Book excerpt: In this follow-up to her best-selling Understanding the Horse's Back, Sara Wyche turns her attention to the legs. Although often taken for granted, it is self-evident that healthy, strong legs are essential for successful riding, whether for leisure or in competition. Topics covered included the anatomy of the horse's legs; likely problems from hooves, joints and bones, muscles, tendons, and ligaments; causes of lameness; and advice on care and treatment including homoeopathic and alternative remedies.
