Dog Man Unleashed is the second book in the Dog Man series. It is written by the same author as Captain Underpants so if you like those books, you will LOVE this book. It is about a police man with the head and brain of a dog. There is a short summary of how that happened in the beginning of the book. But if you want to follow the entire series you should also read the first Dog Man book. In the book there are mysterious things happening and it is up to Dog Man to figure it out and stop the crime. This book was fun to read because of the entertaining story and vivid pictures. It also has instructions of how to draw the characters in the back of the book and a bonus comic. I personally would recommend this book for kids in grades 2-5.
