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.
Report Abuse. A filly foal is a female baby horse, A colt foal is a male baby horse. Between 1 and 2 years old they then get called yearlings. If a male is castrated it is then called a gelding, if it stays entire it gets called a stallion when it is older. diva Â· 7 years ago.
