Chewbacca ranks #458 with 267 entries, registered male. The name belongs entirely to a single source: Chewbacca the Wookiee from Star Wars (introduced 1977), Han Solo's loyal copilot. There is no other naming tradition feeding this word into pet-naming use, and the four-syllable length makes it one of the more committed picks on the chart.
The Star Wars lineage
Chewbacca's character is one of the most beloved animal-coded characters in pop culture: shaggy, devoted, vocal, and surprisingly emotional. Owners picking the full Chewbacca rather than the shortened Chewy are deliberately committing to the long form, often as a paperwork joke that becomes the daily call name. The visual reference is unmissable — big, hairy, brown.
Breed lean and visual fit
Chewbacca lands almost exclusively on large, brown, shaggy-coated breeds where the visual matches the namesake directly — Newfoundlands, Bernese Mountain Dogs, Tibetan Mastiffs, brown Standard Poodles, Old English Sheepdogs, and large brown shaggy mixed breeds. There is also a smaller cluster of long-coated German Shepherds and Belgian Tervurens. The breed-pattern is unusually tight.
The full-name commitment counter-reading
Worth flagging: Chewbacca as a written name is a commitment — vet forms, license registrations, and microchip tags will all carry the long version even when the daily call is just Chewy. Some owners eventually shorten to Chewy on the paperwork. The human Chewbacca page shows zero SSA presence, confirming this lives entirely on the pet side.
