This is the first book in this series. In this book the main characters are Dennis and Mellie. They are cousins. This story and finally essay is written by Dennis. He wants a dog. His teacher has told him he must have "criteria" for his essay. As Dennis researches and compares each type of dog he explains which of those characteristics would be best for not only himself, but for his cousin Mellie as well. When he has finished the research he puts it all together into a formal essay. The essay is so good that he and his cousin both get a dog that is best suited to each of them. Dennis gives them each their name. This book takes you step by step through the process. I loved the way that they showed a specific breed, a drawing of it and it's characteristics. Definitely a book I plan to use with my sixth graders. I prefer to make sure they have the basics and this is a great way to do it.

I received a copy to facilitate my review. The opinions expressed here are my own. ( )
