6-pound foal born in NH may be world's tiniest.

A diminutive horse born in New Hampshire could lay claim to the world record for lightweight foal. The pinto stallion named Einstein weighed just 6 pounds and measured 14 inches tall when he was born Friday in Barnstead, N.H. Those proportions fit a human baby just about right but are downright tiny for horse, even a miniature breed like Einstein.

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. He's just a tiny horse.
