Trevor is a Welsh name — from the place name Trefor, meaning "large homestead" — that reached peak American popularity in the 1990s and has been declining on baby charts since. For a male pet at rank 1045, it sits in the same generational nostalgia zone as Travis and Brandon: names that millennial owners remember from their own childhood cohort, now applied to pets with a fondness that's partly ironic and partly genuine.
The 90s Name Revival
Trevor peaked around #60 on U.S. baby name charts in the mid-1990s, which means millennial owners in their 30s grew up knowing several Trevors. Giving that name to a dog creates a specific comedic affect : the slightly out-of-fashion human name transferred to an animal without ceremony. It's in the same register as Brad, Chad, and similar era-specific names that have developed a gentle self-aware humor over time.
Sound and Function
TREV-er is two syllables, clear, with a strong opening consonant. It's an effective pet name from a purely functional standpoint — easy to say, distinctive, not likely to be confused with commands. The human version at Trevor traces the Welsh origin for owners interested in the etymology beyond the 90s cultural layer.
Breed Fit
Trevor lands well on medium-sized dogs with an easygoing personality — Golden Retrievers, Labs, breeds where an approachable human-sounding name feels right rather than incongruous. It doesn't demand a particular physical type, which makes it more flexible than many names at this tier.
