After dogs are infected with skin diseases, they will have ringworm on their bodies. These ringworms can be picked off, but be careful not to break the skin when picking. After the dog develops ringworm, it should be treated in time. Clean the scabs of the ringworm, and then apply medicine. If the condition is serious, you can choose to take a medicated bath, so that the recovery will be faster. After the skin disease is cured, new hair can grow.
