Squirrel and Arrow - dogs that returned to earth after flying into space, are known to everyone.  These brave dogs did not belong to any breed. 

 Few people know that they were doubles of the other two dogs - Seagulls and Chanterelles.  These dogs died during the unsuccessful launch of the ship.  Many do not know about the existence of another four-legged hero who helped to master space - Laika dogs.

  It was launched into space the very first.  The design of the device did not provide for the animal to return to Earth ... Laika died about seven hours after the launch of the ship from overheating.

  These dogs opened the way to space for us ... Laika, Seagull and Chanter gave their lives to make a breakthrough, the value of which is difficult to not appreciate.
