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

Now, I know what you're thinking. Isn't Thumbelina officially the world's smallest horse? You read it in the Daily Mail. So did I. Plus her very own website makes the same bold claim. The 17.5-inch (44.5cm) mare has been milking it pretty much ever since Guinness bestowed on her the honour in 2006. She has even done a US tour. But Thumbelina weighed a comparatively hefty 8.5lb when she was born in 2000. And she is officially a dwarf and not merely a tiny version of a proper healthy horse like Einstein, says Rachel Wagner, Einstein's co-owner. Most of the ones that are really tiny are what we call dwarves and have some sort of dysmorphic features. This little guy is like all horses — he's almost all leg, said Wagner, adding, He is very perfect looking little boy and not dwarfy looking at all.
