A FARRIER is a person who shoes horses. They are skilled in the art of horseshoeing, which involves trimming and balancing the hooves of horses, as well as fitting and applying horseshoes. Farriers also provide other services such as hoof care, corrective shoeing, and therapeutic shoeing. Farriers must have a good understanding of anatomy and physiology of the horse's foot, as well as the ability to work with the horse in order to provide the best possible care.
