How is the dense double coat of the Yakutian Laika structured for Arctic survival?

Answer

It features a soft, thick undercoat for thermal insulation and a harsh, straight outer coat

The Yakutian Laika’s coat is a perfect adaptation to temperatures that can drop drastically below freezing in its native environment. This insulation system relies on a well-developed double coat structure. The inner layer, or undercoat, is specifically characterized as being soft and thick; its primary function is to create an essential thermal barrier, trapping body heat close to the skin. Conversely, the outer coat provides protection from external elements like snow and moisture. This outer layer is typically described as being somewhat harsh and straight, offering durability that complements the insulating properties of the dense undercoat.
