How to tell if your horse has ringworm?


I think my pony has ringworm. How do I tell?

  1. Ringworm in horses is often diagnosed most easily with the application of an iodine solution to the skin. Ringworm lesions typically turn dark blue or black when exposed to iodine, whereas healthy skin turns only slightly darker than normal.

    Ringworm may also be diagnosed through examination of microscopic skin scrapings under a microscope, but this method is not perfect. Lesions are typically found on the lower legs and muzzle or facial area in horses, though they can also be found elsewhere on the body or on other animals that share living quarters with your horse.

    Horse manure that contains eggs – particularly eggs that are less than six weeks old – should always be considered suspect for ringworm infection until all other possibilities have been ruled out.
