Greenland Dog

The Greenland Dog (Greenlandic: Kalaallit Qimmiat, Danish: Grønlandshunden) is a large breed of husky-type dog kept as a sled dog. They were brought from Siberia to North America by the Thule people 1,000 years ago, along with the Canadian Eskimo Dog that is genetically identical. The Greenland Dog (Greenlandic: Kalaallit Qimmiat, Danish: Grønlandshunden) is a large breed of husky-type dog kept as a sled dog. They were brought from Siberia to North America by the Thule people 1,000 years ago, along with the Canadian Eskimo Dog that is genetically identical. The first dogs arrived in the Americas 12,000 years ago. However, people and their dogs did not settle in the Arctic until the Paleo-Eskimo people 4,500 years ago and then the Thule people 1,000 years ago, both originating from Siberia. Dogs first appeared in Greenland around 4,000 years ago. The Inuit dogs from Canada (Canadian Eskimo Dog) and Greenland (Greenland Dog) descended from dogs associated with Thule people, who relied on them for transportation from Siberia. In 2015, a study using a number of genetic markers indicated that these were both the same dog and should not be treated as separate breeds, that they maintain an indigenous heritage that predates colonization and the timing corresponds with the arrival of the Thule people, and that they were distinct from Siberian Huskies, Alaskan Huskies and Malamutes. The maternal mitochondrial DNA sequences of the Inuit dogs were classified as haplotype A31 that indicates a common female ancestor, and this haplotype could not be found in other modern dogs but the nearest match was with a 1,000 year–old dog from Florida. In 1975, a study was made of ancient canid remains dated to the Late Pleistocene and early Holocene that had been uncovered by miners decades earlier around Fairbanks, Alaska. These were identified as Canis lupus and described as 'short-faced wolves.' The collection was separated into those specimens that looked more wolf-like (i.e. the Beringian wolf), and those that looked more dog-like and in comparison to the skulls of Eskimo dogs from both Greenland and Siberia thought to be their forerunners. Nearly all dog breed's genetic closeness to the gray wolf is due to admixture. However, several Arctic dog breeds show a genetic closeness with the now-extinct Taimyr wolf of North Asia due to admixture. These breeds are associated with high latitudes - the Siberian Husky and Greenland Dog that are also associated with Arctic human populations, and to a lesser extent the Shar Pei and Finnish Spitz. An admixture graph of the Greenland dog indicates a best-fit of 3.5% shared material, however an ancestry proportion ranging between 1.4% and 27.3% is consistent with the data. This indicates admixture between the Taymyr wolf population and the ancestral dog population of these 4 high-latitude breeds. This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment. It also indicates the ancestry of present-day dog breeds descends from more than one region. The Greenland Dog is a powerful, heavy-built dog. It has a broad, wedge-shaped head, slightly tilted eyes and small, triangular ears covered with thick fur that prevents frostbite. It has strong, muscular, short-haired legs. The tail is usually rolled along/across its back. When it lies down and curls up to rest, the tail often covers the nose. Its coat is of medium length and consists of two layers. The inner layer consists of short wool-like fur, the outer layer of longer, coarser, water-repellent fur.
