Inuit sled dogs and other Alaskan breeds are the only dogs with American origins, according to new research. Although the original canine stock has been traced to Asia, there is evidence of dogs in the Americas dating to 10,000 years ago, before transoceanic travel brought Europeans and their dogs to the continent. "Nobody knows exactly what happened," researcher Peter Savolainen said. "Most probably migrated together with the humans that entered America from Asia via the Bering Strait. These humans became today's Indians and Inuits." The canines became Inuit sled dogs, the Greenland dog and the Eskimo dog, according to the research.
