Solve your horse's healing woes with the Equiderma Zinc Oxide Horse Paste. One of the biggest challenges in getting scratches to heal is keeping the area dry, and this paste does just that by creating a water-resistant barrier. And that's just the first step—taking a three-pronged approach to healing, it also keeps offending irritants off the wound and provides 100% sun protection. UV rays actually inhibit the healing process, so this paste protects your hose from the sun, and it will not come off with normal sweating or rain fall. This is great news for you and the horse, because he no longer has to be kept inside during the healing process.
