🐾 Famous fictional pets (and their real stories)
Some of the most beloved characters in fiction are animals. Borrowing their names gives your pet a ready-made legacy.
Winnie
Winnie-the-Pooh (1926)
Named after a real bear. Canadian army vet Harry Colebourn named a black bear cub Winnie after his hometown, Winnipeg, and left her at London Zoo in 1914. Christopher Robin Milne loved her so much he renamed his teddy bear Winnie (London Zoo).
Toto
The Wonderful Wizard of Oz (1900)
Dorothy's loyal little dog. Perfect for a small terrier who follows you everywhere.
Buck
The Call of the Wild (1903)
Jack London's brave sled dog. Great for a big, adventurous dog.
Snowy
The Adventures of Tintin
Tintin's clever white terrier (Milou in the original French). Ideal for a white dog.
Hedwig & Crookshanks
Harry Potter
Harry's snowy owl and Hermione's ginger cat. Hedwig suits a white bird or cat; Crookshanks a fluffy orange cat.
Fang
Harry Potter
Hagrid's huge, cowardly boarhound: a perfect ironic name for a gentle giant.
Aslan
The Chronicles of Narnia
The noble lion. For a majestic, golden pet.
Cheshire
Alice's Adventures in Wonderland (1865)
The grinning, disappearing cat. Made for a mysterious cat with a smug face.

📊 What the data says about character names
Character names rise and fall with what we're watching. In Rover's 2023 report, Wednesday Addams rose 297% and Enid 217% as dog names, the year after the Netflix series Wednesday premiered (Rover via FOX). In the UK, Rover tracked Obi-Wan up 413% and Sabrina up 312% in 2025 (Rover UK). And for 2026, Rover's top trending dog name was Rumi, from the animated film KPop Demon Hunters (Rover via FOX 9).
Why do we do it? Naming researchers see giving pets human or person-like names as a sign that owners treat them as family members (Names, 2025). A character name adds a story on top: it says something about what you love, and it often starts a conversation with fellow fans at the dog park. Want to understand more? Read our psychology of pet naming.
💡 Making a character name work every day
- Pass the vet waiting-room test. If hearing the name called out makes you smile, go for it. If you'd cringe, keep it as a nickname.
- Plan the nickname. "Daenerys Stormborn" will become "Dany" by day two. Make sure you like the short version.
- Avoid cue sound-alikes. The AKC advises skipping names that sound like commands, so think twice about "Kit" (sit) or "Bo" (no).
- Think about strangers. Villain names like Voldemort can make groomers or neighbors hesitate. Choose a softer one if your dog is big or shy.
- Choose clarity. "T'Challa" is memorable but hard to spell; "Panther" captures the same vibe.
