What to do if your dog's hair is not good?

If your dog's hair is not good, you can feed your dog some food and nutrients that can improve the dog's hair, or you can take your dog to get more sun. You can feed your dog carrots. Carrots contain vitamin A, which is important for maintaining hair luster. You can feed your dog an appropriate amount of egg yolk, which can effectively promote the growth of dog hair and nourish the dog's hair. You can also feed your dog seaweed powder, which can prevent the dog's hair from drying out and promote the growth of new hair.
