This mini horse has barely seen the world - but he already likes what he sees.

A recent video shows the teeniest, tiniest miniature horse - only 3 days old - chasing after one of his carers, whom he's apparently decided is his new best friend. And it might just be the cutest thing in the history of the universe.

Wherever his new friend runs, the tiny horse follows. And when he finally catches him and get some well-deserved pets, he wags his little horse tail just like a puppy.
