Before every dog agility event, the human handlers walk the course as a group – without the dogs – wandering slowly round the ring with one hand or the other outstretched. It’s an eerie thing to watch, like a crowd of bleary eyed tourists wearily progressing through an airport.
But it’s important: the dogs don’t get to try the course beforehand, so their handlers have to formulate a strategy to guide their pets from jump to tunnel to seesaw in the correct order.
