The domestic dog is one of the world’s most successful species by any ecological measure, so discussing their conservation may seem odd. However, despite the widespread distribution and huge numbers of dogs, there are genetic populations of them at risk. One such group is the Greenland Sled Dog, which lives in human communities north of the Arctic circle on both the east and west coasts of Greenland.
The ancestors of the Greenland Sled Dogs were first brought to the region nearly a thousand years ago by the Thule people, who are the ancestors of the modern Inuit. Genetic studies published in 2015 established that these dogs are not a separate breed from the Canadian Eskimo Dog, but that the population is distinct from Siberian Huskies, Alaskan Huskies and Malamutes.
