Ringworm on dogs is generally caused by fungi. It can be treated with terbinafol hydrochloride, or antifungal drugs such as itraconazole. Parents are best to choose such drugs specifically for dogs. Don't go to pharmacies to buy human medicine. It is a poisonous medicine. Improper use by parents may cause side effects.

Tips:

Dog ringworm is generally caused by moisture. Parents usually only need to keep the dog’s body surface dry and spend more time in the sun to increase body resistance. You won't get ringworm anymore.
