Does your horse have skin issues, heated hoofs, colic, etc. Changes in behavior or performance? Now you can find out if these symptoms are due to food or environmental intolerances. We test for all of the major proteins, most grains, fruits, vegetables, the most common trees and grasses, as well as fabrics and materials. We also test for nutritional deficiencies and metal/minerals. No drawing blood or swabbing your horse’s mouth. Just send us a sample of your horse’s mane, tail or body hair and you’ll receive a comprehensive report within 7-10 days after the sample is mailed..
