Space Dogs

Space Dogs is a 2010 Russian animated adventure comedy film. The film is based on the Soviet space dogs Belka and Strelka, the first animals who survived an orbital space trip, the Korabl-Sputnik 2 flight in August, 1960. In Poland it became the leader of the box-office on its first weekend, although in the United States it grossed poorly, making only $14,408 due to its limited release.
