This is Einstein - possibly the smallest horse in the world. Born in New Hampshire, USA, this tiny coloured stallion measures 14 inches tall and weighed only 6lbs when he was born. That's smaller and lighter than an average human newborn baby.
Einstein was so tiny that his owner thought initially he was dead "I've been at this for 20 years plus but I've never seen one this tiny or even close to it,".
Unlike many miniature horses Einstein shows no sign of dwarfism – as does the current claimant of the world's smallest horse title, Thumbelina.
Einstein's co-owner Dr Rachel Wagner said "Most of the horses that are really tiny are what we call dwarves and they have some sort of dysmorphic features, or features that aren't really normal or healthy. This little guy is like all horses - he's almost all leg.' The Guinness Book of Records lists the smallest newborn horse as weighing just 9lbs.
