Why is My Pooch’s Nose Changing Color?

Did you know that some dogs’ noses can change color? This can happen suddenly or over a long period of time. Read on as your Sugar Land, TX veterinarian tells you about some of the possible reasons this phenomenon could occur.


Were you aware that dogs can get sunburnt just the way we can? It’s especially likely on areas of the dog that aren’t covered in fur, such as the nose tip or edges of the ears. It’s not uncommon for a dog’s nose to become “bleached out” from too much sun exposure; this is particularly likely if you spend a lot of time outdoors with your dog.

Prevent painful sunburn with a canine-formulated sunscreen. These are available online and in some pet shops and veterinarians’ offices. Ask your vet for a recommendation.

Benign Conditions

Two common but non-threatening conditions can contribute to nose pigmentation color. One is Dudley nose, which causes pigmentation loss for unknown reasons but doesn’t harm your pet in the least. Another is seasonal hypopigmentation, in which a dog’s nose color varies with the seasons. Your veterinarian can tell you more about these disorders and whether or not your dog’s nose color change may be attributed to them.

Food Allergies

Food allergies are another possibility. Dogs may be allergic to an ingredient tin their food, such as pork, lamb, chicken, soy, wheat, or others, or they may be allergic to the specific material their bowl is made out of. The reactions your dog experiences from these allergens may cause pigmentation changes in the nose. You’ll need to set up an appointment at your vet’s office to have your dog examined, diagnosed, and treated.


Fungal, bacterial, or parasitic infection can also cause color changes in a dog’s nose. Of course, infections will also likely cause other health symptoms, most of which are likely to appear before pigmentation changes. Have your dog examined by a veterinarian to diagnose infections of any kind. From there, anti-fungal medications, anti-parasitic drugs, or antibiotics can be prescribed to rid your dog’s body of the infection.

Autoimmune Disorders

Rarely, autoimmune disorders can be the cause of nose pigmentation loss. In these cases, a pet’s immune system mistakenly attacks its own cells, possibly resulting in loss of pigmentation cells and subsequent color change. Your veterinarian can tell you more about this possibility.
