A dear friend recommended that I call June. June had been her trimmer for awhile and my friend was thrilled with the improvement in her own horse's feet since June started visiting her farm. I called and June began to trim Amber as she believed to be correct and natural. I learned that it was not white line disease, it was actually a case of her poor hooves not being trimmed short enough. Over 3 years her toes had been allowed to grow gradually ever so long by her previous trimmer. Each trim, more and more hoof was not being taken off. Towards the end of the situation, the trimmer was taking of a tiny edge around the hoof, leaving the giant crack in the middle for me to "keep cleaning". Simply put, not enough hoof was being taken off. The hoof wall was splitting in the middle to adapt and relieve the leverage pressure on the top of her foot.
Fast forward 2 years, and Amber has the nicest hooves on the block. Her feet are appropriately sized, healthy, and NO CRACKS! It has been an amazing turn-around, with a happy ending. Thanks June! October, 2015
