Timmy ranks #554 with 224 entries, registered male. The name carries a specific Lassie-era cultural anchor — Timmy Martin from the long-running CBS series Lassie (1957-1964), whose name became near-shorthand for boy-and-his-dog narratives. The pet version of the name often inverts the original setup, making the pet itself Timmy.
The Lassie lineage
Timmy clusters with Lassie, Old Yeller, and other classic-era boy-and-dog references in the mid-century-Americana pet-naming cohort. Owners reaching for Timmy are usually older — boomers and early Gen X who grew up watching the show in syndication — or deliberately reaching for the vintage register from a younger position.
Breed lean and sound fit
Two syllables (TIM-ee), front-stressed, with an open trailing -ee that calls cleanly. Timmy shows up disproportionately on small-and-mid-size friendly breeds — Beagles, Cocker Spaniels, Shih Tzus, and rescue mixes with approachable-faced silhouettes. The name's diminutive register skews the breed pattern toward smaller dogs.
The South Park counter-reading
A real cohort of millennial owners reach the name through Timmy from South Park (introduced 2000). The reading is generational and lands on a different owner profile than the Lassie register. The Timmy human name page shows the SSA chart peaking in the 1950s-60s and softening since, confirming the lag pattern that drives current pet-naming.
The two cohorts (Lassie-era and South Park-era) rarely overlap. Owners are usually pulling from one cultural register or the other, with very few households reaching the name from both directions simultaneously.
