To lose 30 pounds, Patti Lawson worked like a dog. And now, she's written a book to prove it. Lawson is author of "The Dog Diet," a memoir stuffed with anecdotes about how her real-life pooch helped her lose the one around her tummy — and regain self-confidence, hope and a bit of wit in the process. The attorney-turned-writer's narrative was named "Dog Humor Book of the Year" by the Dog Writers Association of America in February.
