How do sleddogs help humans survive?

Sled dogs have historically played a crucial role in helping humans survive in harsh, cold environments, particularly in Arctic regions. They are used for transportation, enabling people to travel long distances over snow and ice, which is essential for hunting, gathering resources, and accessing remote areas. Additionally, sled dogs can assist in carrying heavy loads, making it possible to transport supplies and equipment necessary for survival. Their keen senses and ability to navigate difficult terrains also enhance human safety in extreme conditions.
