Competing canines on primetime TV invoke memories of the heyday of A Dog's Show in this TVNZ series. Tux was presented and produced by dog lover Mark Leishman, with his faithful golden Labrador companion Dexter (until the latter's death in 2000). Jim Mora provides a genial and pun-filled commentary as obedience tests and obstacle courses challenge the teams of dogs, and exasperate (and occasionally delight) their owners. Titbits come in the form of dog lore and trivia, advice from pet psychologists and canine funniest home videos.
Dogs of all shapes and sizes — from huskies and ridgebacks to Alaskan malamutes and King Charles spaniels — compete in this episode of TVNZ's canine challenge. Encouraged by their unfailingly devoted owners, they display varying degrees of ability and interest in an obstacle course, sprints, fetching and scent tests. Away from the cauldron of competition, presenter Mark Leishman's golden Labrador Dexter — the real star of the series — has his portrait painted and there's home video of the lengths, and heights, one dog will go to for a drink of water.
