The reasons for sparse Pomeranian hair:

1. As Pomeranians age, their hair growth rate is much lower than the rate of hair loss, resulting in hair degeneration. Very rare.

2. Excessive exposure to ultraviolet rays can also cause Pomeranian hair to become thinner.

3. Bathing your Pomeranian too frequently can also lead to sparse hair.

4. It may also be that the Pomeranian is infected with a skin disease, causing the hair to fall out and become sparse.

Solutions for sparse Pomeranian hair:

1. If you have skin disease, you must treat the skin disease symptomatically.

2. You can also feed lecithin to dogs, coupled with nutritional paste, to increase the dog’s nutrition.

3. If the hair is dry, you can also use some hair and skin repair agents.
