The story begins with strays or wild animals living on the streets or in the wild. They may fall for a pet animal or take a liking to a human they meet. In the end, they are adopted by a loving human family and given a name. Thing is, they've had that exact same name throughout the entire movie, but were only called that by their animal friends.
May fall under the category of Contrived Coincidence, or it could be a form of Translation Convention from Animal Talk to English. See also Namedar. Compare and contrast with Animal Naming Conventions.
- Subverted in a The Far Side comic where it turns out that dogs' own names for themselves are things like "Thundara, Princess of the Universe".
- The Dogfather is a Harry Potter AU in which Sirius Black escapes from Azkaban years before Harry goes to Hogwarts and gets himself, in his "Padfoot" dog Animagus form, chosen as Harry's pet dog. (It's also an AU in which Harry is being raised by a nicer family than the Dursleys who let him have a pet dog.) Harry's parents decide to name the new dog Padfoot. It's justified by saying that they choose the name because he reminds them of a dog toy Harry had when he was very young, that he called Padfoot (which, unbeknownst to them, was because the toy reminded baby Harry of the real Padfoot).
- Averted in the My Little Pony: Friendship Is Magic fanfic Sun Princess. Winona refers to herself as "Faithful Student" because she considers herself extremely faithful to her owner, Applejack (who she calls "Sun Princess").
- In Haibane Renmei, it's specifically mentioned that the Haibane (humanoid beings with angel wings and halos) don't remember their previous names. They're named after the dreams they have prior to hatching. In Before We Had Wings, their previous names just so happen to be the same as their Haibane names.
- Lady and the Tramp:
- The first film subverts this trope. Tramp is called by many names by many owners. He is "Butch" to Tony, "Mike" to an Irish family, and "Fritzi" to a German family, and it is implied that there are many more. As for being called "Tramp" when he's adopted by the Darlings, this is never shown in the movie, although it might be present in the comics and the sequel. Even that mildly subverts it, as he is called "Tramp" at the end instead of "the Tramp".
- In Lady and the Tramp II: Scamp's Adventure, the stray to whom Scamp has taken a liking is adopted by the family and named Angel, which she's been called throughout the movie.
- In Ratatouille, this is averted. While Remy's real name is, well, Remy, Linguini names him Little Chef.
- Averted in Oliver & Company, where Oliver's dog friends only call him "cat," "kitty," "child" or "kid" until Jenny names him "Oliver." Only the voiceover song "Once Upon a Time in New York City" calls him Oliver from the start, and that can be chalked up to the singer being an omniscient narrator.
- Ferdinand has the titular character run away from home and be adopted by another family, yet keeps the same name.
- In Spunky's Diary by Janette Oke, Spunky is named by his mother. When he's bought by a family, they decide to name him Spunky because of his energy, and the puppy is not at all surprised, since that was already his name.
- Averted in the original literary version of The Jungle Book. The protagonist is named Mowgli by his wolf foster parents (though he is usually called "little brother" by the other animals, at least until he gets bigger) but the humans who adopt him when he returns to the world of Men call him Nathoo, after their long-lost son. (His new mother believes that he really is Nathoo returned at first, but it is clear that Nathoo was lost at a later age than Mowgli was - she recalls giving Nathoo shoes, but Mowgli was lost before he could walk, and she sees from how his toes are splayed that he has never worn shoes.)
- In Hank the Cowdog, Hank is content with the Slim naming him that, as that was the name his mother gave him.
- The children's book Zucchini is about a ferret that escapes from the zoo and is adopted by an elementary school class. The students name him Zucchini, the name he had in the zoo. Somewhat justified, as the students have heard about the escape and name the ferret after himself.
- Subverted in Dogsbody by Diana Wynne Jones. In a world where stars are actually sentient creatures with godlike powers, Sirius is framed for murdering a dwarf star, and banished to Earth to search for a vital piece of evidence — and, in the process, forced to be reborn as a mortal... a mortal dog, to be precise. When he is later adopted by a young girl, she mulls over his name for a long time, but eventually settles on "Leo" — lampshading it later, when she learns about 'The Dog-Star, Sirius' at school, and comments that it would've been a better name.
- Played straighter later in the book when Sirius meets Miss Smith, who is generally presented as wise and perceptive and who quickly decides that she's going to call him "Sirius".
- Olga da Polga of the book series of the same name takes it upon herself to make sure this trope happens. After hearing her new family discussing various names for her and being disgusted by all of them, she works hard all through the night, tracing the words "Olga da Polga" in the sawdust of her cage.
