'3 Mallory vs. Max, Paperback

Spunky, eight-year-old Mallory McDonald is very unhappy when her parents decide to get her older brother Max a dog. Why would her parents agree to such a thing? Dogs are smelly and bark and chew on things. Plus, they already have a perfectly good cat, Cheeseburger. When they finally get the puppy, it's worse than Mallory imagined. Everyone loves Champ and he and Max are getting all of the attention. Poor Mallory--now everyone's mad at her. What should she do?
