The present invention comprises a sock for use on the leg of a horse or ungulate, such as a cow, donkey or other hoofed animal. In the preferred embodiment the sock is tubular in shape having an upper opening and a lower opening. The sock is generally comprised of an upper cuff, main body and lower cuff. The upper cuff and main body are configured to frictionally engage creating a circumferential force on the leg of the horse such that the sock will not easily slip down on the leg of the horse. Expanded knit around the knee joint and fetlock joints allow for the free motion of those joints thus alleviating contrary forces that would normally and otherwise cause the sock to be pulled down by that motion. The lower cuff is configured to expand over said hoof of said ungulate and when over the hoof conform to or hug the small pastern.
