Draft horses are known as cold blooded because of their gentle temperaments. The Clydesdale is a heavy draft horse, an animal bred for the needs of farmers and industry. Their name comes from the River Clyde, which flows through the Scottish town of Lanarkshire, which was once known as Clydesdale. Farmers there desired an especially strong horse for agricultural needs, and industrialialists needed a powerful horse for pulling wagons. Thanks to the well-established breeding practices in Scotland, the breed quickly standardized and the best attributes were maintained. Because of its size and temperament, the Clydesdale has been used to improve several other breeds, most notably the Gypsy Vanner.
