A paddock has two primary meanings in different parts of the English-speaking world. In Canada, the USA and UK, a paddock is a small enclosure used to keep horses. The most common design provides an area for exercise and is often situated near the stables. Larger paddocks may have grass maintained in them, but many are dirt or a similar natural surface. In those cases drainage and a top layer of sand are often used to keep a suitable surface in the paddock. In the American West, such an enclosure is often called a corral, and may be used to contain cattle or horses, occasionally other livestock. The word paddock is also used to describe other small, fenced areas that hold horses, such as a saddling paddock at a racetrack, the area where race horses are saddled before a horse race.
