Nasal Pigmentation In Dogs

If depigmentation of the dog’s nose is the current concern of yours, then you are not alone, as the vets get several complaints about their dog developing nasal pigmentation. There are many health conditions in dogs which can change the nose, from simple to even benign. Some diseases limit to the nose area while others can involve the entire body. The depigmentation of the nose represents itself as a symptom of the illness. The nose responds in a limited way when it comes to a disease. Lesions can comprise loss of pigments, pus, scaling, crusting, thickening, redness, swelling, ulceration, and at last bleeding. Pain may or may not persist.

Dudley nose, seasonal hyperpigmentation, commonly called as snow nose is the waxing and waning of pigmented cells with the change of seasons. Less pigmentation will occur during winters and more during the hot summer climates.

Intervention of Microorganisms & some other Factors

When an animal suffers from these conditions, the immune system wrongly targets the right cells, the attachments of cells and pigments. Early detection can prevent long-term side effects for the patient.
