Luke ranks at #171 with 601 entries, and the name belongs to a category that under-performs slightly on pet leaderboards: classic biblical-Greek male names that dominate baby charts but do not always carry the same momentum into pet adoption. Luke is the most popular of that cluster on our pet data.
The biblical-classical male cluster
Luke shares a register with Jake, Sam, and Simon — short, biblical-rooted male names that read as friendly and grounded rather than grand. The blunt one-syllable shape works for dogs, but pet owners often pass on names this directly tied to baby naming because the human associations feel too specific. Luke gets enough use to land on the leaderboard, but it under-indexes relative to its SSA chart position.
One counter-reading: Star Wars's Luke Skywalker is a real but secondary anchor. A meaningful share of pet Lukes are named for the character, particularly among owners in the 30-45 age range who grew up with the original trilogy. Those Lukes tend to land on shepherds, retrievers, and large mixed breeds.
Sound register and breed fit
The hard K ending gives Luke a clean recall sound, and the open OO vowel carries well at distance. The name lands across mid-sized to large dogs at higher rates than for cats. The Luke baby name page shows the human chart, where it sits in the SSA top 50 and has held steady there for over a decade. Pet owners who pick Luke often have other male names from the same biblical-classical tier on their shortlist, including Sam and Jake, and the choice usually comes down to syllable rhythm rather than meaning.
