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.
Baby horses are called foals whether a boy or girl. Baby horses under the ages of 4 are [boy]colts and fillys[girl]. When a horse is over the age of 4 they are a mare[girl or â¦a stallion/gelding[boy]. Geldings are castrated males. Stallions are not castrated, and studs are stallions used specifically 4 breeding.
