Gr 1–3—While practicing for the upcoming agility show, Cody notices a lump on his dog's belly, which turns out to be cancer. The treatment is similar to what a human endures, and Cody is filled with worry for his pet. Champ is able to participate in the show, but it is Cody who has trouble when he trips and hurts his ankle. Now it's Champ's turn to take care of Cody, and she proves she is a real champion. Children will have empathy for both characters. The book includes extensive curriculum-related back matter that will assist teachers and parents as they share this title with kids who have similar concerns, and the publisher's website has additional resources. A sincere, caring story told with a straightforward, honest approach.—Helen Foster James, University of California at San Diego
