Although cold-blood horses have the same body temperature as warm-blood horses, it is merely a reference to its typically calm, quiet and stable temperament.
Cold-blood breeds are characterized by their heavy body, short muscled neck, large hooves and strong legs, which are often covered by long, feathered hair.
France was the main breeder of the cold-blood horses, and breeds such as the Percheron, Boulonnais, Ardennais and Breton, originated there.
The powerful Belgian heavy draught was also much in demand, and has been used extensively to improve other breeds.
Although cold-bloods once dominated the horse breeding scene, with the huge increase in machinery after world war two, their numbers and of course need, have declined dramatically.
