THE relationship between people and dogs is unique. Among domesticated animals, only dogs are capable of performing such a wide variety of roles for humans: herding sheep, sniffing out drugs or explosives and being our beloved companions. It is hard to be precise about when the friendship began, but a reasonable guess is that it has been going strong for more than 20,000 years. In the Chauvet cave in the Ardèche region of France, which contains the earliest known cave paintings, there is a 50-metre trail of footprints made by a boy of about ten alongside those of a large canid that appears to be part-wolf, part-dog. The footprints, which have been dated by soot deposited from the torch the child was carrying, are estimated to be about 26,000 years old.
