Things to note during the dog's hair shedding period:

1. The owner should comb the dog's hair many times a day, which can also clean up excess hair and promote blood circulation.

2. Pay attention to bathing your dog regularly, which can also wash away a lot of bacteria.

3. In order to help dogs better maintain their hair and reduce hair shedding, pet owners should also pay attention to regular deworming of their dogs.

4. Every time you bathe and comb your dog, you must use a hair dryer to dry the dog's hair. This can effectively prevent eczema and skin diseases caused by wet dog hair.

5. Dogs need to supplement adequate nutrition when they are shedding, which is good for the dog’s health and the growth of new hair.
