The Alaskan Malamute is a large breed of dog that was originally bred for their strength and endurance to haul heavy freight as a sled dog and hound. They are similar to other arctic dogs like husky, and spitz breeds such as the Greenland Dog, Canadian Eskimo Dog, the Siberian Husky, and the Samoyed. Although it is believed that the first dogs arrived in the Americas 12,000 years ago, people and their dogs did not settle in the Arctic until the Paleo-Eskimo people 4,500 years ago, followed by the Thule people 1,000 years ago, with both originating from Siberia. Malamutes were thought to be bred by the Malemiut Inupiaq people of Alaska's Norton Sound region. In 2015, a study using several genetic markers indicated that the Malamute, the Siberian Husky, and the Alaskan husky share a close genetic relationship between each other and were related to Chukotka sled dogs from Siberia. They were separate from the two Inuit dogs, the Canadian Eskimo Dog and the Greenland Dog.
