Dogs's noses come in many colors, black, pink, brown, or the same color as their own fur. There are many reasons for fading, some are impure species, some are melanin deposition, some are snow nose, some are heterochromatic nose, some are caused by diseases, and some are completely normal aging process.

The melanin deposition in the dog's nose is melanin oxidase, which is very sensitive to temperature and has a stronger effect in a warm environment, so the dog's nose is easy to fade in winter , to restore black in summer.

Vitiligo

Vitiligo is a disease of the immune system in dogs, which can also cause the nose to fade. Dogs with this condition have patches of white patches on their skin, such as Germansheepdog, Rottweiler shepherd Other dog breeds are more likely to suffer from this disease. Some of the symptoms of this disease can be relieved by dietary supplements.

Snow nose

The phenomenon of nose fading in winter is called snow nose, which is a seasonal decrease in nose pigment. The plane is also the lowest body temperature part of the body, causing the color of the nasal plane to fade. Often occurs in Husky dogs, golden retrievers, Labrador dogs, etc. In this case, usually not all the nose plane is whitened, and the lips, foot pads, eyelids, paws and skin will not turn white, but as long as the dog is in good spirits and there are no other symptoms, it is not belong to the category of diseases.

●Contact allergy

Some dogs are often in contact with plastic food bowls and are sensitive to plastic products, which can cause contact skin inflammation, discoloration of the nose, Even lips are swollen. The solution is simply to replace the plastic rice bowl with stainless steel.

●Dudley nose

Dudley nose may be caused by hereditary, autoimmune or unknown causes. In terms of heredity, it is caused by a dominant circular chromosome defect, such as huskies, Samoyed, yellow labradors, White German Shepherd, Poodle, etc. These dogs are normal at birth and begin to change at 6-12 months of age , The black part of the dog's nose plane gradually fades into a chocolate brown or white color. There is no effective treatment. Some dogs will spontaneously improve or re-pigmentation, but only very few.

●Reduced skin pigment

Reduced pigmentation of mucous membranes and skin This disease is similar to the condition of snow nose and needs to be distinguished. It causes hypopigmentation of the nose plane, lips, eyelids, tongue and mouth, and is prevalent in Australian Shepherds, Huskies, Golden Retrievers and Labrador Retrievers. When the pigment is reduced, there is still enough pigment to avoid damage from sunlight. But if it becomes vitiligo completely, it will be very easy to cause nasal solar dermatitis. Another type of pigment loss that is only in the lips and nose is a hereditary disease in Doberman, Rottweiler, other Breeds can also be sporadic, which is born at birth and the whitening part is fixed, unlike the heterochromatic nose that occurs in mature dogs, which is acquired.

External Injury

A dog's nose can also turn pink if it has a scratch or scratch, or if it has experienced other illnesses or trauma. . The color will return as the wound heals.

How to alleviate the fading phenomenon of the dog's nose?

Dogs should eat dog food as much as possible, supplemented with vitamin B group and vitamin C, trace elements Iron, copper, etc. Vitamin B family can help melanin deposition, and vitamin C is to help vitamin B absorption, they are water-soluble, excess will be excreted with metabolism. Seaweed powder also has a certain effect on relieving nose fading, and can also improve the phenomenon of dogs eating cakes. There is also estrogen that promotes the formation of melanin and appropriately lowers the temperature of food.

Pet owners often feed salty things, meat, ham, canned food, etc., which will lead to a decrease in the dog's vitamin absorption for a long time. It is easy to discolor the nose, skin, and soles of the feet, and eating salty foods can easily cause them to have contact allergies.

Another thing to note is that if the dog's nose is completely pink, then it must be protected in the sun, and it cannot be exposed to the sun.
