The Dog Man series by Dav Pilkey, the creator of Captain Underpants, is a graphic novel series that explores positive themes like kindness, empathy, and persistence. The story follows Dog Man, a heroic hound with a dog's head and a human body, who was born from a life-saving surgery after a police dog and his partner were injured. Dog Man has a nose for justice and can muzzle miscreants, but he also leaves a trail of slobber.
