Breed of heavy draft horse that originated in Lanarkshire, Scotland, near the River Clyde. Though introduced to North America c. 1842, the Clydesdale never became a popular draft horse there. They average 17–18 hands (68–72 in., or 173–183 cm) in height and 2,000 lbs (900 kg) in weight. Their coloration is usually bay, dark brown, or black, with prominent white markings. They are noted for their high leg action while walking or trotting. The breed is characterized by feather (long hair) on the legs, an attractive head, and well-formed legs and feet.
