The domestic dog was present 9,500 YBP on what is now Zhokhov Island, arctic northeastern Siberia. The archaeological discoveries at the Zhokhov site includes the remains of dog harness straps similar to those used by the modern Inuit, the bone remains of polar bears and reindeer which suggests a wide hunting range and the transport of large body parts back to the site, and tools made from obsidian transported from 1,500 kilometres away. These findings suggest long-distance transport through the use of sled dogs.
