This book works on so many levels for readers of any age. I think Planet of the Dogs would be a great book to read out loud to younger children, older children will be challenged by the strong use of more complex words and adults will just plain love it. The story is a timeless classic about how goodness triumphs over evil and well, you know, dogs are the ultimate good in my book. I think my favorite part of the whole book is when Lucy (the ruler of Dog Planet), decries that any child who wants a dog will get one! Planet of the Dogs shows just how important dogs can be in anyone's life.
