We now recognise over 400 breeds of dog, each with its own fascinating, often mysterious history - in fact we've bred dogs for just about every job you can imagine; and as our modern world changes, dogs have adapted alongside us. The unparalleled cooperation between us and our dogs has led to some of the most remarkable partnerships on earth, from sheepdogs to guide dogs; and dogs bring everything from their super senses to obvious enthusiasm to all their various roles in our modern world.
