all sections of welsh ponies and cobs have small heads with large eyes, sloped shoulders, short backs and strong hindquarters. the forelegs are straight and the cannon bone short. the tail is high-set. the breed ranges from for the smallest ponies to over for the tallest cobs. they may be any solid [[equine coat color|colour]], but not [[piebald]], [[skewbald]], ([[pinto horse|us: pinto]]) or [[leopard complex|leopard-spotted]]. [[black (horse)|black]], [[gray (horse)|grey]], [[chestnut (coat)|chestnut]] and [[bay (horse)|bay]] are the most common, but there are also [[dun gene|duns]] and [[palomino]]s. however, british equine colour terminology commonly refers to the [[buckskin (horse)|buckskin]] colour, which is caused by the same dilution gene that produces palomino, as "[[dun gene|dun]]", but the true dun gene is extremely rare in the welsh breed.
