A Dog's Life examines how our canine companions perceive the world - from the moment they take their first morning walk to the time they curl up at our feet to go to sleep. We accompany Daisy, a Jack Russell terrier, through an average day and on the way discover that, while dogs are not miniature humans, they are amazingly well-adapted to life with us. Ingenious experiments and meticulous observation reveal that the problems dogs solve best are those that involve interacting with humans. They are social creatures highly adapted to understanding even our subtlest gestures. Dogs fit so well into human society that we have bred them into the most varied species in the world. But every one of them, from the giant Newfoundland to the tiniest Chihuahua, is descended from that most widely feared predator - the wolf. But unlike the wolf, dogs and humans developed a deep mutual sympathy, which after thousands of years resulted in dogs not only preferring human company to that of other dogs, but also provided them with an uncanny ability to understand us.
