Ruff Day: Charlie's Rules #2 (Paperback)

Is a puppy more important than a science project?

Charlie knows how to make his group science project an organized success. But his best friend, Amy, would rather it be fun and gross. And their other partner, Jenna, is too worried about why her puppy keeps attacking her mom to think about their project at all. Charlie and Amy want to help Jenna, but what they don't realize is that the puppy isn't trying to hurt anyone: he's trying to save someone! Can the kids figure out what he's trying to tell them before it's too late and will Charlie ever get their project back on track?
