Dogs
Many owners will find that their dogs' noses are discolored. However, This kind of fading is not safe. After a while, the dog’s nose will turn black again. What exactly is happening?
There is a theory that it is caused by feeding it sweets or worms. This is not supported by medicine. Pigmentation on the skin is a psychological phenomenon to hide the sun's rays and protect the body. When exposed to the sun, the amino acid system and its development mechanism in the melanocytes deep in the epidermis make the melanocytes acidified and turn black due to the action of enzymes. They are then transported to the epidermis by the pigment-organizing cells, causing melanin to precipitate. To prevent scabies, the dog must sunbathe, and feed the dog meat and beef liver rich in amino acids, perilla, roots and leaves, carrots rich in carotene, and seaweed rich in iodine.
