Where can I watch Space Dogs in United States?

Laika, a stray dog, was the first living being to be sent into space and thus to a certain death. A legend says that she returned to Earth as a ghost and still roams the streets of Moscow alongside her free-drifting descendants. While shooting this film, the directors little by little realised that they knew the street dogs only as part of our human world; they have never looked at humans as a part of the dogs’ world.
