Bruce

Bruce is a Scottish surname of Old French origin, most likely derived from a place name in Normandy — possibly Brix or Le Brus — brought to Scotland by Robert de Brus, ancestor of the famous Robert the Bruce, King of Scotland. As a given name, it carries a strongly masculine, solid quality, evoking both Scottish highland strength and the kind of no-nonsense reliability that built empires.

Bruce ranks #137 among America's most popular pet names, and it occupies an interesting cultural space — a human name that has migrated to pets while retaining all its associations with strength and character. It suits companions with a robust, confident presence: the pet who knows what they want, moves with purpose, and commands respect without demanding it. There is also an undeniable superhero layer here, given Batman's alter ego Bruce Wayne, which adds a quietly nerdy affection to anyone who chooses the name.
