Some people think a baby horse is called a pony. In fact, a baby horse is called a foal. A foal is a horse that is younger than one year old. A pony can be any age! Ponies have short legs and wider bodies than full-sized horses. Ponies often have thicker manes too! People can ride ponies, just like they can ride full-sized horses.
In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a jenny. A broodmare is a mare used for breeding. A horse's female parent is known as its dam. An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally, the term horse is used to designate only a male horse.
