Styles Silverbark is the pitbull who owns station WFIDO, as seen in the Dog City episode "Radio Daze." A budget conscious dog, Silverbark hires Ace Hart because of his low rates. When accidents plague top-rated show It's a Dog's Life, he cares less about the cast's safety so much as the possibility of their missing a broadcast. Mr. Silverbark is pleased, however, when Ace's confrontation with the culprit leads to a dramatic on-air broadcast garnering high ratings. His name is a reference to news director Miles Silverburn on Murphy Brown.
