What does Leo mean?
/ˈliːoʊ/2 syllablesOrigin: Latin

Leo comes directly from the Latin leo, meaning "lion." It's also the name of a zodiac constellation and sign, which has helped keep the name closely tied to images of strength and courage across many cultures.

Leo has a bold, confident sound that suits a pet with real presence, whether that shows up as a commanding bark or a regal, unbothered stare. It's a small word with an outsized personality.
