When Buster comes to live at Roger's house as a shy puppy, he has a lot to learn. Thank goodness Phoebe, an older and wiser dog, is there to teach him a few tricks. Top dog Phoebe has a plan to teach Buster how to collect and train bones to stay. Why then are Buster's bones mysteriously disappearing? Buster may be young and somewhat gullible, but he's also good-hearted, generous, and smart enough to figure out the mystery on his own. He also learns a lesson on making and keeping friends.
