The World's Smallest Horse, Einstein, Is Bundle Of Energy

When he was born in New Hampshire on Friday, young Einstein weighed just 6lb (2.7kg) and stood a mere 14-inches (35.5cm) tall. It is traditional to patronise small things by describing them as being pint-sized. Having spent some time cooing over this video of Einstein gambolling around his paddock to a rather charming bluegrass soundtrack, I have concluded he is at least two-litre-sized. But no matter. His breeders on the Tiz A Miniature horse farm in Barnstead, New Hampshire, in the north-east US, are confident that he is small enough to enter the Guinness Book of World Records.
