He was the best of dogs... He was the worst of dogs... It was the age of invention... It was the season of surprise... It was the eve of supa sadness... It was the dawn of hope... Dog Man, the newest hero from the creator of Captain Underpants, hasn't always been a paws-itive addition to the police force. While he can muzzle miscreants, he tends to leave a slick of slobber in his wake! This time, Petey the cat's dragged in a tiny bit of trouble -- a double in the form of a super-cute kitten. Dog Man will have to work twice as hard to bust these furballs and remain top dog!

The eighth book in Dav Pilkey's mega-bestselling Captain Underpants series. Now with super-cool foil covers! Shiny! Fun! When we last saw George and Harold, they were about to take their pet pterodactyl Crackers back to the Cretaceous period. But things didn't work out quite as they had hoped. They've entered an absurd alternate reality where teachers are nice, kids are allowed to read banned books, and the cafeteria food doesn't smell like dirty diapers. Even worse, they've discovered alternate versions of themselves--Evil George and Evil Harold--who plan to unleash some preposterous plans on Piqua, Ohio. Now it's up to George and Harold to defeat the evil twins and THEIR superhero, Captain Blunderpants!
