The Secret Life of Dogs

The Dog - Man's best friend and companion for ten thousand years. But how much do we really know about our four-legged friends and where they came from? Dogs are the most diverse species of mammal on the planet - there are an incredible 340 breeds each with their own distinctive appearance, character and super-power.

Great Danes are an incredible 20 times bigger than a Chihuahua; Dobermans naturally guard us, whilst a Poodle will comfort. But why are they so different? Where in the wild did they originate? And how much do we really know about them? In this series we discover that all 340 breeds fall into three very characterful and distinctive dog tribes: the guardians, the workers, and the companions.
