Winston. Walter. Watson. Wally. Willie. Winnie. The W list has a period to it that no other letter does, and it is roughly the 1930s. This is the letter where owners reach for a name that sounds like somebody's grandfather, and they reach for it often: 75 registrations per name, above the catalogue rate, from only 227 names.
Strongly male, and it is the vocabulary doing it
95 measure male against 34 female, one of the widest gaps in the catalogue. The Edwardian given names that make up the letter were mostly men's names, and the letter inherited the imbalance wholesale.
The -ie ending is what stops it being stuffy
59 of the letter ends in -y or -ie: Wally, Willie, Winnie, Whiskey. A formal Edwardian name with a diminutive ending is exactly the joke people are making when they call a small dog Winston, and the data shows they make it a lot.
A W barely arrives
The sound is a glide — the mouth is already moving into the vowel before anything else has happened — so an initial W does very little to make a name audible. What carries in Winston is the st. Only 30 of the letter is four letters or fewer, so there is not much here for someone who wants short and loud.

Why do W pet names sound old-fashioned?

Are W names male?

Every count on this site is a tally of real registrations: pet licences and shelter intakes published as open data by New York, Seattle, Austin, Montgomery County, Cambridge, Zurich, Basel and four Australian councils. Popularity here is the average share a name holds across those registers, so a name common in a small city is not buried by one common in a large one. Five of the eleven registers are North American and they supply 86% of the records, so read the ordering as naming in those places rather than worldwide.
