Here’s an example. I was working with my dog Manny on the NAVHDA Utility-level “duck search.” Ultimately, Manny would be required to swim and wade a brushy pond for ten minutes, trying to find a wing-shackled duck that is trying hard not to be found. The most valuable skill for this test requires him to use his nose to suss out faint duck scent lingering in the air, on the water, and and in the vegetation. It’s easy for Manny entering a small pond downwind of the duck – that’s his comfort zone right now. But every once in a while, I’ll put him on the upwind side of the pond so he has to expand his search before hitting duck scent. It’s a stretch, literally, but he’s proved up for the challenge.
