What two components comprise the thick, dense double coat essential for the Yakutian Laika's survival?

Answer

A soft undercoat and a longer, straight outer coat that is somewhat harsh

The Yakutian Laika possesses a classic double coat structure necessary for thriving in the brutal Siberian climate. This coat consists of two distinct layers. The undercoat is described as soft, providing essential insulation against the cold. Layered over this is the outer coat, which is longer and straight, possessing a texture that is somewhat harsh to the touch. This combination ensures both warmth retention and protection from the elements.
