The Monroes and their pets are camping at Boggy Lake on a fun outdoor adventure - at least it is for the humans. The pets are not so sure. The two guys in the tent next door look distinctly unwholesome, as does their drooling bulldog, Dawg. Chester's antennae for unnatural goings-on are on red alert - Dawg has a weird look about him, and a rather aggressive manner. But when he invites Harold, Howie and Chester to take a walk in the woods with him, nobody likes to say no. Hours later, they realise they're lost. Has Dawg deliberately led them astray? And if so, what does he plan to do with them? Will they ever get out of the woods alive . . ?
