Charlie and Itchy's attempts to reclaim their goods fail but they discover Carface is working for Annabelle's evil cousin, Belladonna, who plots to use a massive dog whistle to hypnotize every dog in the city into stealing the masters' Christmas presents, causing them to be thrown out of their houses and abandoned by their owners, much in the same way Carface used to be when he was a puppy.

Charlie plots to scare "the Dickens" out of him and asks Annabelle for some aid, resulting in them being transformed into characters from A Christmas Carol.

At Itchy's insistence, Carface reveals that he was a happy puppy but his owner blamed him for making a mess of Christmas decorations, which gets him thrown out.

Betrayed, Belladonna flies into a frenzied rage and is about to kill Carface and Killer when she is frozen solid by a massive amount of snow caused by Annabelle.
