I think this book is interesting because it keeps a secret from the reader and reveals it at the end. My favorite character is Marvin. I like Marvin because he is just a normal kid like me. I liked this book because I like dogs and it has a lot of things that have to do with dogs. My favorite part of the book was when Marvin calls the vet because he lost Waldo.
I think people in second and third grade should read this book. This book is not too long or too short, perfect when you forget your longer book at home. I give this book 4 1/2 stars out of 5 because it has really descriptive writing.
