A cob is traditionally a draft type pony. Typically of a stout build, with strong bones, large joints, and steady disposition, it is a body type of horse rather than a specific breed. Historically, in the United Kingdom and, to a lesser extent, the eastern United States, a 'cob' may be a common horse used for everyday riding but in the past was used for driving carts.

The Welsh Pony and Cob is a group of four closely-related horse breeds including both pony and cob types, which originated in Wales. The four sections within the breed society for the Welsh breeds are primarily distinguished by height, and also by variations in type: the smallest Welsh Mountain Pony ; the slightly taller but refined Welsh Pony of riding type popular as a children's show mount; the small but stocky Welsh Pony of Cob Type, popular for riding and competitive driving; and the tallest, the Welsh Cob, which can be ridden by adults. Welsh ponies and cobs in all sections are known for their good temperament, hardiness, and free-moving gaits.
