OK, now that you've done that, take any anti-fungal shampoo you've purchased at your drug store (we use Head and Shoulders Selenium Sulfide Shampoo) and thoroughly scrub each trimmed area (a rolled up pair of women's pantyhose works well).. Rinse well with warm water and then take a quart of warm, clean water and mix in about 1/2 cup (maybe 2 ounces) of common white vinegar. This is where your horse may experience some burning sensation,. Rinse the areas with the water/vinegar and then dry it thouroughly. Finally, use a good, over the counter medication for human athletes foot infections such as Lotrimin, or a 1% hydrocortisone cream and rub well into each area.
Be sure to use latex gloves, since some varieties of the fungus can be transmitted to humans.
Repeat once a week for at least 4 weeks... longer if it persists. Clean up any hair you've trimmed to minimize transmissionto other horses.
Clean as much tack as you can with the vinegar water solution, especially cinches, breast bands and reins, since most infections are on the neck or lower chest areas...
Best of luck!
