Tink had major surgery to her hoof due to an infection down to the bone. After trying another supplement with little results, we switched to Hoof Secret. The speed of recovery was amazing. The veterinarian said it was growing at least double the rate and the healing process from the inside out was outstanding. Her hoof is in excellent condition now and has no signs that she ever had anything wrong! I would recommend this product to anyone who wants their horse’s hoof in top notch shape.
