Martin Clunes is happy to admit that with Mary, it was love at first sight; her soft, brown eyes, her perfect figure and that unstoppable wagging tail. As cocker spaniels go, she was perfect. It is a love that has taken them through puppy classes to the local dog show, a move to the country and even visits from a dog psychologist, and has often caused Martin to wonder: Where the hell did you come from? To find a satisfying answer to that question, Martin embarked on a worldwide quest to look into the history of dogs, and link the pampered pets of today with their wild ancestors, painted dogs in Tanzania, dingoes in Australia and wolves in Yellowstone National Park, USA. He also explores how humans have shaped the dog breeds of today, visiting the Beverly Hills Mutt Club and meeting working dogs in several countries; police dogs, hunting hounds and sled dogs. Accompanied by his stunning photography, Martins account of his discoveries, told with his trademark warmth and humour, is compelling and full of surprises. One thing is certain: at the end of this fascinating journey, Martin will never look at his own dogs in the same way again.
