While ringworm is not a worm, it is characterized by circular or elliptical patches of hair loss that may appear crusty, red, and inflamed. This condition can affect dogs of all ages, sizes, and breeds. The exact cause of ringworm in dogs is unknown to vets, but they believe it may be spread through direct contact with an infected dog or by coming into contact with contaminated objects or surfaces.
