When Tishka went into space, the world started to dream again. If people were sad, or scared, or alone, they would look up at the sky and see Tishka, and be reminded that everything is possible. And following in his footsteps, people went to space too. He had never dreamed of going to space, but fate intervened. And once he got there, he could not go back. He left a puppy on Earth, his beloved Sashenka. Now, Tishka circles the Moon. He's looking out the porthole, thinking, "Everything would have been so much easier if I had been someone else; if I could be an Earth dog." But what could Tishka do? Tishka is not an Earth dog; Tishka is a space dog.
