The dog's nose is an important signal to reveal the dog's physical condition, and a moist and shiny nose is a sign of a healthy dog.

First of all, black nose

Black is the most common color of dog's nose. Dogs, like us humans, have melanin in their skin, but there is no hair in this part of the nose, and more melanin is needed to resist the damage of ultraviolet rays to the skin, so melanin is deposited here.

Myth: Just because a dog's nose is not black doesn't mean it's unhealthy. The color of the nose is influenced by genetic factors and acquired factors, and the color of the nose is not immutable.

Second, a white nose.

Genetic factors: the nose fades due to genetic factors, and the skin has no inflammatory changes except pigment changes, and it is not life-threatening except affecting aesthetics.

Common breeds: mainly in light-colored dogs, such as Labrador, Golden Retriever, Husky, Samoyed, etc.

Weather factors: it is "fragile amino acid oxidase" that affects the melanin deposition in the dog's nose. It is sensitive to temperature and has a stronger effect in warm environment, so the dog's nose is easy to fade in winter, and it usually turns black when summer comes.

Age factor: the dog is too old, and the secretion of melanocytes in the body decreases, which leads to the color of the dog's nose becoming lighter and whiter.

Nutritional factors: long-term lack of vitamins and trace elements leads to decreased melanin deposition in the skin.

Nutritional components related to melanin formation are:

Amino acids: tyrosine, tryptophan, lysine, pantothenic acid, folic acid, biotin, p-aminobenzoic acid.

Vitamins: vitamins b, c and e.

Trace elements: copper and zinc. The above nutrients can be supplemented by seaweed powder, soybeans, lentils, mung beans, red beans, peanuts, walnuts and black sesame seeds.

Third, a (red) brown nose.

Dermatosis: Because mites or fungi destroy the epidermis and dermis of the skin, melanocytes can't have biochemical reactions, so local skin will turn red. If the skin layer damage is not serious, the color of the dog's nose will return to normal in the later period.

Exclusion or malnutrition: there is a lack of trace elements and vitamins in food, because some of these nutrients are the main nutrients for melanocytes to convert melanin, and some are the main nutrients for maintaining skin health. Without these nutrients, the dog's nose will not be so black, but turn reddish brown.

Treatment: You can appropriately supplement some foods containing vitamins and trace elements. Chicken liver (iron, vitamin A), chicken breast (copper), seafood (complex acid), seaweed powder, etc.

Fourth, gray nose.

Dog aging: with the increase of dog age, the metabolism of organs and body will slow down, and the melanocytes in the nose are no exception. The metabolic function of transformation begins to decline, and the melanin transformation is not complete, and peeling and cracking will occur.

Five, dry nose

If the dog is found to have not only a dry nose, but also symptoms such as cough, drowsiness, vomiting or diarrhea, and even general fatigue and loss of appetite, then the dog is probably sick, and the following diseases will cause the dog to have a dry nose.

1, sunburn: dry nose, redness or peeling nose skin. Dogs with pale or pink noses are particularly prone to sunburn.

Treatment: Ask the doctor to prescribe some special lotions that are not damaged by sunlight, because repeated sunburn can easily lead to skin cancer in dogs.

2, skin diseases: dry nose, scabbing or sores, may be caused by skin diseases.

Treatment: Go to the hospital for examination and prescribe the right medicine.

3, severe dehydration: dry nose, sunken eyes, dry gums and skin elasticity loss and other symptoms.

Treatment: Give the dog enough water immediately.

4, allergic problems: because allergies lead to lacrimal passage blockage, then body fluids can not reach the nose, resulting in dry dog nose.

Treatment: Go to the hospital for examination and prescribe the right medicine.
