How Dogs Conquered the World

One billion dogs live on Earth today. However, tens of thousands of years ago, before man shaped them, dogs did not exist in the wild. Dogs bald or bearded, spotted or furry, large size or miniature, delicate or all terrain. Dogs have invaded our planet. They've become so much a part of our daily lives that they're practically indispensable. They can even communicate with us. How did poodles, greyhounds, or chihuahuas conquer the world? Zoo-archeologists, biologists, ethologists and geneticists are leading the investigation. For one thing is certain, the dog is still far from revealing all its secrets.
