This is Lady 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.

Lady (voiced by B.J. Ward): Lady is the pretty one of the Biskitts. She is friends with Sweets and Wiggle. Sometimes she can be bossy. She is sometimes with the others Biskitts for adventures. She has a possible crush on either Waggs or Shiner, most likely because the latter has the same ego as her. She is an American Cocker Spaniel
