The 60-second clip captures a very unusual game of fetch.
It begins with an owner presenting a rather small stick to an eager-looking Golden Retriever. The unnamed person then launches the stick down a country lane, and the pooch runs off in pursuit.
Things take a mysterious turn
And that's when things get a bit weird - because when the dog reappears a few moments later with the stick, it appears to have grown to ten times its original size!
So what happened down that mysterious country lane? Does this pooch have some kind of magical power, or is there a different sort of trickery afoot?
Well, given the suspicious-looking cut-scene right in the middle of the video, it looks like the 'magic' happened in the editing room!
But the clip still is putting a big smile on everybody's face - and that's all that really matters right now.
Bred to play fetch
And the pooch clearly had a lot of fun helping his human make the hilarious video. In fact, Golden Retrievers love nothing more than a good game of fetch.
They were first bred to retrieve game and water birds. Hunters prized the Golden Retriever for its 'soft mouth', which is a dog's ability to bring the birds back undamaged.
