this was my favorite book so far. not only has Petey improved as a character a lot, become more considerate, and more of a dad to li'l Petey, but the book is more about li'l Petey than anything! I love his character, and his story is such a strong message to be aimed towards kids. originally, this book series was about dog man, just fighting, but now it's all about li'l Petey trying to teach his father to love, and change. Petey was never prepared for parenthood, like most other parents, and he has already changed so much! to be honest, I just really love this book!
