Seasonal factors of dog nose fading

The color of the nose becomes lighter in winter, and it will gradually turn black in summer, won't it?

This is because the "fragile amino acid oxidase" which affects melanin deposition is very sensitive to temperature and has a stronger effect in high temperature environment, so the nose color is dark in summer and shallow in winter.

Causes of aging and fading of dog nose

Like human aging hair turning white, the role of fragile amino acid oxidase becomes smaller and melanin precipitation will decrease after dog aging. After the melanin is reduced, the color of the dog's nose will become lighter, and it will not be as black as when it was a puppy.

Causes of fading nose trauma and dermatosis in dogs

If the nose is scratched or scratched, the color of the head will become lighter, and the color of the nose will recover after recovery.

Skin allergy, skin fungal infection, etc. If it causes damage to the basal layer of skin, it may also lead to the fading of the alar.

Etiology of autoimmune diseases of dog nose fading

The body will recognize its own melanocytes as "foreign bodies" and produce corresponding antibodies to destroy them.

Leukoplakia, lupus erythematosus and herpes simplex are all autoimmune diseases.

Inheritance of fading causes of dog nose

The dog's nose is not black, or it may be a genetic problem. Because of the diversity and variability of genes, there may also be recessive inheritance. Just because the ancestors didn't have a faded nose doesn't mean that the descendants didn't appear.
