What specialized function defines the Yakutian Laika predominantly among its Laika cousins?

Functioning predominantly as a sled dog

Although the general 'Laika' category covers dogs with varied functional backgrounds, the Yakutian Laika developed a specific niche due to the inland conditions of its environment. While it retains rudimentary abilities in hunting and herding reindeer, its role is overwhelmingly specialized as a sled dog responsible for hauling freight. This specialization in sustained work in harsh inland conditions suggests that its evolutionary trajectory diverged from cousins that might have been bred more for maritime roles or different types of terrain management. The consistent need to pull significant loads over vast distances throughout the 1800s cemented this specialized classification as a durable, purpose-bred working animal.
