Louie

Louie is a French form of Ludwig, from Old High German Hlodwig meaning "famous warrior" or "renowned in battle" — composed of elements meaning fame and combat. It was the name of eighteen kings of France, which ought to make it grand and ceremonial. And yet Louie, with its casual French spelling, manages to feel relaxed and friendly instead, all that royal history worn lightly.

Louie holds the #46 spot among US pet names, with over 1,600 companions sharing it. The name has an easy, almost musical quality — three letters that feel both jaunty and substantial. It tends to suit companions with a certain rakish charm: sociable, slightly theatrical in their affection, the kind of animal who is always the center of attention without any apparent effort. Louie has been rising in pet naming as owners seek names with European flair and a casual elegance.
