It is generally normal for dogs to lose hair in spring, because most dogs undergo seasonal hair loss. However, some dogs do not shed hair themselves. Spring hair loss may be caused by malnutrition, skin diseases, or many parasites, and the dog needs to be treated in time. If it is determined that the hair loss is seasonal, you can supplement the dog with lecithin and other nutrients to help hair replacement. Let your dog bask in the sun more. The ultraviolet rays of the sun are also very beneficial to the dog's hair. It can not only promote the healthy growth of new hair, but also play a sterilizing effect and reduce the chance of the dog suffering from parasites.

Methods to deal with dog hair loss:

1. Groom the hair frequently. Grooming cats and dogs regularly can remove their shed hair in time and prevent hair from becoming all over the house.

2. Always bask in the sun. Sunlight can supplement dogs with vitamin D and promote calcium absorption, and ultraviolet rays have a bactericidal effect and can eliminate bacteria on the skin surface of cats and dogs.

3. Supplement nutrition. You need to take in nutrients that are beneficial to your dog’s skin and hair, such as unsaturated fatty acids, sulfur amino acids, and B vitamins.

4. Take a bath regularly. Bathing with pet-specific shower gel can effectively remove old dandruff accumulated on the dog's skin. Wash it once every 7-10 days in spring and summer, and every 10-20 days in autumn and winter.
