According to Yvan Delporte (Peyo's collaborator) Puppy was a product of Hanna-Barbera's formula to put a dog in all of its cartoons to broaden a show's appeal (due in part to the success of "Scooby Doo, Where are You?" which features a dog). However, when show writers created a blue Smurf-sized pet for Baby, Studio Peyo objected and helped remodel Puppy into a magical creature in the shape of a "real" dog.
"Puppy" was latter adapted as a comic story in 1990 under the title, "Puppy et les Schtroumpfs" ("Puppy and the Smurfs" in English). There are major differences between the comic adaptation and cartoon original:
- The Smurflings and Balthazar are absent in the comic version.
- Gargamel wanted to touch Puppy's locket so he can be latter's master, while in the cartoon version, he brought Puppy's existence to his godfather Balthazar who also desires to know about the locket's secrets.
- After escaping from Gargamel after being caught by him, Puppy lead Gargamel to the Smurf Village. None of this happened in the cartoon version.
- Baby opened Puppy's locket becoming his master after Gargamel entered the Smurf Village which allowed Puppy to attack Gargamel and chase him out of the Village. This was seen by some of the Smurfs. In the cartoon version, Baby opened Puppy's locket becoming his master in secret as well seeing its secrets. The Smurfs were never aware that Baby became Puppy's master.
While the Smurflings have a major role in "Stuck on Smurfs," none of them spoke a line.
