For anyone who loves a dog--and anyone who loves a laugh, comes this sensitive (and silly!) story about growing up and mending fences. An enduring message of friends, community, and the joy of pets. Ask anyone who has a dog and they’ll tell you that their dog is the best . Really, truly, the best dog in the world . Theirs is the best dog that ever lived, ever, ever, in the history of the known universe. Welcome to the dog park!  It’s a playground for dogs in the big city. Here, four sixth graders (and their dogs!) overlap on one hilarious and important June weekend.      Ezra needs to find his lost dog.     Cup-Cup needs a friend. (She also needs to learn to walk on a leash.)     Mei-Alice wonders if anyone will ever understand her.     Panda wonders what will happen if she breaks the rules.     Kaleb is covering up a terrible mistake.     Grover and Lottie are making lots of terrible mistakes. (Some of them are disgusting.)     And Jilly needs to make a new life in a new place.      On this almost-summer weekend, a series of surprises, mishaps, and misunderstandings will end up changing all of their lives.
