First of all, you need to buy a comb specifically for pets. Choose a long-toothed comb for long hair, and a short-toothed comb for short hair. When combing your dog's hair, you can comb it along or against the hair, or in a circular motion. Pay attention to this. Just don’t use force on your hands that hurts the dog. Brushing your dog's hair regularly helps the dog's hair grow, removes floating hair on the body, reduces hair loss, and makes the dog's appearance tidier.
