Russian scientists chose dogs as the most suitable animal to send into space because they felt that dogs would be able to endure the long periods of inactivity better than other animals. When they first started sending dogs into space, they took small unwanted dogs from the streets of Moscow and sent them to research centres where they were trained to stand still for long periods and also to wear pressurized suits and helmets.
