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.
Describing a female horse you can use the word mare, or filly for one that is young. A breeding mare is called a dam or broodmare. Young male horses are colts, older male horses are referred to as stallions or studs. A horse that has fathered a foal is called a sire.
