On a dare from her best friend, nine-year-old Tawny gags down a piece of dog kibble. Suddenly she can hear and talk to dogs, including her own dog, an enormous and demanding Great Dane named Dinky. Dinky explains to Tawny that his fondest wish is to be a tiny lap dog and Tawny promises to help him become one. From helicopters to the five o’clock news, Tawny soon finds out what it means to make a promise to a friend. Along the way, her parents can’t help but question her sanity and her best friend Jenny turns into her worst enemy. If Tawny can just keep her own thoughts straight, maybe she can make things right in her family, get her best friend back, and decide for herself how she will handle having such a special gift.
