Luke is a search and rescue dog with the Corpo de Bombeiros Militar, based in Minas Gerais, Brazil.
On Wednesday, the pup and his colleagues were called in to help track down the toddler, who had wandered away from home while being babysat by an older sibling. An hours-long search by the child's family and neighbors had failed to turn up any clues — but none have a nose like Luke's.
Shortly after arriving on the scene, the dog had found a scent. Over the following 25 minutes, Luke led rescuers through a dense jungle, directly to where the child was standing.
The dramatic final moments of the search were caught on video.
