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.
Andrew could make this no problem! There are better ways to construct more sturdy and proper cavaletti, but I just wanted a cheap easy fast project requiring limited carpentry skills and with materials I had on hand.
