About this book
Told in the hilarious voice of a very enthusiastic dog, Jack adores his human "pack," snacks, and chasing anything that moves. When changes come to his household, Jack has to figure out how to be brave, loyal, and helpful—at least as much as a distractible dog can be. Short, lively chapters and lots of doggy misunderstandings make this a laugh-out-loud read. Perfect for animal lovers and fans of funny, fast-paced stories.
Setting: contemporary suburban England
