Matos, a two-year-old Belgian Malinois that works as an explosive detection dog, picks up a scent and focuses on leading his handler, Stevie Valencia of AMK9, to a buried training target during a demonstration on the Mullet Key Formerly Used Defense Site at Fort DeSoto Park near St. Petersburg, Fla. The specialty dogs are being used as a demonstration technology, to evaluate the potential for using them on other similar sites.
