Who knew chasing a rat in the middle of a Christmas pageant could cause so much trouble? Certainly not Doodle, the obedience-impaired labradoodle who works for "the boss,” Josh Hunter of Hunter Bed Bug Detection, nor Molly, the boss's ten-year-old daughter. But then Doodle is the first to admit he doesn't quite get Christmas. Doodle's antics during the pageant draw the attention of a popular video blogger, who asks to do a feature on his sniffer dog skills. But when the blog airs, pretty much the opposite of what Molly and the boss expected, the boss's phone rings off the hook with distraught customers who think Doodle’s bed bug “finds” can’t be trusted. Molly, searching for a way to set things right, befriends the blogger's son, a boy alienated from his mother who wants only to go live with his father. Throw in a handful of threatening letters, some lost dogs, and a devastating fire, and Molly and Doodle have their hands—well, in Doodle's case, his paws—full finding out just who's been naughty and who's been nice.
