Everyone knows that owners and their dogs belong together in a unique way. Polly belongs to Molly, Eric belongs to Derek, Berry belongs to Terry. But poor Mr. Scruff, alone in the rescue shelter, doesn't belong to anyone. Then a boy named Jim walks in, and they seem to get along. Jim and Mr. Scruff don't look anything alike, and their names certainly don't rhyme, but they may end up belonging to each other just the same.
