This tool counts dogs with a given name in the official open dog-licence records of New York City, Seattle, Cambridge (MA) and Zurich — 382,636 named dogs as of November 2026.

How it is worked out

Matching a name

We strip accents, punctuation and case, and keep the words: “José” is JOSE, “Mr. Peanut” is MR PEANUT. A name must match exactly; “Luna Belle” is its own name. Placeholders such as “Unknown” or “Name not provided”, and names under two letters, are left out.

Counting dogs

Counts are distinct dogs per city, added up; the four cities do not overlap. New York: one dog per unique name, sex, birth date, breed and ZIP code (334,091). Seattle: one per licence number (25,596). Cambridge: one per unique name, breed, birth year, sex and masked location (12,867). Zurich: the latest register snapshot (10,082). Total 382,636 dogs and 42,545 different names.

Limits of the count

Two dogs with an identical profile in one New York ZIP code merge into one, and a dog that moved ZIP code can count twice. The time windows differ by city, and New York's includes licences since 2014. Unlicensed dogs are not in any registry.

Rank and “1 in N”

Names are ranked by total; equal totals share a rank. “1 in N” is 382,636 divided by the name's total, rounded.

Breeds

Breeds are as recorded in New York, Seattle and Cambridge licences (Zurich's file has none), grouped into twelve: poodle and doodles, Labrador, golden retriever, pit bull, chihuahua, shih tzu, Yorkie, shepherd, Frenchie and bulldogs, Maltese and bichon, dachshund, and mixed and other. Percentages are of dogs with a recorded breed, shown when at least five have one.

Girls, trend, ZIP codes

The share of girls is shown when at least ten dogs have a recorded sex (Seattle records none). The trend compares births in 2020–2024 with 2010–2014 as a share of all births in those years: rising at 125 % or more, falling at 80 % or less, no label under 30 dogs. ZIP codes are New York's top three, shown only with two or more dogs.

The picture

Each painted dog stands for 1, 2, 5, 10, 20, 50, 100, 200 or 500 dogs, the smallest step that keeps the lawn at 60 dogs or fewer. Their breeds are the name's breed mix, split by largest remainder. A name with 25 dogs or fewer gets the small yard; otherwise the scene is the city where the name is the largest share of that city's dogs: a city park for New York or Cambridge, a beach for Seattle, snow for Zurich. The same name always draws the same park.

Spellings and neighbours

“Spelled differently?” lists names with at least five dogs that are one letter away (two for names of six letters or more). Neighbours are the two names above and below on the leaderboard.

Korean input

Hangul is turned into Latin letters: first a short list of 25 names that are English words (초코 is Choco), then a sound-by-sound spelling with one rule (a final consonant moves to a following vowel: 별이 is Byeori), then, for names ending in 이, the stem. The first spelling on record is shown, and every spelling tried is listed with its count.

About Korean data

Korea has no published dog-name data. The Ministry of Agriculture, Food and Rural Affairs reports 3.49 million cumulative registrations, dogs and cats together (May 27, 2025), with no name statistics, and local-government files on data.go.kr carry totals only. Private survey reports are not used here. Korean names are looked up in the four cities' records and never shown as Korean counts.

Good to know

Not a census. Counts are dogs in four cities' licence records, never an estimate for a country. Unlicensed dogs are missing.

The records include past licences. A count is not a count of dogs living today.

Breeds are as recorded in licences. Nothing here is veterinary or breed advice.

Made by plusbeauxjours from open city data. Not a product of, or endorsed by, New York City, Seattle, Cambridge or Zurich. The licence tag in the picture is ours, not a city's.

Questions

Where do these numbers come from?

From four official open dog-licence registries: New York City, Seattle, Cambridge (Massachusetts) and Zurich. We downloaded them on November 14, 2026 and counted each dog once. Nothing is estimated, and no registry is contacted when you type.

Is this how many dogs in the US have this name?

No. It is the number in these four registries only, 382,636 named dogs in all. We never scale it up to a national figure. Dogs without a licence are not in any registry, and many dogs are never licensed.

What does rising mean?

We compare dogs born in 2020–2024 with dogs born in 2010–2014, as a share of all dogs born in those years. Rising means the name's share grew by a quarter or more; falling means it dropped by a fifth or more. Names with fewer than 30 such dogs get no label.

Are dogs counted twice?

We remove repeats inside each city: New York lists licence periods, so a dog is one unique name, sex, birth date, breed and ZIP code. Two dogs with an identical profile in one ZIP code merge into one, and a dog that moved ZIP code can count twice. The records also include past licences, back to 2014 in New York.
