For 2 years, I could not get my horse’s mane/tail to grow. I tried all sorts of supplements, special shampoos, conditioners, etc., nothing worked. Then I tried Hoof and Hair Guard Supplement and in less than 20 days, I could see a HUGE difference. Even during the winter months when it’s extremely cold and hard to keep strong mane/tail growth, Horse Hoof and Hair Guard keeps her mane/tail healthy, her hooves strong, and her thick coat shines. It’s a miracle worker! I also love how Horse Guard is a local business to where I live. It’s nice to be able to support local companies. Especially the ones (Horse Guard) that provide quality products. Thank you Horse Guard for making excellent products that really work!" -Kayce Little Feeding Instructions: Feed 6 ounces per day, top-dress over grain, and/or combine with other supplements.
