The chief roles of most domestic dogs today are companionship
and affection, so it's easy to overlook the fact that myriad
dogs around the world serve people in additional ways. Not
long after dogs first came to share their lives with humans at
least 12,000 years ago, we discovered that we could train them
to perform certain tasks. The first working dogs may have
helped humans on the hunt or protected livestock from
predators. Over the millennia, we found we could breed them to
our needs, creating dogs perfectly suited to specific
purposes. In this slide show, see ten different dogs at work,
some in age-old jobs, some in jobs less than a century old. To
