The oldest dog remains ever found in the Americas are 10,150 years old and prove canines were with humans when the land was first colonised 6,000 years before.
Analysis of a chunk of dog femur, which was found in southern Alaska, reveals the animal was a descendant of Siberian dogs.
Scientists believe these ancient dogs accompanied the first humans to the Americas at the end of the last Ice Age when glaciers were in retreat.
The finding backs up the theory that people migrated into what is today Alaska from eastern Russia by following a route along the coast as the Bering Strait thawed.
