It is normal for dogs to shed hair in summer. Because the weather in summer is relatively hot and it is also the period of hair shedding, a large amount of hair loss will occur. This is a normal physiological phenomenon and there is no need to worry. When your dog loses hair in the summer, it is best to comb the dog's hair 1 to 2 times a day to prevent the hair from falling at home. You should also bathe the dog regularly and deworm it, and at the same time help the dog supplement nutrition so that new hair can grow out. The hair will be healthier.
