Why Is A Dog's Nose Turning Pink

Why Is My Dog’s Nose Turning Pink? Should I Worry?

Your dog’s nose is one of their most powerful tools. A dog relies on their highly sensitive nose to explore the world around them. So when your dog’s nose suddenly changes color from black to pink, it’s understandable to be concerned.

While a pink nose is not necessarily dangerous on its own, the color change can indicate an underlying issue needing veterinary attention. Some reasons are benign, like sun exposure or snow nose. But others may require medical treatment.

This article explores the most common causes of a dog’s nose turning pink, when to see the vet, treatment options, and how to care for a pink nose. Read on to get the facts and determine if your dog needs nasal depigmentation treatment.

An Overview of Dog Noses

To understand why a dog’s nose changes color, it helps to first learn about normal nasal anatomy and pigmentation:

  • Nasal planum – The exposed, hairless part of a dog’s nose is called the nasal planum or nose leather. It contains many blood vessels and nerve endings.
  • Pigmentation – Special cells called melanocytes provide the dark pigment that gives most dogs’ noses their black coloring. This pigment is called melanin.
  • Moistness – The nasal planum contains many sebaceous glands that secrete oils. This gives the leather its signature moist, shiny appearance.
  • Temperature regulation – A dog’s wet nose helps absorb scent chemicals and also cools off their body. Long nasal passages also warm up incoming air.

For most dogs, the nose is made up of black leather, rippled with noticeable grooves and ridges. But some dogs do naturally have pink noses from birth due to their breed, genetics, and lack of melanin.

Why Is A Dog’s Nose Turning Pink?

There is no universal explanation for this, and it could be hard to diagnose exactly the root cause. But there are some commonly accepted reasons why your dog’s nose has become pink.

Seasonal hypopigmentation (commonly known as “snow nose”) is the first thing you should pay attention to, especially when you and your dog live through winter. Some diseases can also lead to this change in nose color.

1. Snow Nose

Your dog likely has a “winter nose” or “snow nose,” a condition that affects many breeds, including Bernese Mountain Dogs, Siberian Huskies, Labrador Retrievers, Labradors, and even smaller dogs like terriers.

Dog snow nose often affects the middle portion of the nose, as well as the pigmentation of the nasal planum. During winter’s shorter, colder days, a naturally black nose may fade into a lighter shade like pink or brown. The dark pigmentation will reappear as the days get longer and the temperature rises again. This alteration in dog nose color is often seen in the winter but may also occur in the summer in tropical regions.

Very little research has been done on this topic, and most of our data is primarily anecdotal. Perhaps the shorter hours of daylight that accompany colder weather have a role.

It is important to note that a snow nose does not alter the moisture or texture of the nose. Only the color changes, often in the center of the nose. If the nose becomes more smooth or has sores, you should visit your veterinarian because there is a high chance of your dog having severe disease.

2. Diseases

While it is less likely to be the case, a pink nose is also a sign of something more serious, such as cancer, immune diseases, infections, or cancer.

They can cause changes in the nose color with a wide range of severity. Some illnesses involve just your dog’s nose, while others affect the whole body, with nasal alterations being just one of the symptoms.

The nose reacts to those diseases and injuries in a few ways. In addition to pigment loss, as you have witnessed, your dog may also suffer from swelling, bleeding, ulceration, or redness. Pain is typically present as well.

Those changes may begin gradually or abruptly, depending on the underlying root cause. They can occur in dogs of any sex, breed, or age.

3. Nasal Depigmentation

Certain autoimmune diseases can attack and permanently destroy the melanocytes in a dog’s nose, leading to complete depigmentation. Systemic lupus erythematosus, alopecia areata, vitiligo, and other disorders can cause melanocyte loss and a pink coloring.

Nasal depigmentation can affect dogs of any age, though it is more common in young to middle-aged dogs. The immune system mistakenly attacks the pigment cells, which cannot regenerate. Some breeds like Pugs, Bull Terriers, and Dogo Argentinos are genetically prone to depigmentation disorders.

It often starts with a small pink spot on the top of the nose, which slowly spreads outward until the whole nose leather is pink. Check for other autoimmune symptoms like skin issues or joint pain and have your vet run blood tests. Treatments aim to stop depigmentation and the underlying disorder.

4. Infection

Bacteria, fungi, or viruses can infect your dog and affect the health and appearance of its nose.

In particular, when a dog’s nose is infected, it can become irritated, swollen, or inflamed. This can cause changes in skin pigmentation and result in pink or reddish nose discoloration.

Some of the most common infections that can cause a pink nose in dogs include bacterial diseases (such as Staphylococcus or Streptococcus), fungal infections (such as ringworm), and viral infections (such as canine distemper or parvovirus).

5. Cancer

Many diseases can turn a nose pink. Cancerous growths on the nose can cause discoloration, swelling, and ulceration, leading to a change in the color of the nose.

For instance, melanomas lead to tumors in pigment cells. When becoming bigger, they may look like pigmented lumps that may begin to bleed or ulcerate. In some situations, however, the tumor may look pink or be amelanotic (lacking dark pigment).

6. Other Causes

Allergies to food dishes and bowls (often plastic), dog food, or allergens may also result in inflammatory lesions and pigment loss.

You may need to research to see what the dog is allergic to. The nose and surrounding region may seem inflamed, painful, crusty, or unhealthy. Typically, the lips are also affected.

Excessive sun exposure may cause bleaching and scorching of the nose, especially in dogs with whiteness pigment. Nutritional deficits may also change the color of the nose and coat.

Are There Any Home Remedies to Repigment a Pink Nose?

