Question: what is the difference between a small horse and a pony?
Answer: Ponies remain small when they're fully grown. ... The main distinction between ponies and horses is height. A horse is usually considered to be an equine that's at least 14.2 hands (or about four feet ten inches) tall. A pony, on the other hand (pun totally intended!), is an equine less than 14.2 hands.
