Dominic has decided it is time for a change. So he packs up his hats and his piccolo, and sets off into the unknown. But no sooner does he feel the air on his snout and the grass beneath his paws, than disaster strikes: he encounters the dreaded Doomsday Gang. But Dominic is not one to complain – and nor is he one to lose a fight. As legend of his victory over the villains spreads, more and more creatures turn to him for help: a 158-year-old turtle, a heartbroken wild boar, and a family of grateful geese all encounter Dominic’s heroism and generosity. But his trials are far from over: the Doomsday Gang is alive and kicking, and how can one young dog face a mob of hooligans alone?
