Reasons for dog nose discoloration:

1. When the dog gets older, the pigment in the body will degrade, and then the dog’s nose will appear. Color fading phenomenon.

2. If the breeder does not take the dog out to bask in the sun for a long time, the dog's nose will begin to fade after a period of time. This is because there is too little sunlight and the pigment cannot precipitate, causing fading.

3. Seasonal changes can also cause the dog’s nose to fade. In the cold winter, the color of the dog’s nose is not as dark as in the summer.

4. Dogs’ noses often discolor after eating overheated food. When dogs eat, their noses often come into contact with food. When the food is too hot, the melanin on the dog’s nose will be destroyed. Causes nose discoloration.

5. A lack of trace elements in dogs can also cause discoloration of their noses. If your dog is picky about food, you can consider purchasing some trace element tablets to supplement trace elements. After supplementation, the color of your dog's nose will be restored.
