Despite its name, ringworm is not caused by a worm, but by a fungus. The term ring comes from the circular patches that can form anywhere, but are often found on a dog's head, paws, ears, and forelegs. Inflammation, scaly patches, and hair loss often surround the lesions.
Bring your dog to the vet to have him checked for parasites other than fleas. Ringworm and yeast infections can both cause itching in dogs, but you will need to get medication from the vet to treat them.
