(1.)While there are no legal restrictions on the use of this title in the U.S.A., it properly describes only a professional equine hoofcare expert and shoer of horses. (2.) In the past, farriers were charged with the full range of horse care.
A farrier is a specialist in equine hoof care, including the trimming and balancing of a horse's hoof so as to fit shoes to the horse's foot. A farrier couples a subset of the blacksmith's skills (fabricating, adapting, and adjusting metal shoes) with a subset of veterinary medicine (knowledge of the anatomy and physiology of the lower limb) to address the care of the horse's feet.
