STANDISH, ME – SEPTEMBER 24: Ann Melville hot fits a shoe to Falco at Inish Beg farms in Standish, ME Wednesday, September 24, 2014. Hot fitting allows an imprint of the horse’s hoof to mark on the shoe, to give a farrier a guideline for how the shoe needs to be adjusted. Smoke from hot shoeing inhibits a horse’s ability to see clearly, which is why some horses have an aversion to hot fitting. Melville tested Falco’s aversion to the process by producing a small amount of smoke away from his hoof to see how he responded. (Photo by Whitney Hayward/Staff Photographer)
