Dogs sniff out drugs, bugs, and land mines. They aid search-and-rescue missions, assist hunters, and help herd livestock. In this slide show, see 10 different dogs at work, some in jobs less than a century old, and some in jobs that may have been performed by the first domesticated dogs some 12,000 years ago.

Working dogs use their canine instincts and powerful sense of smell to perform a wide variety of jobs.
