Petaluma - Lopside is a Barkonaut—a specially trained dog who assists human astronauts on missions in space. He, Champion, Bug, and Daisy are the canine crew aboard the spaceship Laika. When the mission takes a disastrous turn, the dogs suddenly find themselves completely alone on their severely damaged ship. Survival seems impossible. But these dogs are Barkonauts—and Barkonauts always complete their mission.
