Everything you need to understand or teach Dog Man by Dav Pilkey.
Dav Pilkey's two graphic novels, Dog Man and Dog Man Unleashed, feature a police officer with the head of a dog and the body of a man. The strange combination of physical characteristics are the result of putting together the body parts of a man and dog after a bomb explosion. The character faces all sorts of evil, from a menacing mayor to a paper cat that comes to life. Dog Man always saves the day, often by using his wits. Pilkey writes the novels as if two young boys, George and Harold, are the authors. The themes of the graphic novels include good vs evil, Petey's selfishness, and Dog Man's relationship with the Chief.
