London ranks at #410 with 303 entries, leaning female. The name belongs to the place-name pet-naming register — capital cities, exotic destinations, and meaningful travel locations adopted as given names. London carries a polished, slightly sophisticated tone that fits the contemporary surname-and-place naming aesthetic.
The place-name register
London clusters with Sydney, Paris, Dakota, and Aspen in the place-name pet-naming cohort. Some owners pick the name for a specific personal connection — a memorable trip, a meaningful family tie to the city — while others are drawn to the sophisticated tone without a place anchor. The London baby name page shows the SSA chart climbing through the 2000s and 2010s for both boys and girls, though it leans female.
The Suite Life layer
The Suite Life of Zack and Cody (Disney Channel, 2005-2008) featured a character named London Tipton (Brenda Song), and that show shaped a generation of younger millennials' reference frame for the name. Owners who came of age during that era sometimes pick the name through this lens, sometimes consciously and sometimes not. The Yorkie association is part of the show's cultural footprint.
Sound and breed fit
The two-syllable shape (LUN-dun) has a soft front consonant and a closed trailing consonant, projection-friendly without being sharp. London lands disproportionately on small-to-medium dogs with confident-but-elegant temperaments — Yorkies, Maltipoos, Cavaliers, Frenchies, and small mixed breeds where the polished tone matches the visual.
