In this article, you’ll learn more about dog’s depigmentation or the 3 main reasons dogs lose their pigment around the nose and mouth, the two most commonly affected and easy-to-notice areas. Also, the treatment for each reason varies due to the seriousness level of the symptom and disease.

Let us walk you through.

3 Reasons Dogs Losing Pigment Around Mouth and Nose

More likely to humans, the skin color of dogs also depends on melanocyte cells in their skin. Melanin in those cells will determine the color of the skin. Different kinds of dogs come in different shades. However if your dog’s skin suddenly loses its original colors and starts getting depigmentation, this may result from some health issues.

1. Discoid Lupus Erythematosus

Discoid Lupus Erythematosus (DLE) is a common skin problem, also known as an autoimmune disease. Autoimmune happens once the immune system attacks normal cells within the body and causes inflammation.

What causes DLE and its symptoms?

The main reasons for DLE are still unknown but it’s believed that genetic, environmental, and hormonal elements play a significant role in the form of lupus.

Dogs with DLE typically show some abnormal signs on the areas of the face, nose, mouth, ear, or around the eyes. You should keep an eye on the following symptoms:

  • Discoloration skin on the bridge of the nose
  • Skin, nose, lip’s redness
  • Itchiness at the affected areas such as nose or face
  • Flaky or scaly skin

DLE treatment

In general, DLE is diagnosed as a less severe disease. But till now, there is no certain medicine that can 100 percent cure DLE.

The symptoms of DLE often come and go for a couple of months. However, if the situation gets worse, veterinarians might suggest using corticosteroid drugs combined with Vitamin E supplements.

DLE symptoms may get more serious when exposed to sunlight. So dogs with DLE should avoid sun exposure to the minimum. Applying sunscreen is also recommended if your dog(s) has to be housed outdoors. If not, it would be better to walk them in the early morning or late evening to reduce the potential of direct exposure to UV light.

2. Vitiligo

Vitiligo is another abnormal skin condition when the dog’s skin loses its natural color or depigmentation. In some cases, darker coated dogs have their hair also turn white partially or entirely. You also notice white spots on your dog’s nasal planum or the inner lining of the lips.

What causes Vitiligo?

Melanocytes are the cells in charge of producing melanin in the skin. Once the melanocytes are damaged or die off, vitiligo will occur.

It’s still unclear why vitiligo actually happens in some dogs but in most cases, vitiligo in dogs and cats is hereditary. If your dogs’ breed is Rottweilers, Yellow Labrador, German Shepherds, Old English Sheepdogs, Siberian Huskies, or Dachshunds, they are at high risk of developing this type of skin disease.

Autoimmune, stress, or exposure to toxins are also believed to cause vitiligo in pets.

Vitiligo treatment

Currently, none of the treatments for vitiligo will ensure re-pigment of the affected areas like skin or fur. However, several management options veterinarians can recommend for vitiligo such as increased sun exposure time to enhance the production of new melanocytes.

In case your dog is under stress, try to make a less stressful environment at home or use meditation if needed.

Along with that, adding omega-3 acid and vitamin C to your pet’s diet proves they manage vitiligo pretty well. In fact, vitiligo doesn’t cause any discomfort to your dog and cat, it's just a matter of cosmetics.

3. Other Conditions

As a matter of fact, there are millions of other reasons that could cause pigmentation or discoloration in dogs. In some situations, the reason may come from very small things that you would never imagine.

A plastic bowl is one of them. A lot of dogs reported allergies and suffered losing pigment when eating plastic bowls for a long time. The plastic chemical affects the dog's lip and nose color.

If you notice your dog's bottom lip or top of the nose turn white or have some white spots, there’s a high chance of the reason from their dish.
