The cattle dog-mix races across the turf, his claws digging into the ground, pushing hard into his next stride, building momentum, faster, faster, faster. With a final turbo blast powered by his rear legs, he pushes off the ground and vaults into the air, seemingly weightless as he stretches his neck into the sky. A sudden twist of shoulders propels his torso and hips 180 degrees as he changes direction midair and snatches the prize from the air - a simple, round plastic disc. Eyes alight with the thrill of the chase and the kill (catch), he lands nimbly and races back to his handler. Can we do it again? Can we, can we? Yeah, we can. This is the sport of disc dog. It's been around since Frisbees became popular in the early 1970s and the players' dogs chased the players' errant tosses. When a bad toss resulted in a disc rolling on its side, that was fine by Fido.
