Shadows have always held a kind of magic for humans. We use them in art, to send messages, and even to guess when Spring might show up. Around the world, parents make shadow puppets to keep kids entertained while waiting at the doctor’s office or in line somewhere. But humans aren’t the only ones who notice shadows. When one playful Labrador spotted his shadow for the first time, his reaction was absolutely priceless.
Animals and the Mystery of Moving Shapes

Animals rely on their vision for many things—especially when it comes to play or survival. Cats and dogs love to chase tiny lights and moving objects, like a laser pointer or a dangling toy. Every February, people gather to see what a groundhog named Puxatawney Phil will do. If he sees his shadow and dives back into his burrow, that means six more weeks of winter. But if he doesn’t see it, we can supposedly expect an early Spring. Whether or not Phil’s shadow actually predicts the weather doesn’t stop people from enjoying the tradition.

Meet Charlie: A Labrador With a Hilarious Reaction

Different animals react in their own ways to shadows. Take Charlie, for example. He’s a Labrador who loves attention and often spends time with a woman named Niki Kivett Gilbert. One day, while visiting her, Charlie noticed his own shadow—and what happened next was pure comedy.
Charlie’s behavior fits perfectly with the word “derpy”—which basically means silly or goofy. As soon as he spotted the dark figure moving with him, he got super confused. Thinking it was some sort of creature, he tried to bite it and kept nudging his nose into the wall, completely baffled by what he was seeing.
Shadows Can Be Fun… or Frightening

As Charlie’s human looked on, laughing at the scene, the pup took things seriously. He leapt at his shadow like it was an enemy. He even showed his teeth and growled, trying to scare off what he didn’t realize was just a dark version of himself.
We might take the time to explain what a shadow is to a curious toddler, but try doing that with a dog! Most people probably wouldn’t even try. Instead, they’d just let the dog keep going—or offer a tasty treat to break the confusion. Either way, Charlie’s silly moment is a reminder that even something as simple as a shadow can turn into a whole lot of fun.
