In 2012, a duo named Ashleigh and Pudsey stormed onto the stage of the U.K.'s hit reality show, "Britain's Got Talent," winning the title for their dynamic dance routine. The pair won the audience's hearts and the judges' scores for their choreography, costumes, perfectly timed dance moves and synchronized tricks. Ashleigh certainly holds up her end of the duo, but the real star of the pair is Pudsey. And unlike most dance partners, Pudsey is a dog. And their dance routine, officially called canine freestyle dancing, is a big thing.

You can see Ashleigh and Pudsey dancing to "Gangnam Style" at the U.K.'s National Television Awards in the video above, and below is a look at Ashleigh and Pudsey's winning performance for "Britain's Got Talent."

As cute as they are, Ashleigh and Pudsey certainly didn't invent freestyle dog dancing. The movement traces its history back to the late '80s when demos started popping up around the world. By 2000, various organizations were hosting competitions with specialized divisions based on the age and talents of the handlers and dogs.

Here's a video of the top 10 competitors at a recent competition. (Yes, we know it's eight minutes long, but just take a look and skip around; you'll be glad you did.)

As you can see, the movement has evolved into something that's one part obedience training, one part dance, and one part theatrics.

You can get something as magical as this freestyle routine set to "The Last Unicorn":

Or cute but slightly creepy, like this freestyle dog dance number set to "You're The One That I Want" from "Grease":

Either way, the dancing's not going away anytime soon. Now that you know about it, you can look forward to many more hours watching the handlers and their whip-smart pups dance the night away.
