UK vs US Dog Naming Divergence — Agria UK and AKC 2022 vs 2025
The UK and US dog-naming markets share roughly half their top-10 names but the unshared half is the most informative half. The UK list runs on a soft-vowel, period-drama register (Bertie, Reggie, Monty, Poppy, Coco, Winnie, Bonnie) while the US list is drifting toward an American-Western working-dog register (Hank, Gus, Duke, Maverick). The UK list also churns harder than the US list — 6 of the 20 UK top-10 slots (combined male + female) turned over between 2022 and 2025.
Side-by-side: UK 2025 vs US 2025 (gender-split)
Each list shows the 2025 top 10 by gender. Shaded rows mark names that appear in both markets at the same rank tier.
🇬🇧 UK 2025 — Female (Agria)
🇺🇸 US 2025 — Female (AKC)
Shared, UK-only, US-only
Across the female lists, 5 of 10 names appear in both the UK and US 2025 top 10: Luna, Bella, Daisy, Willow, Ruby. That's a 50% overlap — the female half of the market is genuinely transatlantic. The other half divides cleanly: the UK keeps the period-drama soft-vowel set (Poppy, Bonnie, Lola, Coco, Winnie) while the US keeps a more astronomical / botanical / coined-modern set (Lucy, Maggie, Penny, Nova, Sadie).
On the male side the overlap is sharper: 5 of 10 names appear in both lists (Teddy, Charlie, Max, Cooper, Bear). The unshared half tells the strongest cultural-fingerprint story in the entire dataset. The UK keeps a "named-after-a-grandfather" register — Milo, Buddy, Monty, Reggie, Bertie — short, vowel-ended, slightly archaic, the kind of name that reads as "London brunch with a Cockapoo." The US keeps an entirely different register — Hank, Gus, Duke, Maverick, Finn — Hank, Gus, Duke, and Maverick all entered the AKC top 10 in 2025 specifically, replacing more conventional 2024 entries with names that read as American-Western working-dog culture.
UK 2022 → 2025 churn
The UK top 10 absorbed 6 new names between 2022 and 2025 and lost 6 names from the 2022 list. This is the largest 3-year list-churn we observe across any tracked national market.
↑ Entered the UK top 10 (2022 → 2025)
Luna entering at #1 — directly into the top spot, having been absent from the 2022 top 10 entirely — is the single most striking single-name move in the dataset. UK Luna closes the transatlantic gap that had existed in 2022 (Luna was already AKC US #1 then). Coco, Winnie, Monty, Bear, and Bertie filled the remaining new slots — all are soft-vowel UK-register names consistent with what the UK list already preferred.
↓ Exited the UK top 10 (2022 → 2025)
Notable exits include Mabel (UK #8 in 2022), Nala (UK #10), Rosie (UK #7), and "Puppy" (UK #4 — a generic male top 10 entry that has been displaced by names with sharper cultural identity). Mabel and Nala leaving the list while Bonnie stays is interesting: all three are short two-syllable female names with similar phonetics, but only Bonnie has the period-drama / grandmother-name register the UK list is consolidating around.
Where the divergence comes from
The UK and US dog-naming markets are converging on a single dominant top of the female list (Luna, Bella, Daisy, Lucy, Ruby, Willow all appear in both 2025 lists) but diverging on everything else. That pattern repeats what English-language baby-naming research has shown for decades: the most popular names converge across the Anglosphere because mass media is global, but the second tier diverges because cultural register is local. Bridgerton has a stronger cultural foothold in the UK than in the US, and the UK male list reflects that — Bertie, Reggie, Monty, Buddy are all names that read as "Regency revival" or "post-war Britain." The US male list, by contrast, is showing American-Western register saturation: Hank, Gus, Duke, Maverick all have working-dog or working-class connotations that travel poorly to the UK market.
The UK list also exhibits sharper churn for a structural reason: Agria UK's data comes from pet-insurance registrations, which capture a younger pet-owner cohort (UK pet insurance penetration is higher than US, and the average insured pet is younger). A younger cohort follows fashion harder. The AKC US data, by contrast, draws on registration data that captures purebred owners — a more conservative, slower-changing population. Some of the apparent UK volatility is methodological rather than cultural — but the directional story (UK absorbs Luna, US absorbs Hank) is real in either methodology.
What to expect for 2026 / 2027
Two predictions emerge directly from the data. First: the UK female list is most likely to lose Luna's #1 by 2027 — not because Luna will fall in absolute popularity but because the UK list has historically not held a name at #1 for more than two consecutive 3-year tracking windows, and the next Agria release will be the test. Second: the US male list will see Hank, Gus, Duke, and Maverick consolidate rather than retreat — three of the four have sustained cultural anchors (literary / film / sports) and the historical pattern for newcomers with cultural anchors is consolidation, not retreat. The UK male list is more open to an additional period-drama entrant in 2026; the US male list is more likely to stabilise at its current 2025 composition.
