Mrs. Dinge, having decided to take a half holiday, provides her squalling half-tone production with the liquid nourishment that gave Milwaukee a place on the map. She then departs for her raid on bargain counters unknown. Another infant, of the bleating bovine variety, likewise deserted by a mother who carries the nourishment with her, endeavors to scrape up an acquaintance with Dinge, Jr., but the miniature chocolate cream drop finds that the calf's tongue produces on his calabash complexion the soft, soothing effect of a coarse-grained emery wheel, and registers his objections to this sort of facial massage at the top of his lungs. The Police Dog hears sounds of distress, and rushes to the rescue. But the calf has it on the pup, and doesn't take any pains to conceal it. The "K-9" sends out a signal of distress. But sleeping is the thing that Office Piffles does beat, and it takes more than a police whistle to wake him. The pup finally gets the cagey sleuth to realize that something's amiss. Piffles manages to rope the cussed calf, who, as soon as he realizes he has Piffles on the string, starts gaily forward at a speed that finally lands the luckless officer down a chimney and onto the furnace griddle. Meanwhile, the Police Dog exercises his talents as a peacemaker, with results that would make the Hague Tribunal green with envy.
