Miniature: The smallest breed in the world, minis are so small that some are even allowed in homes; like cats and dogs!
Shetland: Small, strong and sooooo incredibly adorable, these ponies are (sometimes) great little kids ponies, that is, if they're good tempered.
Welsh: Probably the most popular childrens' pony, these little bundles of energy are athletic and affectionate, making them the ultimate kids pony!
Connemarra: These little sweethearts are quite shy, but if they're loved to bits, they'll do anything for you!
Quarter Horse: Recognised as the most popular horse breed in the world, Quarter horses are super speedy and super fun, and they earn the name "Quarter" horse because they can run a quarter mile faster than any other horse!
Thoroughbred: Most commonly known for being used as race horses, thoroughbreds are stunning, muscular and glossy, but watch out, they can have an attitude, so basically, they're the divas of the horse world.
Morgan: Beautiful, elegant, graceful; these beautys are simply a treat, both in and out. If you own one, you should be REALLY happy with your life.
Friesian: Big and black, these horses are spectacular! With long, wavy manes and tails, these funeral horses know how to strutt their stuff!
Clydesdale: These gentle giants wouldn't hurt a fly! Unlike the massive, stocky Shire, Clydies have long, dainty limbs and bodies.
Shire: The biggest horse in the world, Shires are big, powerful and stocky cold-blooded horses. You can sometimes see them pulling carriages.
So, you decided? Is it the cute little mini, or great and powerful Shire? Maybe you decided the mighty Morgan, or the fantastic Friesian? They're all amazing in their own way. :)
