Horse breeds: The falabella ponies are the smallest know to man, reaching to only about 3 ft. Tall when fully grown! Pony of the Americans is a awesome horse for kids. They have a perfect slope in their backs so it's easy to stay on, even bareback.
Rare Twin Horses- when my mare& ultrasound showed she was having twins, the vet when in and pinched one of the embryos off so one could survive. Twin horses usually do not go full term and are born too early to survive.
