I liked the book, "It's a Doggy Dog World (Crimebiters #2) by Tommy Greenwald because it has a lot of humor and mystery. I also liked the book because it's in Jimmy's point of view. The characters in this book are Jimmy, Irwin, Daisy, Baxter, Dad, Mom, and Abby. In the beginning of the book, Jimmy and the Crimebiters hold a meeting where they report if they have seen a crime around Quietville. I liked this part because they were talking about what crimes they have seen so they can stop them. In the middle of the book, Abby has been taken to an obedience class because she chewed up Mom's shoes. I liked this part because this means that Abby will start behaving better and be a good dog. In the end of the book, they solve a crime that would've hurt many other people if it wasn't stopped. I liked this part of the book because they solved a crime that would've injured people.
