This is Bump of old Hanna Barbera's The Biskitts. One of the shows that were like the Smurfs that populated Saturday Morning in the 1980's.

The Biskitts are a group of tiny anthropomorphic dogs who live on Biskitt Island and are committed to guarding the crown jewels of Biskitt Castle. Modeled after Robin Hood, the Biskitts still serve their recently deceased king while performing good deeds for the underprivileged inhabitants of their tiny island. It is explained in the opening narration that due to their good reputation for responsibility and security, other kings have entrusted their treasures to be safeguarded by the Biskitts. The villain of the series is the king's mean-spirited, wasteful, younger brother King Max who rules the neighboring Lower Suburbia. In lieu of a proper coronation, Max constantly schemes to steal the royal treasure with the help of his hench-hounds Fang & Snarl and his jester Shecky. The Biskitts are also in danger of being captured and eaten by a large wildcat named Scratch.

Bump: Bump is the muscules on Biskitts. He protect his friends from danger. He was become friends with Shecky about their jokes. He is completely forgotten sometimes. He is friends with Waggs. He is a St. Bernard
