Best-selling author Katherine Applegate returns for another hilarious life lesson with the antics of wellmeaning Roscoe Riley. It seems everyone is winning trophies lately-except Roscoe. A dog trick contest could turn things around, but Roscoe's goofy dog can't learn any neat tricks. So he decides to trade the sweater his grandmother knitted him to borrow his neighbor's genius dog. Roscoe didn't much like the sweater before, but now that it's gone, he's starting to wonder if he made the right decision.
