* AdoredByTheNetwork: Creator/CartoonNetwork and {{Creator/Boomerang}} used to air this show a lot back in the mid-90s, 2000s, and early-2010s. Cartoon Network had a preschool block and this was one of the few cartoons to still air reruns on the channel after it got cancelled. It was also the youngest show to air at Boomerang's launch.
* CastTheRunnerUp: According to Tom Ruegger, Creator/ScottMenville was originally considered for Freddie before being cast as Red Herring.
* ChildrenVoicingChildren: Fred, Daphne, and Velma are all voiced by actual children, while Don Messick and Casey Kasem reprise their respective roles as Scooby and Shaggy. Fred's voice actor apparently went through puberty as his voice is slightly deeper in later episodes.
* CrossDressingVoice:
** Creator/KathSoucie voiced Bobby of the Brainy Bunch from “For Letter or for Worse”.
** Red Herring’s aunt from "Night of the Boogy Biker" is voiced by Creator/ScottMenville.
* DawsonCasting: Shaggy and Scooby, with Creator/CaseyKasem (who was in his late 50s) and Creator/DonMessick (who was in his early 60s) playing the young versions of their regular characters.
* FollowTheLeader: In addition to the SpinoffBabies trend, this show was also Creator/HannaBarbera's answer to the successful ''WesternAnimation/MightyMouseTheNewAdventures'' series by Creator/RalphBakshi that premiered on Creator/{{CBS}} the previous year, produced in the same [[SelfParody satirical manner]].
* TheOtherDarrin:
** Carl Stevens replaced Creator/FrankWelker as Fred, making this the first Scooby project where Welker didn't voice him. Fred would not be voiced by anyone other than Welker again until the 2020 film, ''WesternAnimation/{{Scoob}}''.
** Creator/KellieMartin replaces Stephaniana Christopherson and Heather North as Daphne.
** Christina Lange replaces Nicole Jaffe, Pat Stevens, and Marla Frumkin as Velma.
* RereleasedForFree: The whole series is free to watch on Tubi starting on June 2023.
* RoleReprise: Creator/CaseyKasem and Creator/DonMessick reprise their roles of Shaggy and Scooby-Doo, while Freddy, Daphne and Velma were voiced by new actors, making this the only installment of the ''Scooby'' franchise to not have Creator/FrankWelker[[note]]Although he did appear in "Chickenstein Lives!" as Fred's uncle, Eddie Jones[[/note]] cast as Fred[[note]]Until the release of ''WesternAnimation/{{Scoob}}'' in May 2020[[/note]]. This ended up being the last series where Scooby was voiced by Don Messick.[[note]]Though it would not the final instance, as he would continue to voice Scooby in other projects until the 1995 video game Scooby-Doo Mystery.[[/note]]
* TechnologyMarchesOn: Despite the show supposedly taking place in the early 60s, when the gang was younger prior to the original ''Scooby-Doo, Where Are You?'' premiering in 1969, some late 80s/early 90s technology was present. Velma often would type data in a large computer that would pop out of a briefcase, and Daphne could be seen with a cell phone (which was quite rare to see back then, but much more common today.)
* WhatCouldHaveBeen: Originally during production producer Tom Ruegger wanted Velma to say nothing but the word "Jinkies" throughout the entire series. After the first episode, new story editors were brought onboard to write episodes and decided to have Velma say more than just "Jinkies" which Ruegger thought would have made her more memorable.
* WorkingTitle: The show was originally called [[https://www.syfy.com/syfywire/a-pup-named-scooby-doo-history?fbclid=IwAR2vmjOyCuNOXjKfCvUNBpP0Zg4sgPlz6hgN0XJUEMwfE1rQjcLStKzWYWs Scooby Doo: The Puppy Years]] .
* WordOfGod: Scooby's two brothers names' had been a passed around joke studio wise (Scooby Doo has a brother named Howdy Doo?), but turned into actual characters for a cameo.
