What technology and economic shift initiated the severe demographic crisis for the Yakutian Laika population starting around the 1950s?

Arrival of snowmobile technology coupled with decreased fur hunting and fishing

The near-extinction level crisis faced by the Yakutian Laika between the 1950s and the 1990s was directly attributable to major socioeconomic and technological advancements in the Siberian North. The primary factor was the arrival and widespread adoption of snowmobile technology, which effectively rendered the dog teams obsolete for many essential hauling tasks. Compounding this was a concurrent reduction in fur hunting and local fishing—the economic activities that previously supported the large kennels required to maintain the dog populations. This dual pressure significantly lowered the need for these working animals, causing the population to plummet near extinction by 1998.
