Martin Clunes narrates this heart-warming and revealing film, bringing you dogs as you've never seen them before. Using state-of-the-art technology - including some amazing slow motion footage - we find out how our favourite animal sees, smells and experiences its very different world. Follow the life of a cute puppy from birth through to its own pregnancy, and hear personal accounts of dogs that have saved lives, rebuilt marriages and detected diseases. Part natural history, part science and part pure celebration of man's best friend, this programme highlights just how extraordinary dogs truly are.
