The pinto stallion named Einstein weighed just 6 pounds and measured 14 inches in height when he was born in Barnstead, N.H. Even though he is a miniature breed, his size is still tiny for a horse.
Dr. Rachel Wagner, Einstein's co-owner, says the Guinness Book of Records lists the smallest newborn horse as weighing in at 9 pounds.
Breeders say that unlike the current record holder, Thumbelina, Einstein shows no signs of dwarfism. Instead, he's just a tiny horse.
