Dog owners and their pets compete in the final stage of the contest, taking place in the Lake District and hosted by Chris Packham. First, the Red and Yellow teams face a difficult canine intelligence test which involves Lake Windermere and some dog toys, with one pair proving just how far they have come. Then, the remaining competitors must take on a joint triathlon challenge, involving a two-kilometre bike ride, a 100 metre open water swim, and a 1.5 kilometre cross country run. Last in the series.
