The Hallo-Wiener by Dav Pilkey

From Dav Pilkey, creator of the New York Times bestselling Dog Man and Captain Underpants series, comes Oscar, a little dog with a big bullying problem.

Oscar is a little dog with a big problem -- he gets more tricks than treats because other dogs tease him all the time. But one brave act on Halloween makes Oscar a Grade-A hero, proving that a little wiener can be a real winner!
