Korby Kost owns a feedlot in Carrington, North Dakota.

"He's a Blue Heeler, and we call him the wheeler heeler," said Kost.

Patton's custom-made mobility cart features a two-wheeled herding harness, allowing him to run free on the farm.

But Patton doesn't just herd cattle. Kost says his two-legged friend also loves wrestling with the neighbor's dog.
