Thanks sarx. In this video, they say a special dog has been brought in. It looks like a bird dog of sorts. Do you know what the pup might be trained to search?

Not sarx-
But it might be trained for HRD work, or it might be trained for narcotic detection, arson detection, or bomb detection. Dogs trained in those disciplines behave the way you see on the video when working. It may also be cross trained.
