This viral video of an adorable tiny horse who won’t stop chasing his owner is turning us into a giant puddle of emotions.

The best part? This sweet baby is only three days old, so he’s most likely one of the tiniest little horses you’ve ever seen. He’s already full of boundless energy — instead of staying by his mother’s side, he’s striving to take on the world.

Watch as the sweet horse runs, moving his short legs as fast as he possibly can. When the little one catches up to his handler, he even wags his tail like a puppy. The endless love he already has for his human is the most heartwarming thing we’ve seen all week.
