In the 1990s, PBS introduced young audiences to a canine star like none other: a Jack Russell terrier who imagined himself as characters from classic works of literature. The show was called Wishbone. Today there's a whole generation of adults who were first weaned on Mark Twain, the legend of Faust or the Greek epics through this series. Wishbone is also the first TV show Mo wrote for. Mo talks with Wishbone head writer Stephanie Simpson and dog trainer Jackie Kaptan about the show and the life and career of its beloved lead actor, a dog named Soccer.
