Buster's in big trouble. He's been dragged to Dog Court for breaking one of the most sacred of all dog rules: Never, ever talk to a human, or let a human know how smart you really are. But he swears he had a good reason! The boy he's been taking care of, Tonio, needed his help in a big way. You see, Tonio is afraid all the time - afraid of saying or doing the wrong thing, afraid of making a fool of himself or (even worse) hurting someone else's feelings. His doctor thinks having a therapy dog will help his anxiety - and Buster wants to help. He really wants to help. Even if it means breaking the rules. . . .
