Gaston works the hardest at his lessons on how to be a proper pooch. He sips - never slobbers! He yips - never yaps! And he walks with grace - never races! Gaston fits right in with his poodle sisters.But a chance encounter with a bulldog family in the park-Rocky, Ricky, Bruno, and Antoinette-reveals there's been a mix-up, and so Gaston and Antoinette switch places. The new families look right...but they don't feel right. Can these puppies follow their noses-and their hearts-to find where they belong?
