What physical process must owners manage twice annually regarding the West Siberian Laika's coat?

Answer

Blowing their undercoat heavily

The West Siberian Laika possesses a thick, dense double coat engineered for superior insulation against extreme cold and deep snow. This coat structure necessitates specific seasonal management. Crucially, the breed undergoes a process where they 'blow' their undercoat heavily, shedding massive amounts of the soft, insulating fur twice every year. During these periods, brushing must be thorough to effectively remove the dead undercoat and prevent potential matting, although moderate brushing suffices during the rest of the year.
