Extraordinary Animals: The SOS Dog Squad

Documentary series profiling remarkable animals from across the globe. This edition focuses on some truly Herculean hounds - three working dogs who are so adept at their jobs that they leave their human counterparts in the dust. There is Saxon, the pooch who can sniff out suspicious circumstances in burnt buildings; Bilbo, the craggy canine who patrols the dangerous shores of Cornwall; and Orson, the awesome avalanche rescue dog.
