For fans of Ben Fogle and dog lovers everywhere, this is Kate Humble's heartwarming exploration of the relationship between man and his best friend.

There is one animal that is familiar to all of us, whoever we are, wherever we live. Even if we've never had direct contact with one, we will have seen one, or at the very least, heard one. For those of us who live in the western world it is more than likely that one sleeps in our house, possibly even on our bed. I'm talking of course, of the dog. Yet, this animal, which lives alongside five hundred million of us all over the world - as an invaluable partner and a trusted confidant - presents us with one great unsolved mystery: how did this relationship - the most complex and enduring of any between human and animal - start in the first place?

Kate Humble is a life-long animal lover. Now living on an idyllic farm in Wales, she has achieved her dream of surrounding herself with as many varieties as possible. But, as with many Brits, the dog has always held a special place in her heart. Here, she uses her journey with her sheepdog puppy Teg to frame her examination of this very special relationship. Written with warmth and love, and packed full of stories about rescue dogs, guide dogs, service dogs and medical dogs, this is a must-read for anyone with a four-legged friend.
