It really works! Lower Ear Noogies. The Thumper. Lazy Man's Tetherball. Bobbing for Treats. The Hansel and Gretel: for an afternoon of fun, scamper about the house leaving a trail of plain popped popcorn in your wake.

97 Ways to Make a Dog Smile is a gift of pure pleasure for dogs and the owners who love them. Created by Jenny Langbehn, a veterinary nurse who really knows what makes dogs happy, it combines the creative gift of touch--unexpected ways to rub, massage, scratch, tickle, and knead--with imaginative play scenarios that are just loopy enough to ensure that your dog will be amused, whether he's laughing with you or at you. And to heighten the pleasure of both reader and dog, adorable full-color photographs of smiling dogs accompany each entry. Just look at those dogs (you might say), what a tail-wagging, chop-licking, howling good time they're having. And see if your dog doesn't agree.

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.
