In general terms, cobs are larger than ponies, standing 14.2 hands or taller, but are relatively small and compact, usually with somewhat short legs. The breed of horse known today as the Section D Welsh cob exemplifies the classic build of the historic cob. It is said that good show cob should have "the head of a lady and the backside of a cook."
Popular uses of the cob include driving, showing and recreational riding. Cob-type breeds have become increasingly popular for Riding for the Disabled Association (RDA), as well as for riders who seek horses who are responsive but with a calm temperament, shorter stature and steady, comfortable gaits.
The rulebook of the British Show Horse Association (BHSA), states: "The Cob is a type rather than a breed. A short-legged animal exceeding 148cms (58 inches or 14.2 hands) with a maximum height of 155cms (61 inches or 15.1 hands), it has bone and substance with quality and is capable of carrying a substantial weight...Cobs should have sensible heads, (sometimes roman nosed), a full generous eye, shapely neck crested on the top, with a hogged mane and well defined wither...The Cob should also have clean, strong hocks and all the attributes of a good hunter.
All sections of Welsh ponies and Welsh 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 11 hands (44 inches, 112 cm) for the smallest ponies to over 16 hands (64 inches, 163 cm) for the tallest cobs.[7] They may be any solid colour, but not piebald, skewbald, (US: pinto)[8] or leopard-spotted.[2] Black, greys, chestnut and bay are the most common, but there are also duns and palominos.[3] However, it should be noted that British equine colour terminology commonly refers to the buckskin colour, which is caused by the same dilution gene that produces palomino, as "dun", but the true dun gene is extremely rare in the Welsh breed.
Their movement is bold and free and characteristically fast, especially at the trot, with great power coming from the hocks.[3] Their trot has been favorably compared to that of the Standardbred horse.[9] They are reputed to be trustworthy, of a good disposition with even temperaments and friendly characters, but spirited and with great endurance,[3] and are known for their stamina, soundness, and high level of intelligence
