Try In a Nutshell, the classic sleight-of-hand game, by hiding a treat under one of three plastic cups. The Lawrence Welk--dogs love to chase soap bubbles even more than toddlers do. Get fit while playing. Or use Subliminal Advertising, which works by sneaking a favorite word like cookie into an otherwise boring rant. You'll be surprised by how closely your dog pays attention to what you say, and how broad the smile will be when he hears that special word. Just be sure to have said cookie on hand.
