Precious Pupp, one of the two backup features behind Atom Ant, presented a mangy, layabout mongrel dog who somehow manages to foil any challenge that comes his way. Don Messick provided the sound effects for Precious, including an all-too-familiar-by-now laugh that Messick later transferred to Muttley (Wacky Races, 1968). Janet Waldo spoke for Precious' owner, Granny Sweet, who got around on a motor scooter, staying active at her advanced age.

It's just too bad that Hanna-Barbera never saw fit to bring Precious back in later years, although I suspect strongly that Goober might be of the same scraggly breed......!
