When Ivan's parents find good jobs and the family moves from their small, crowded apartment to a new, spacious one, they realize they have left something precious behind.
Times are hard for Mommy, Daddy, and Ivan. They live in a tiny apartment and only have room for an imaginary dog, Ronny, who behaves badly--especially at night. They love him, anyway. One day they are able to move to a larger apartment and have room for The Real Ronny! A real dog! He’s wonderful, of course. And they love him. But sometimes you can’t help missing the things you left behind.
