Dogs and humans: in the last 200 years no inter-species relationship has developed so fast nor come so far. Dogs accompany us in every walk of life, usually three times a day. How and why did this relationship begin? How has it changed over the centuries? And who's getting the upper hand? This title investigates this unique bond by revisiting some of the most important milestones in our shared journey. It begins with the earliest visual evidence on ancient rock art, and ends at the laboratory that sequenced the first dog genome.
