Friday, 7.30pm, Nat Geo Wild In the heartland of Indiana, there’s a training facility unlike any other. It’s one of the largest police and military dog training kennels in the world. With grammar as dodgy as his haircut, Kenny, one of the five bikers who run this place, says: ‘‘ They’re not pets, it’s a f . . kin’ tool.’’ This made me unsure about just who the ‘‘ f . . kin’ tool’’ was. Oh, and there are so many secrets, including blurring the faces of special forces personnel. ‘‘ Our dogs got the opportunity to take down famous terrorists — names you’ve heard of that we just can’t talk about,’’ says boss guy Danny. Oh really? Why not? It’s not as if the terrorists’ lawyers are going to sue. Look, the dogs are great, and they try so hard to work out what they are being taught to do in tough circumstances it almost makes you cry. But there’s just too much filler, such as the scene in which team members learn to abseil. ‘‘ You look like the prize bull at the county fair.’’ Quite.
