Marking off of the gun barrel then begins in the living room. "A hot dog stuck in my gun barrel gets the dog's attention when I say, 'Watch it,' but with tight heel control I can stop him from jumping out and snatching it," says Don. "I slowly, carefully lead him around in a circle at first, then gradually expand the course. When raising the muzzle gets instant attention, we move to the blind, where bird launchers are stationed on all four sides. Getting to retrieve soon has the dog watching the sky wherever the gun points."
