What specific component of the Pembroke Welsh Corgi's double coat provides insulation?

Answer

Undercoat

The Pembroke Welsh Corgi possesses a protective double coat adapted for the variable weather conditions in Wales. This coat system consists of two distinct layers. The outer coat is described as being straight, medium in texture, and primarily functions to shed water and dirt via longer guard hairs. In contrast, the component responsible for insulation against the cold is the undercoat, which is characterized as being thick and soft. This undercoat sheds heavily during certain times of the year, leading to significant amounts of loose hair requiring management.
