There are many reasons for dog nose discoloration. It may be caused by age and lack of pigment. This is a natural phenomenon and we don’t need to worry about it. In some dogs, it may be caused by the weather. The color of some dogs' noses will become lighter when the weather is cold, and the color of their noses will become darker when the weather is hot.

Tip:

The dog’s nose is a very important part. We need to pay attention to its maintenance and avoid giving it any irritating smells.
