Veteran farrier and founder of the Crawford, Neb., Butler Professional Farrier School, Dr. Doug Butler is credited with saying, “Hoof quality may relate more to the hoof’s ability to regulate moisture content than anything else.” Although Lafayette, Ind., farrier Danvers Child jokes that he and Butler, both members of the International Horseshoeing Hall of Fame, sometimes have disagreements, they see eye-to-eye on this point; the key topic of client discussion should center around regulating the moisture content in hooves.
