When dogs lose hair seriously in summer, you can comb the dog's hair every day to reduce hair loss. You also need to bathe the dog regularly and deworm it to avoid skin diseases. If the dog's hair is relatively long, it can also be cut appropriately. Keep the dog shorter, but don’t shave it bald; try to keep the dog in a cool and comfortable place, which will help the dog dissipate heat; it is best to supplement the dog’s diet with nutrients and vitamins, and do not feed food that is too salty or too oily.
