The dog on the left pauses behind a rock outcropping, but the one on the right continues its beeline toward us. I raise my rifle and prepare for a shot. I can hear the dog’s legs brushing against the dried grasses as it closes the distance. Nearly 100 yards out, it stops and stares, sensing something amiss. Valpiani tugs on a stretch of parachute cord tied to a small bush, shaking its branches to create the illusion of struggling prey. But the coyote isn’t buying it, and if it doesn’t see something more convincing soon, it’s going to bolt. I center the crosshairs over the dog’s chest and squeeze the trigger. The dog drops to the desert floor—and now the con is over. The coyote by the outcropping races back toward the fence, but in an amazing demonstration of poise and marksmanship, Valpiani aims, shoots, and watches the coyote tumble head over heels, 50 yards from the private-property boundary.
