All Shapes & Sizes

From huge dogs to tiny dogs, working dogs to lap dogs, dreadlocked dogs to hairless dogs - no other mammal species demonstrates as much diversity in size and appearance as the domestic dog, and in the first episode of The Wonder of Dogs, hosts Kate Humble, Steve Leonard and a team of canine experts explore why - and how - dogs come in so many shapes and sizes. Kate traces the remarkable evolution of the domesticated dog from its ancient ancestor the wolf through thousands of years as our working companion, to the development of the dog breeds we know today. Steve meets one of the hairiest dog breeds of all, and discovers how the dreadlocked coat of this livestock guardian acted as its armor. Historian Ruth Goodman uncovers the surprising origins of the Poodle's famous haircut, and visits the ancestral home of the Golden Retriever.
