Keratex Mud Shield Powder is a highly regarded, practical and easy-to-use powder that you apply to your horse's feet for a cleansing and waterproofing effect on feet that are prone to blisters, breaks and damaged skin in wet and muddy conditions. This lightweight talc gives your horse's feet a breathable, flexible layer of powder that doesn't absorb water (and therefore won't stick). It also works because the fur on the legs is so silky that the mud can't get stuck to the hair or soften the skin underneath. In addition, it helps the horse's natural defenses against anything from mud and environmental water (such as mud puddles and marshy fields) that could damage the skin and cause problems. This product is widely recognized by the equestrian community as a leader in its field.
