Mark Muir and Rocket, Freestyle

Mark Muir and his 8-year-old Border Collie, Rocket, have earned a number of titles since Rocket caught his first disc in 2005, including a World Championship and five National Championships. The pair competed in two events at the Purina Incredible Dog Challenge on Oct. 1: The Freestyle Flying Disc and a brand new event, Speed and Catch, where the pair took the top spot.

Muir, a fire captain in Atlanta, always had a positive attitude toward training and competing with his dogs, but after suffering a stroke last year, he renewed his commitment to enjoying every minute he spends with his Georgia Irish Disc Dogs, and when he and Rocket took the field, that attitude showed. But he puts just as much emphasis on keeping his dogs safe and injury free.

In this original video, he offers some tips on how to get started in disc dog sports and how he trains his world champion canines while preventing any injuries.
