Madeline is the little girl who lived in a house in Paris, covered in vines, in twelve little girls in two straight lines. Ludwig Bemelmans' picture book character has been in continuous print since 1939, and her name has never quite lost the association with that specific combination of Parisian settings, boarding school adventures, and fearless small-creature energy.
The Bemelmans Reference
For owners who grew up with Madeline books or the 1990s animated series, naming a pet Madeline is a direct callback to a beloved character. The book's Madeline is small but undeterred, which makes the name work particularly well on small female pets who are not intimidated by anything. French Bulldogs and Chihuahuas appear with this name at above-average rates — both small, both apparently aware of their own importance.
Human Parallel
Madeline and Madeleine rank consistently in U.S. baby name data. The human name page traces it to Mary Magdalene — the name carries significant religious and literary history before Bemelmans ever picked it up. That depth gives the pet name more resonance than it might appear to have.
Counter-Read
Madeline is a lot of name to say quickly at a dog park. The natural nickname is Maddie, which many owners default to anyway — raising the question of whether Madeline is the official version of a Maddie or a genuinely used full name. Compare Maddie directly if the shorter form is the real choice.
