"He'll scratch with one [paw] and stick his nose in the snow," Gray said in the video. If the scent gets stronger, Mason will use both paws and dig faster. "You'll see his tail's in almost work mode, where it's not wagging, kinda stiff," he said.
Mason's only 2 years old, but he's already learned a lot about the game of hide-and-seek. If he continues on the training schedule that Gray and the other members of Copper's Patrol have created for him, he'll learn even more and continue to rescue for years to come.
