Set a plate with a cookie on it, off in the distance. (Point B).
Start at Point A with the dog, and with a broad hand motion: Point to the plate and say, “Go out.”
Your dog will run in the direction you point, to the plate.
Gradually move the plate farther away.
Then find a shallow hill, and place the plate on top of the hill. Point, and do the same things as described above.
After you’ve been doing this consistently for several days, begin placing the plate “behind the horizon,” but let the dog see you do it.
Next, do it again (after a few successful days) but don’t let the dog see you put the plate out.
Repeat in a variety of situations, always using the same command.
