Precious Pupp was a loyal pooch to his owner Granny Sweet. The large, shaggy dog had a carefree attitude, but he proved especially adept at getting revenge on any who attempted to wrong either himself or Granny. Given that Granny Sweet had the disposition of a much younger and active woman — she participated in a variety of sports, and loved to zip around town on her motorcycle — Precious Pupp came across plenty of opportunities to defend her honor. His joy for the confrontations came across in an easily expressed, raspy laugh.
Six-minute Precious Pupp segments played alongside similar segments as part of The Atom Ant/Secret Squirrel Show. In total, Hanna-Barbera created twenty-six Precious Pupp episodes over the course of two seasons.
