Happy Horse Essential Horse Hoof Hardener & Applicator helps to support hoof health to keep your horse comfortable. This hoof hardener does double duty—it creates a barrier to help prevent cracking， brittle hooves in dry conditions， and also helps to toughen hooves in wet conditions. You can also use the hardener to fill nail holes and cracks to help prevent fungus from developing within the hoof. When it’s time to head to the show ring， use multiple layers of this hardener to create a high-gloss show-ring shine. No hoof， no horse? No problem!
