Steve Backshall recreates three incredible hunts by some of the world's deadliest dogs, analysing the techniques and tactics of both predator and prey in forensic detail, to reveal why hunts sometime succeed and why they sometimes fail. A pack of grey wolves use canine intelligence to take on a massive antler-armed elk. The rare Ethiopian wolf sniffs out a huge burrowing rodent, the giant mole rat, and African wild dogs match stamina against the pace of the impala.
