Dav Pilkey is just doggone funny. Zuno loves his Big Dog, Little Dog series and Pilkey’s Hallo-wiener is a treat. The long and short of it is that Oscar doesn’t fit in. “Half a dog tall and one-and-a-half dogs long” doesn’t cut the mustard with the gang at obedience school. On Halloween night, Oscar is left behind and must trick or treat alone. When the other dogs are terrorized by a “monster”, Oscar’s unique perspective (down under) and quick thinking earn him a spot with the big dogs when he rescues them from cat-astrophe.
