If Opal hadn't kept Winn-Dixie then story would be so boring. If she had left Dixie at the store with the workers chasing after Dixie then, I would think they would treat Dixie bad and they would send him to the pound and they would treat Winn-Dixie badly (what I think). Also I think Opal would be lonely like she kind of was before Winn-Dixie. I'm would recommend this book to 4th and 5th graders because it's like very easy to read but a great book to enjoy. This book is amazing!!
