Some sled dogs will put just enough pressure into the harness to appear to be working while they’re actually taking a break. “Honest dogs” throw their full weight into the straps no matter how tired they are or how much further there is to go. These dogs take the lead positions in the harnesses so that they can set the pace for the rest of the team.
Much of SOF selection is separating the honest dogs from the dogs who are going home.
