* ActorAllusion:
** When the heavenly whippet looks in Charlie's records, his mother and father are named "Loni" and "Burt", and look like canine versions of Loni Anderson and Burt Reynolds (who were together at the time.) Loni also appears in the film as one of Charlie's "close friends".
** During his VillainSong, Red puts Carface in a barber's chair and proceeds to shave him, a clear ShoutOut to ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet''. George Hearn, who voiced Red, was also one of the many actors to have played the titular barber in the aforementioned musical.
* [[ActorAllusion Author Allusion]]: Don Bluth's birthday is also September 13, 1937. The idea that every human year is seven dog years is a myth - Charlie is about 25. Even though he seems older.
* TheDanza: Creator/CharlieSheen as Charlie in the sequel.
** Also goes with TheOtherDarrin, as Burt Reynolds played Charlie in the '89 film.
* ExecutiveMeddling: We were originally going to get to ''see Charlie's body'' flying off the pier. (This is that rare example of a good executive decision.)
** But many book adaptations of Don Bluth films include unused artwork. Therefore, the tie-in book for this film showed a very clear silhouette of Charlie's body flying alongside the car...
* HeyItsThatVoice: Charlie Barkin is [[SmokeyAndTheBandit Bandit]]
** Carface is [[Series/{{Alice1976}} Mel]]. Kiss his grits.
*** [[WesternAnimation/SpongeBobSquarePants Mermaid Man]] voices Carface in the sequel.
** Itchy is [[Film/{{Spaceballs}} Pizza the Hutt]], [[TheSecretOfNIMH Jeremy]], and [[WesternAnimation/AnAmericanTail Tiger]].
** Anne-Marie is [[TheLandBeforeTime Ducky]]
** King Gator is [[WesternAnimation/TheNightmareBeforeChristmas Oogie Boogie]]
** Killer is {{Gex}}, [[RockADoodle Hunch]], [[WesternAnimation/SpongeBobSquarePants The Dirty Bubble]], and a panelist on {{Match Game}}.
** Red is the original ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'' (see ActorAllusion on the main article).
** Sasha also sang some songs on WesternAnimation/PhineasAndFerb.
*** She was also Doofenshmirtz's ex-girlfriend in "Chez Platypus".
** In the series, Annabelle is [[Series/{{Cheers}} Frasier Crane's wife Lilith]].
** In Italy and Sweden, David was [[Film/{{Matilda}} Mikey Wormwood]].
* NonSingingVoice: In the first film. While Judith Eva Barsi was only Anne-Marie's speaking voice, the film developers had adult actress, Lana Beeson, to do the singing voice for Anne-Marie in the SugarWiki/{{heartwarming|Moments}} TearJerker song, "Soon You'll Come Home". Barsi did audition for the singing part but [[PaterFamilicide because she broke down in stress from events at home during the audition]], they didn't make her do the singing.
* RealitySubtext: Read [[http://z7.invisionfree.com/thegangoffive/index.php?showtopic=981 this message board post]]. Now try to watch the film without cringing violently. (The link doesn't make it explicit, but Creator/JudithBarsi was also the voice of Anne-Marie.) This may explain the above-mentioned FamilyFriendlyFirearms.
* TheRedStapler: Watching this movie WILL make you want to get a German Shepard.
* TroubledProduction: The sequel, according to [[WordOfGod the directors]], was originally animated in Dublin, Ireland (where Bluth's original studio, which produced the first film, used to take place before that). But then, after Screen Animation Ireland, the Dublin studio in charge of the animation, shut its doors, the animation has to be outsourced to several studios in countries like Taiwan, Korea, Canada, and Denmark in order for the film to meet up the deadline.
* WhatCouldHaveBeen: Charlie was a detective in the original draft and the film was going to be an anthology of three short stories.
** The Hell sequence was supposed to be a lot longer than it was in the movie.
* CharacterRecycling: David from the second All Dogs go to Heaven 2 can also be found in ''WesternAnimation/GrandmaGotRunOverByAReindeer'' as the movie's main protagonist ''Jake Spankenheimer''.
