Ringworms

Ringworm is not a worm - it is a fungus. It often assumes a ring-like, scaly, reddened shape on your pet’s skin. There are three major types, Microsporum canis, Microsporum gypseum, and Trichophyton mentagrophytes. In dogs and cats microsporum are the most common forms I encounter. The groups of three are also referred to as dermatophytes.
