Dog on It Book: Chet might have flunked out of police school ("I'd been the best leaper in K-9 class, which had led to all the trouble in a way I couldn't remember exactly, although blood was involved"), but he's a detective through and through. In Dog On It, Chet and Bernie investigate the disappearance of a teenaged girl who may or may not have been kidnapped, but who has definitely gotten mixed up with some very unsavory characters.
