All Dogs Go to Heaven: The Series - Season 3 (1998)

When David has to write a report on 'dogs,' Charlie and Itchy work to inspire him by relating events of how helpful pooches have been for mankind down through the ages.

Charlie, dissatisfied with his common life, wants to trade places with Thor, a rich show dog who looks like him.

Charlie is so lazy that he relies on futuristic gadgets, and because he is too lazy to clean up the apartment, he has inconvenienced everyone to the point where they have no choice but to have their New Years party at Carface's. He has a dream of being in the 23rd century where dogs are oppressed by the Great Deliverer. When not only is every other dog brainwashed by the Great Deliverer himself, and he turns out to resemble the mailman he barked at earlier (with a voice projector to make it sound like it was a lot of vicious dogs), Charlie regrets his laziness and ...

Charlie, intending to try a brand of dog food called Happy Hound, does, only because it was tainted with a mutation chemical (thanks to Carface and Killer), he turns into a monster. Eventually, after Itchy has saved Charlie, the latter never wants to have anything to do with Happy Hound, not even to see it. So when Sasha apologizes to him for not believing the events, brings it out, and offers it, Charlie knocks it off her paws, to so much fury of Sasha that she ejects him.

Charlie is supposed to train three juvenile angels-in-training, but he messes up by training, military-style, them not to serve mankind, but to serve him (snacks, much to Itchy's dismay), so they do badly. Meanwhile, Carface and Killer operate a machine called the HeelBoy 2000 that will turn dogs evil and make them work for him, and even Charlie's attempted skills to whack the machine doesn't work. He won't try to use the puppies because he hadn't trained them or ask Annabelle because she'll find out. They demonstrate this on a Chihuahua named Carlos, just as they had...

Itchy (having his snout bandaged by Sasha after chasing a parked car) tells Charlie (not to mention Sasha) a story about how Double-Dog Dare (as Charlie Barkin is depicted) saved the world in order to get him on a mission alone.

Charlie tries to convince Itchy to be rich and famous by hiding his stray life to impress Bess at her Show Dog School reunion.

When a bag of dog food falls out from the back of a truck, one puppy finds it and decides to take it home, but so does another, and they both fight over it. When Charlie and Itchy see this, they tell them to stop, with Charlie threatening to take the bag for himself and Itchy otherwise. He begins to tell them a story about how he and Itchy first met, and when their friendship began.

Charlie has an obsession with heroism and getting rewarded that he gets Itchy in the water so he can come to his rescue, but when he gets his reward, this option does not work out.

Charlie takes Itchy into an abandoned mansion in an attempt to cure his fears.

Belladonna manages to put Charlie on trial when he misuses a Miracle Dog tag. If Charlie is guilty, he would be permanently working for Belladonna.
