Book excerpt: Britain's answer to Marley and Me-the hilarious and heartwarming international bestseller about learning to live with a troublesome dog. Like many first-time pet owners, London-based novelist Stephen Foster was upbeat as he began his search for a puppy to adopt. How hard can it be to take care of a dog, he thought-read a guidebook or two, buy a few supplies, and get on with it. But all the books and supplies in the world couldn't have prepared him for life with Ollie, a willful and moody adopted dog who quickly demonstrated his displeasure at the notion of being told what to do. Walking Ollie tells the funny and charming story of how a growling, skittish man and his equally growling, skittish dog broke each other in, came to see eye to eye, and decided to become best friends.
