Is this the smallest horse in the world?

A foal thought to be the tiniest horse in the world was born at the appropriately named Tiz A Miniature horse farm in Barnstead, New Hampshire, USA last Friday.

Weighing in at just 6lb (2.7kg) and standing just 14-inches (35cm) tall, the tiny creature, which has been named Einstein, is set to take the crown from Thumbelina, who at 17.5-inches currently hold the title of worlds’ smallest mare.

Einstein’s breeders at the farm are so confident that he is small enough to enter the Guinness Book of World Records that they have uploaded a film of the newborn’s first trip into the paddock and wobbly first steps onto YouTube, with the caption ‘The Smallest Horse in the World.’

Einstein's physical proportions are similar to those of a normal-sized foal, and as Rachel Wagner, one of Einstein’s co-owners, who features in the YouTube video, remarks: "He is very perfect looking little boy and not dwarfy looking at all."
