Snowy (French: Milou [milu][1]) is a fictional character in The Adventures of Tintin, the comics series by Belgian cartoonist Hergé.

Snowy made his debut on 10 January 1929 in the first installment of Tintin in the Land of the Soviets, which was serialised in Le Petit Vingtième until May 1930.

Hergé diminished Snowy's speaking role after the introduction of Captain Haddock in the ninth story, The Crab with the Golden Claws.

[4] As of 1 January 2025, Snowy and other characters appearing in the 1929 The Adventures of Tintin comic strips have entered the public domain in the United States,[5] but not in Hergé's native Belgium, which will be in 2054.

Snowy's original French name Milou—an abbreviation of Marie-Louise—is borrowed from the nickname of Hergé's first girlfriend, Marie-Louise Van Cutsem.

The name Snowy was chosen for English-language translations not only because of the dog's colour,[3] but also because it is a five-letter word that fits in the speech balloons.

Before Haddock's appearance, Snowy was the source of dry and cynical side-commentary, which balanced out Tintin's constantly positive, optimistic perspective.

[11] Snowy indulges in rowdy behaviour chasing the Siamese cat at Marlinspike Hall until the two become friends at the end of The Calculus Affair.

[7] Among the anthropomorphic cast of Bryan Talbot's graphic novel Grandville, there is a white Wire Fox Terrier named "Snowy Milou".

[15] Early in the development process, when the motion-capture was being filmed in-studio, the production team considered casting a dog as Snowy.
