Kosmo, the king of troublesome terriers, takes trouble to a whole new level! He’s a one-of-a-kind, corn-on-the-cob nibbling, ice cream licking, always-into-mischief dog. Kosmo’s Christmas Delivery is told from the point-of-view of an older, but not necessarily wiser dog, Kramer, who laments the acquisition of Kosmo by his family, especially his girl, Emily Jean. When the inquisitive Kosmo jumps on board the Yellow Package delivery truck a few days before Christmas, Kramer, secretly wishes the pup will be lost forever. He reluctantly agrees to help Emily Jean search the snowy streets of their small town for Kosmo. Through a series of unusual events, the missing terrier finally comes home, but not a moment before his older sibling realizes how much he cares about his young friend.
