The Samoyed is known for its smiling expression and was traditionally used to herd reindeer.
This white, thick-coated spitz breed developed in northern Siberia among Samoyedic peoples, including the Nenets. Its ancestors were related to the Nenets Herding Laika, a working dog used for reindeer herding, hunting, protection, and pulling sleds. The dogs also lived closely with people, helping them endure Arctic conditions.
The breed’s characteristic “smile” comes from its alert, happy expression and slightly upturned mouth corners. This appearance has inspired nicknames such as “Sammie smile” and “smiley dog.” The expression is not a deliberate grin in the human sense, but a result of the breed’s facial structure and friendly temperament.
Samoyeds are usually white, cream, or white-and-biscuit, with a dense double coat that helps insulate them from cold. They later became valued in polar expeditions, including the 1893–1896 Fram expedition. Despite their gentle reputation, they remain energetic working dogs that need activity and companionship.
