If the dog's nose changes from black to pink, liver or even flower nose, it indicates that there is a problem with melanin deposition. Among the causes of dog nose fading, some are caused by diseases, some are completely normal aging process.
1. Season change
Many dogs, such as bixiong, Samoye and other white haired dogs, will also be impressed by melanin precipitation in cold weather, which is the relationship between temperature.
In warm environment, the nose pigment is easy to precipitate; in cold environment, the tyrosinase reaction in the body is slow, and the nose color changes.
There is no need to be nervous. The nose color will change as the temperature rises. As a result, dogs' noses tend to fade in winter, and usually return to black when summer comes.
People call this phenomenon of nose fading in winter "snow nose", because at first people thought that in winter, the snow reflected the sunlight on the dog's nose, which made the nose fade.
This phenomenon, also known as winter nose, is related to temperature and light. In this case, as long as the dog is in good mental condition and there is no other phenomenon, it does not belong to the category of disease. It's a very normal phenomenon.
Of course, we should also pay attention to the dog's diet, and try to give the dog some food that is good for melanin precipitation, or is good for the dog's fur.
2. Aging
This kind of situation is the most normal and not to worry about. Just like people, their hair will be gray and white when they get old. In the process of dog aging, melanin precipitation will be reduced. After the melanin is reduced, the dog's nose will be lighter, and it will not be as black as when he was a puppy.
3. Allergic dermatitis
Some dogs are allergic to plastic products. Contact dermatitis caused by a plastic rice bowl can also cause discoloration of the dog's nose and swelling of the dog's lips. Changing into a stainless steel rice basin will prevent these phenomena.
4. Disease and trauma
A dog's nose can turn pink if it's scratched or scratched. The color will return when the injury is cured. In addition, if the dog has experienced other diseases or psychological trauma, it may also cause nose discoloration. It usually returns to black after the disease is cured.
Leukoplakia can cause discoloration of the dog's nose, but at this time the dog's hair will also have patches of white. Vitiligo, also known as vitiligo, is an immune system disease of dogs. German shepherds, Rottweiler shepherds and other dogs are more likely to suffer from this disease. Improvement in diet can relieve some symptoms of the disease.
5. Lack of nutrition
If your dog usually focuses on the direction of meat, and does not eat vegetables for it, it will also cause the dog's nose color to become light and not black. Vegetables are rich in vitamins, which are good for improving the nose color of dogs.
There is also a lack of some trace element vitamins in dogs, which can easily lead to nose discoloration, generally from deep to shallow, which requires timely supplement of sufficient vitamins and minerals.
However, it is not recommended to use human vitamin products. The content of phycocyanin in natural spirulina is many times higher than that of seaweed powder, which can effectively promote the synthesis of cysteine, i.e. pigment precipitation.
6. During estrus
The dog's nose may also change color during oestrus: the dog's appetite decreases during oestrus, the food intake is not balanced, or the pigment degenerates due to the change of body hormone.
7. Genetic problems
This is a condition that dogs are born with.
So how do you get your dog back to black nose?
Supplement vitamin B and vitamin C. Vitamin B can help melanin deposition, also can make people's hair black, vitamin C can help vitamin B absorption, they are water-soluble, redundant will be discharged with metabolism.
Seaweed powder and salmon oil can also alleviate the fading of nose, and improve the dog's eating BB.
If your dog's nose is completely pink, be sure to protect it from the sun. In foreign countries, the owner can choose whether the dog's nose is black to protect it. Collies may cause ulcers after exposure to the sun, so be careful with sun protection.
