From the bestselling, award-winning author-illustrator team of Doreen Cronin and Kevin Cornell comes the first book in a heavily illustrated, hilarious chapter book series about the adventures of a dog detective. Perfect for fans of Sara Pennypacker's Clementine series and Jarrett J. Krosoczka's Lunch Lady series.

J.J. Tully is a former search-and-rescue dog who is trying to enjoy his retirement after years of performing daring missions saving lives. So he's not terribly impressed when two chicks named Dirt and Sugar (who look like popcorn on legs) and their chicken mom show up demanding his help to find their missing siblings. Driven by the promise of a cheeseburger, J.J. begins to track down clues. Is Vince the Funnel hiding something? Are there dark forces at work—or is J.J. not smelling the evidence that's right in front of him?
