Meet The Adorable Miniature Horse – And Yes, They Are Fully Grown (16 Pics)

What's the Difference Between Mini Horses and Ponies? To the layperson, Miniature Horses and ponies may appear to be one in the same. Both are just little horses, right? Not exactly. First Things First. Merriam-Webster defines pony as a small horse; especially one of any of several horse breeds of very small stocky animals noted for their gentleness and endurance. The same dictionary defines Miniature Horse as… nothing, actually. There is no listing for miniature horse. Commence the head-scratching.
