Solutions to the lightening of Teddy's coat color:

1. Dogs with lightened coat color can be given timely supplements of trace elements and vitamins to improve their hair.

2. Give the dog enough light time, and at the same time supplement skin nutrients, such as unsaturated fatty acids and lecithin, to promote hair growth.

3. You can also solve the problem of lightening of Teddy's coat by combing it. Combing helps blood circulation and metabolism, and promotes hair beauty.

The reasons why Teddy’s coat color becomes lighter:

1. Due to the poor quality of the dog’s own hair, the color of the hair will become lighter and lighter with age.

2. Excessive salt intake in the dog's body will cause the quality of the hair all over the body to decrease, and the color will become lighter and lighter.

3. If you often go out for walks or exercise without taking your teddy, and if you are not exposed to sunlight for a long time, your teddy’s hair will naturally become lighter.
