In 1978, Joe Ruby & Ken Spears adapted a little known children's book, The Puppy Who Wanted a Boy, for the ABC Weekend Special. The episode proved so popular, with its annual replays, that ABC commissioned an ongoing Puppy series.
First, the adventures of Petey the Puppy were coupled with Scooby & Scrappy Doo in a hour-long block, which didn't really make much sense. The following year, Petey and pals were spun off into their own half-hour standalone series, under the title, The Puppy's Further Adventures, rechristened The Puppy's Great Adventures when the series went into all-rerun mode, first on ABC, then CBS.
Petey (voiced by Billy Jacoby here) doubles as narrator, and there was some sparks between Petey and Dolly (Nancy McKeon, The Facts of Life), too.
Edit, 12/20/17: The video previously posted has been deleted. Soon as we can find something, we'll have it here.
Too bad Cartoon Network is sitting on this one right now.
Merry Christmas, everyone. We're off until Friday.
