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.
1 In most cases filly is a female horse under the age of four years. 2  In some nations, such as the United Kingdom and the United States, the world of horse racing sets the cutoff age for fillies as younger than five years.he equivalent term for a male is a colt.
