It is possible that it is ringworm but it could also be a bacterial skin infection or an allergic dermatitis. Your vet could do a culture and cytology to determine the exact cause and prescribe medications to treat. He might need an antibiotic, anti-fungal, antihistamine, and/or a corticosteroid to treat.