- Averted in Catseye by Andre Norton: main character Troy Horan communicates telepathically with a group of animals — a pair of foxes, a pair of cats, and a kinkajou — with intelligence upgraded to human level. When he asks about their names, the female cat says somewhat disdainfully that they were given "Man's names!", and Troy senses a hint "that there were other forms of identification more subtle and intelligent, beyond the reach of a mere human." There's a touch of Hypocritical Humor there, as she told him that after she referred to the male fox by his human-given name.
- Averted by The Book of the Film Free Willy, in which it's revealed that Willy's "orca name" is Three Spots (referencing the dots under his chin), and the name change is listed among the many ways that life in an aquarium is highly confusing and frightening.
- Averted in the Remy Chandler series. When Remy picks the puppy that will become his pet, he asks the puppy what his name is. Pretty reasonable, given that Remy who is really Remiel, a seraph and a warrior of God, can understand all languages, including the languages of animals. The puppy replies he's called "Fifth of Seven." Remy names Fifth of Seven Marlowe, after his favorite fictional detective.
- Played with in Promise of the Wolves. Kaala's name is wolf-speak for "Daughter of the Moon". Her human friend names her "Silvermoon", and Kaala is surprised and pleased that it's so close. It's a minor case of Fridge Brilliance: Kaala has a birthmark on her pelt in the rough shape of a crescent moon, and that was how the pack chose her name when she was born. It makes sense that TaLi would also see it and think the same way.
- Warrior Cats:
- We see in Barley's backstory that he always had the name Barley, even when he lived in the city; the name didn't initially come from the humans who own the farm he lives on. However, in the Ravenpaw's Path graphic novel trilogy, one of the humans calls him "Barley", so we can assume that they just happened to name him his actual name.
- Dovewing's name as a ThunderClan warrior is almost exactly the same as when she was an Ancient named Dove's Wing.
- An understandably rare human example in The Edge Chronicles where Twig is captured as a pet for a Termagant Trog, while pretending to be unable to speak he starts chanting "Twig, Twig, Twig." which causes her to decide this is a good name for him.
- The Moonbeam series of graded readers is about a chimp who gets captured and taken to America to be part of the space program. Even before she is captured, when she's just a wild chimp running around the jungle, the narration refers to her as "Moonbeam", the name her NASA handlers give her; however, given the reading level the early books are pitched at it might just be that the authors wanted to avoid confusing beginner readers with an explanation of "the chimp who would later be called Moonbeam but at this point didn't have a name".
- Perhaps averted in Black Beauty in the case of the titular character - despite the title, only one of his various owners ever calls him Black Beauty. His other names include Darky and Blackjack. However, we don't really know what he calls himself, given that it is narrated from first person and the other horses don't call him by name, so he could regard his name as being Black Beauty. However, Ginger definitely fits in with the trope, and so does Merrylegs.
- Averted in Windrusher. A cat named "Tony" is abandoned by his owners. Other animals call Tony "Windrusher" instead of "Tony".
- Averted in the novelization of Annie (1982), which narrates Annie's adoption of Sandy from Sandy's point-of-view. In his mind he calls himself "Scram," because that's what most humans "call" him, until Annie gives him his new name.
- The Lone Gunmen: The LG rescue someone who has contacted them for help, who turns out to be a sapient chimpanzee who communicates via email and voice synthisizer. He complains of the name he's been given, "Peanuts."
Chimp: Please stop addressing me by my slave name.Yves: How do you prefer we address you?Chimp: By the name I have given myself: Simon White-Thatch Potentloins.
- 101 Dalmatian Street both averts and plays this straight. In "My Fair Dolly", Dolly gets a random Human so she can compete against Clarissa in a Dog Show. The Human, upon seeing Dolly, calls her Camilla. In the Episode; "Doggie Da Vinci", Da Vinci becomes a local celebrity for her art work. When she is being chased by the crowd, they call out different names to her, such as "Labrador Dali", before settling on calling her "Doggie Da Vinci". Dylan lampshades this, questioning how the Humans knew what her name is, and Dolly figuring that Humans are smarter than she thought they were.
- At the end of the Christmas Special Christopher the Christmas Tree, when the title character becomes the president's Christmas tree, the president makes a speech about why he's decided to give the tree a name: Christopher.
- Averted at the end of the first Pound Puppies (2010) episode, where Yipper is matched up with a little boy who decides to name him Bob, to the bemusement of the other pound puppies. Also, averted with Taboo, who is called "Lucky" by his Human. Played straight with Niblet's sister Rebound (so named because she's always returned) after she's adopted by McLeish's mother Agatha.
- Averted with dolphins in The Penguins of Madagascar. People called Doris "Dotty" and Dr. Blowhole "Flippy".
