The Clydesdale is a breed of draft horse derived from the very hard-working farm horses of Clydesdale (now Lanarkshire), Scotland and named for that region.
Thought to be over 300 years old, the breed was extensively used for pulling heavy loads in rural, industrial and urban settings, their common use extending into the 1960s when they were a still a familiar sight pulling the carts of milk and vegetable vendors.
At one time there were at least 140,000 Clydesdales known in Scotland; by 1949 just 80 animals were licensed in England and by 1975 the Rare Breed Survival Trust had listed the breed as "vulnerable".
Clydesdales have since seen resurgence in popularity and population, resulting in the breed's status being reclassified favorably as "at risk" with an estimated global population of just 5,000 individuals.
Clydesdales are now more numerous in the United States where recently over 600 foals are reportedly born each year.
