Ladito, Campeona, Bicho, and Margarita are Barkonauts, dogs especially trained to help human astronauts on missions in space. He and the crew aboard the spaceship Laika are en route to set up an outpost on a distant planet. When the mission takes a disastrous turn, the Barkonauts on board suddenly find themselves completely alone on their severely damaged ship. Survival seems impossible. But these dogs are Barkonauts--and Barkonauts always complete their mission.
