Pig is the world's greediest pug, and on Halloween he is completely out of control, thinking up nasty tricks to play on people who do not give him the treats he thinks he deserves and never sharing with Trevor the sausage dog--until too much chocolate makes him really sick and he finally learns the error of his ways (again).

Pig the self-centered pug, and his friend Trevor, the Dachshund, are at a photo-shoot, and as usual, Pig wants to hog all the costumes and be the star of the show--but the photographer favors Trevor, and Pig needs to learn a lesson about sharing the spotlight.

Charlie is happy to finally get a pet of his own, but trouble brews when King, a dachshund who is devoted to Charlie, makes it clear he does not like anyone else--human or animal.
