Farriers shoe horses to provide one or all of the above, depending on each horse’s needs. For instance, horses that pull Amish buggies need more traction because they are trotting on the asphalt. Without good shoes that have a lot of traction, a horse may slip on the pavement.Also, you can help a horse move with a better stride at the trot with lighter shoes.here are two ways to shoe a horse: (1) a hot shoe is when the farrier heats the shoe in a cast iron stove and molds the shoe on to the foot and (2) a cold shoeing is when the farrier just applies the shoe without heating it first.
