebum, which helps keep the dog’s nose moist and free of dry skin by preventing the skin from getting too dry.

What should I use to help my dog’s nose dry out?

The best thing you can do for your dog is making sure that he has plenty of fresh air. If it is warm enough, leave the windows open in the house so he can come and go from the fresh air. If it is not warm enough to leave the windows empty, turn on a fan and aim it at your dog’s face. You should also ensure that he stays away from dusty and smoke-filled environments because this will irritate his nose even more. In addition to keeping your dog away from dust and smoke, you should keep your dog away from any other dogs who may have nasal problems. It would be best to wash your dog’s food bowl, water bowl, and any toys in hot soapy water every day.

Do dogs get staph infections in their noses?

Yes, dogs can get staph infections just like humans can. A staph infection will cause a dog’s nose to be very red and swollen and can even cause the dog’s eyes to water excessively. A staph infection will also cause your dog’s nose to become extremely sore to the touch, which is one of the first signs that you need to take your dog to a vet as soon as possible.


A white spot is pretty common for dogs to have.  But when you can’t explain it or is causing your pet discomfort or pain.  Then do not put off a trip to the vet.  It is better to get your dog diagnosed as soon as you can.
