The 1989 original
- Though "What's Mine Is Yours" is often criticized for being way too cutesy, it's still the first time we see Charlie's kinder side, bringing some hungry puppies food and then teaching them about sharing. While the sharing lesson is rather half-assed, his fondness for the puppies is sincere.
- Charlie's last good-bye to Anne Marie. It's the saddest part of the whole film because of how real the love between them is.
- After spending the whole movie being a sarcastic, greedy, arrogant, unrepentant jerk, Charlie tells Anne Marie that he's sorry for what he put her through and means every word of it, as evidenced by the tears running down his face. Not only does he redeem himself by saving her life, the last thing he gets to do before ascending to heaven is the one thing he never got to do when he was alive: apologize.
- It's subtle (it probably wasn't even intentional), but Anne Marie sounds like she knows what Charlie's talking about when he says he has to go away now and accepts it for what it is.
- Itchy, who spends the whole movie treating Anne Marie like The Load, willingly taking Charlie's mantle as her comforter and friend, tucking her doll into her arms and laying his head close to hers protectively. Anne-Marie promises Charlie to always take care of Itchy for him.
- This also means that Charlie redeems himself in another way by fulfilling his promises to his two best friends. He finds Anne-Marie parents and Itchy is now safe from Carface.
- Charlie also decides not to wake Itchy up, lest he traumatize him even more by seeing his best friend as a ghost. Whether he should have or not is another argument (as Itchy appears to have cried himself to sleep), but he's definitely safer than he's ever been, so Charlie decides to let this sleeping dog lie.
- The fact that all of this leads to Charlie regaining his place in heaven. He literally earns his happy ending. And since all dogs go to heaven, that says something.
- The Running Gag of Charlie getting disgusted when Anne Marie kisses him on the nose concluding with him happily accepting it here.
- Itchy's complete dedication to Charlie, begrudgingly following his lead even when he knows it'll get them in trouble or worse. Why? "Because... because you're my friend."
- Itchy telling Charlie that keeping Anne-Marie isn't business any more and that he's in love with her. Charlie denies it, only because Itchy is accusing him of letting his emotions get in the way, but as we see at the end, Itchy is completely right.
Anne-Marie: Good-bye, Charlie. I love you.Charlie: Yeah. I love you too.
- Even the aptly named Big-Lipped Alligator Moment is kind of sweet. Despite his (and the audience's) initial confusion, Charlie eventually rolls with it and sings merrily with King Gator. Not to mention, the whole thing manages to save Anne Marie from being eaten. It also leads to King Gator returning at the climax to defeat Carface once and for all.
- Charlie dancing with the Heavenly Whippet. The guy oozes charm in that whole bit.
- Charlie winking at the audience saying "He'll be back" in The Stinger as Carface is chased down by the heavenly whippet. While it's obviously a joke, it almost feels like he's reassuring us that this is the end of their mortality, but not their adventures.
- Plus, given that Charlie was able to return to heaven even after being told the same thing, the final line "He'll be back" could also mean that redemption for Carface is not only possible, but inevitable. After all, all dogs go to heaven.
The TV Series
- Charlie and Itchy's surprisingly cute origin story about how a bad boy street dog and a mistreated house pet came to be buds in "When Hairy Met Silly".
- Carface's long-coming Heel–Face Turn at the end of A Christmas Carol. He doesn't just become a nicer person, he saves the world!
Carface: (handing out gifts to the pups) "Don't think that this is an every-day thing. I've still got a business to run, you know."
(Sasha gives him a kiss on the cheek)
Sasha: "As least you were sweet for one day."
