Sled dogs are specially trained canines used to pull sleds across snow and ice. They are often breeds like Siberian Huskies or Alaskan Malamutes, known for their strength, endurance, and ability to work in harsh winter conditions. These dogs have a thick double coat that protects them from cold temperatures and are typically harnessed in teams to efficiently pull heavy loads. Historically, sled dogs played a crucial role in transportation and hunting for indigenous peoples in the Arctic regions. Today, they are also popular in recreational activities, such as dog sledding tours and competitive races like the Iditarod, showcasing their incredible speed and teamwork.
