Sassy and Waldo are good dogs. They will do anything for their boy, Stewart. That includes putting on a trench coat and pretending to be a new student named Salty in his class just to make sure he is happy. But this month Stewart's class is going to put on a play. PLAY! There's nothing that dogs love more than to play. Well, except maybe eating hamburgers, napping, and chasing squirrels. But they're all equal. It's a four-way tie! Sassy and Waldo are in for a big surprise when they learn what a school play really is!
