A tiny horse measuring just 35cm tall is thought to be the world's smallest foal.
Einstein, a pinto stallion, weighed just 2.7kg when he was born last Friday in the US, Sky News reports.
His breeder Judy Smith said he was so small when he was born she thought he was dead.
"At first he didn't move very much. We started rubbing him with a towel and he started to move around." she said.
The current record holder for the world's smallest horse, Thumbelina, is 43cm tall.
