Snowy

Snowy, Tintin's favorite dog.

Throughout the series, Snowy is Tintin's sidekick and companion on journeys.[6] Along with Tintin he is the only character to appear in all of the albums.[4] In Tintin in the Land of the Soviets, where he is introduced, Snowy acts as the source of humor.[2] Throughout the first eight stories Snowy is the series' co-star;[3] he is able to understand human language and is portrayed with speech bubbles. His comments provide comedy or urge his master to use caution or fear. In the early albums he takes an interest in mechanics, geography, and in Tintin in the Congo makes biblical references.[7] He also takes on a more traditional role of a dog and is able to sniff, track, chase, and bite.
