| Shetland ponies
Shetland Ponies are hardy and strong, in part because the breed developed in the harsh conditions of the Shetland Isles. In appearance, Shetlands have a small head, sometimes with a dished face, widely-spaced eyes and small and alert ears. The original breed has a short, muscular neck, compact, stocky bodies, and short, strong legs and a shorter than normal cannon bone in relation to their size. A short broad back and deep girth are universal characteristics as is a springy stride. Shetlands have long thick manes and tails and a dense double winter coat to withstand harsh weather. Different breed registries have different height standards, but the outside ranges are between a minimum of 7 hands and 11.2 hands (28 to 46 inches (71 to 117 cm).Shetland ponies are generally gentle, good-tempered, and very intelligent by nature. They make good children's ponies, and are sometimes noted for having a brave character, but can be very cheeky, and, if not handled properly, can be impatient, snappy, and sometimes become uncooperative, traits often lumped under the label "stubborn" by those who fail to understand that pony behavior is influenced by the quality of human handling. Due in part to their intelligence and size, they are easily spoiled and can be very headstrong if not well-trained.
| Thoroughbred horses
Thoroughbred horses are primarily bred for racing under saddle at the gallop. Thoroughbreds are often known for being either distance runners or sprinters, and their conformation usually reflects what they have been bred to do. Sprinters are usually well muscled, while stayers, or distance runners, tend to be smaller and slimmer. The size of the horse is one consideration for buyers and trainers when choosing a potential racehorse. Although there have been famous racehorses of every height, from Man o' War and Secretariat who both stood at 16.2 hands to Hyperion (15.1), the best racehorses are generally of average size. Larger horses mature more slowly and have more stress on their legs and feet, making them more predisposed to lameness. Smaller horses are considered by some to be at a disadvantage due to their shorter stride and a tendency of other horses to bump them, especially in the starting gate.
