Guinness the border collie loves the program. Flip on the monitor, and she can sit for hours watching the colorful images flitting across the screen -- 
like a teenager in front of a Playstation. As soon as the images change she presses the touch screen with her nose. If she selects the correct one of two photos, a piece of dry dog food automatically drops down to her feet. If she selects the wrong one, the screen turns red for a moment, and then the exercise continues. You can read more of the story here.
