WHAT IS RINGWORM?
Fungus or ringworm in horses presents as hairless patches with crusty, scabby skin. These lesions are most common on the face, neck, shoulders, chest, or under the saddle or girth, but can appear anywhere on the body. The affected areas may become sore and itchy, though sometimes they cause no discomfort at all.
The organism can survive for months on tack, stall walls or fences and can be hidden on the skin for up to three weeks before signs become evident. During this time, the fungi can be easily spread to other animals and sudden outbreaks may affect every horse it comes in contact with. Left untreated, the lesions will continue to grow and spread.
Although infections might heal eventually on their own, the horse will be highly contagious until they do.