While no natural treatment can permanently renourish pigment in a pink nose, some home remedies may provide temporary cosmetic improvement or protect the sensitive skin. Discuss trying any home remedies with your vet first to ensure they are safe for your dog.

Using Dog-Safe Sunscreen

Lacking protective melanin, pink noses are extremely vulnerable to sunburn and solar damage. Apply dog-safe sunscreen to your pet’s nose 30 minutes before going outside. Reapply frequently.

Good sunscreen options for dogs include:

  • Epi-Pet Sun Protector
  • Warren London Pawdicure Polish+Nose Balm
  • Pooch Self Tanning Nose Balm
  • Natural Dog Company Snout Soother

Moisturizing Oils

Massaging coconut, olive, almond or vitamin E oil into the dry nose can help replenish moisture and improve the look of cracking. The oils also provide a mild protective barrier. Apply 2-3 times daily. Avoid petroleum-based oils which may clog pores.

Black Teas

Strong black teas contain tannins that can help stain a pink nose black temporarily. Brew a potent tea, let it cool, and dab it on the nose. Leave for 5-10 minutes then rinse. Reapply daily. Be sure your dog does not lick the tea before it dries.

Aloe Vera Gel

The soothing, hydrating gel from an aloe vera plant may help heal mild abrasions causing temporary pinkness. Apply a thin layer 3 times a day after cleaning the nose. Monitor for any irritation or allergic reaction.


This herb contains apigenin, a compound with mild anti-inflammatory effects that may aid wound healing when applied topically. Gently rub a fresh parsley leaf over superficial scrapes or sores 1-2 times daily.

Licorice Root Paste

Grind up dried licorice root into a paste with water or coconut oil. Licorice contains glabridin, which may help protect skin from sun damage. Apply to the nose 20 minutes before sun exposure. Rinse afterwards.

Colloidal Silver

A few drops of colloidal silver solution applied to the nose twice a day may help speed healing of any sores or abrasions contributing to pinkness. It has antimicrobial properties. Use a cotton swab to apply.

Vitamin E

Feeding your dog more vitamin E rich foods like sunflower seeds, almonds, sweet potatoes, spinach, and broccoli could support skin healing and renewal. Check with your vet on safe supplemental doses.

Charcoal Mask

Mix a pinch of activated charcoal powder with coconut oil into a paste. Apply to the pink nose for 10-15 minutes 1-2 times a week. Rinse off thoroughly. This may help draw out impurities.

While anecdotal evidence exists for these home remedies, there are no scientific studies proving their efficacy. They are unlikely to permanently repigment a nose pink due to depigmentation disorders. But they may provide some cosmetic improvement. Always check with your vet before using home treatments.

Are There Medical Treatments for Nasal Depigmentation?

If an autoimmune disorder, vitiligo, or other disease is depigmenting your dog’s nose, your vet may recommend:

  • Corticosteroids – These immunosuppressants like prednisone help control the immune attack on melanocytes. Long-term use can have side effects.
  • Topical immunomodulators – Prescription tacrolimus or cyclosporine ointments also regulate the immune response. They are less systemic than oral medications.
  • Topical retinoids – Creams containing tretinoin may help stimulate melanocyte pigment production.
  • Oral supplements – Vitamins, fatty acids, and plant extracts (Gingko biloba, ginseng) may help manage depigmentation. Further research is still needed.
  • Phototherapy – Applying targeted UV light to the nose may spark melanocyte activity without skin damage. This is still an emerging treatment. Performed by veterinary dermatologists.

Your vet will tailor treatment using the most effective options for your dog’s diagnosis. Depigmentation cannot be reversed but further progression can be halted. Follow up regularly to monitor effectiveness.

How Can I Prevent Nasal Depigmentation in My Dog?

You can take these key steps to help prevent depigmentation of your dog’s nose:

  • Use dog-safe sunscreen on light noses before sun exposure.
  • Provide shade for your dog outside.
  • Choose plastic food/water bowls to avoid abrasions.
  • Remove sources of irritation like carpet fibers, tall grasses.
  • Gently clean facial folds on brachycephalic breeds.
  • Keep your home and yard clear of toxins or caustic chemicals.
    -Promptly treat any injuries, lesions, or trauma to your dog’s nose.
  • Avoid overusing steroids and medications that can damage melanocytes.
  • Feed your dog a diet rich in antioxidants.
  • Have autoimmune prone breeds tested annually for early disease detection.

While depigmentation cannot always be prevented completely, protecting your dog’s sensitive nose can help maintain their natural coloring. Be proactive in prevention and vigilant about changes.

When Should I Take My Dog to the Vet?

Some reasons for a pink nose are benign, like snow nose on a Siberian Husky. But any sudden color change or abnormal growth merits a vet visit to diagnose the underlying cause. Contact your vet promptly if you notice:

  • Sudden loss of nose pigment vs. gradual change
  • Depigmentation that keeps spreading
  • Crusting, ulceration, bleeding or sores
  • Abnormal lumps, lesions or growths
  • Swelling, redness, or discharge
  • Loss of texture or moisture
  • Immune issues in your dog’s breed

The Takeaway on Pink Dog Noses

While startling at first glance, a pink nose is not necessarily dangerous on its own. It is often an indicator of an underlying issue needing veterinary attention. Certain breeds are genetically prone to depigmentation and color changes.

Dog owners should monitor any nasal color change and be vigilant for abnormalities needing medical care. Protecting pink noses from sun damage and keeping them moisturized can prevent further depigmentation.

Consult a vet promptly to diagnose the reason and determine appropriate treatment. Some causes of a pink nose like snow nose are not serious. But a sudden color change or growths may require immediate treatment. With proper ongoing care and prevention, dogs can live normally with depigmented pink noses.
