This duo might be the best since Fred Astaire and Ginger Rogers. While this act is pretty new to most, there's actually a whole association dedicated to canine choreography. Called the Musical Dog Sport Association (or MDSA), it was founded in 2005 with the goal of bringing canine freestyle dancing to as many people as possible. MDSA defines canine freestyle as a sport that combines training, teamwork, music and movement to orchestrate well-choreographed performances from a dog and human duo. While the dancing itself is fun, the sport's main benefit is increasing harmony and bonding between canine and handler. By celebrating the unique characteristics of each dog through choreography, owners can learn more about who their pups are.
