Snow and water damage fur coats, not the hair but the hidden skin underneath. When that leather gets wet it shrinks, dries out, and loses its oils. Once that happens seams tear and fur starts shedding early. Fur is cleaned dry, traditionally with corn husk and sawdust or today with fur safe dry solvents.
