In general, it can be said that any horse can be trained for riding or driving. However, a special horse type for driving has been bred for many years. The most popular breeds for driving are: Shetland ponies, Trotter, Freiberger, Friesians and Clydesdale.
The breeding-goals for a driving horse are: a stout and powerful exterieur, a rectangular frame, elastic gaits and a slant shoulder to carry the harness well and the horse while keeping an expressive and elaborate trot.
The interior of the horse is even more important when it comes to driving: The horse is supposed to be neither of a nervous or jumpy constitution and should have a balanced and calm nature. He should also be attentive to its environment and have a natural forward drive.
