21+mph+keju

You stop throwing the disc entirely. Instead, you use a whip-and-dummy system. The handler cracks a 6-foot lunge whip with a fleece tug at the end, moving at 21+ mph horizontally. The dog chases and catches the tug while a radar gun (like a Bushnell Velocity) records the run. Only when the dog naturally executes the "Keju Curl" chasing the tug do you put the actual disc back in your hand. Why the 21+ mph Keju Matters in Competition In the 2024 UpDog International Championships, a statistical anomaly occurred. Of the 450 Freestyle runs, exactly zero dogs scored in the top 10 without at least two 21+ mph keju maneuvers per round.

In response, the International Disc Dog Handlers Association (IDDHA) introduced a 21+ mph Keju waiver in 2025. Any team attempting a speed-checked catch over 21 mph in the "Speed Round" must sign a digital liability waiver and post a pre-run vet check. 21+mph+keju

Coined initially on the Dogster Pro forums in 2018, the term "Keju" refers specifically to the complex, mid-air rotational maneuver a dog performs to catch a disc at extreme velocities. At speeds below 18 mph, a dog uses a standard "leap and snap." But at , physics forces the dog to execute the dreaded "Keju Curl"—a 180-degree spinal rotation combined with a rear-kick tuck that keeps the tail from striking the ground.

For those who achieve it, the 21+ mph keju becomes an addiction. You will chase that speed every sunset at the park, your radar gun in one hand and a scuffed Jawz disc in the other. Your neighbors will think you are crazy. Your dog will think you are a god. The dog chases and catches the tug while
