Zorro ranks at #617 with 200 entries, registered male. The name is the Spanish word for fox and the title of the masked-vigilante pulp character first published in 1919. Zorro-the-dog is usually the dog with the dark mask marking around the eyes, named for the visual.
The masked-marking naming logic
A large share of registry Zorros are dogs with raccoon-style or bandit-style facial markings: a darker patch over the eyes that reads as a mask. The naming is direct visual reference to the masked-vigilante character, and the breeds that carry the marking most reliably are Huskies, German Shepherds, Malamutes, and shelter mixes with shepherd lineage.
The character lineage
Zorro originated in Johnston McCulley's 1919 pulp story The Curse of Capistrano and was carried into wide American visibility by Douglas Fairbanks's 1920 film, the long-running 1957 Disney TV series with Guy Williams, and the 1998 Antonio Banderas film The Mask of Zorro. The character is a Spanish-California aristocrat by day and a masked sword-fighter by night, and the name carries that swashbuckling register cleanly onto a dog.
Sound and the broader cohort
Two syllables, front-stressed (ZOR-roh), with the rolled R giving the name a Spanish-language phonetic anchor that owners frequently lean into. Zorro sits with Bandit, Mask, and Diego in the masked-marking and Spanish-character pet pocket. The human Zorro page shows minimal SSA presence; pet Zorro owns the cultural space without competition.
