Tintin, the title character of a comic series by Belgian artist Herge, is joined in his adventures by his dog Snowy. In the original series, Snowy is known as Milou, after a pet name the artist had for his first girlfriend.
Snowy is a white fox terrier, and Herge has stated that he chose this particular breed due to its popularity at the time of creating the comic. Additionally, the artist found inspiration at a cafe he frequented; the cafe landlord was the proud owner of a fox terrier.
Initially in the series, Snowy and Tintin can directly communicate. Over time, though, other main characters are added and the terrier's speaking role is omitted in favor of a non-verbal comedic one.
