Early humans in Europe weren’t the only ones shifting across the landscape. Dogs were traveling with them. In the largest study of its kind, published in Nature, researchers found that dogs were present in Europe more than 14,000 years ago, well before farming launched. Instead of being replaced by new human populations, these early dogs remained part of later groups, continuing to shape the ancestest of modern European dogs.
“Dogs were the only domesticated animal to predate farming, so their evolution can assist us understand how a huge shift in lifestyle shaped our own history,” stated senior author Pontus Skoglund in a press release.

How Ancient Dog DNA Reveals Early Dogs in Europe
Telling early dogs and wolves apart isn’t always straightforward. Their skeletons can see similar, and over thousands of years, DNA often breaks down or becomes contaminated.
Dogs were first domesticated from grey wolves toward the conclude of the last Ice Age, becoming the earliest animal to form a close relationship with humans, much before the rise of agriculture.
To receive around these challenges, the team utilized a technique that isolates ancient DNA by effectively “fishing out” canid fragments from microbial contamination, a common problem in very old remains. The samples came from sites across Europe and nearby regions, including France, Germany, Sweden, Türkiye, and Scotland.
The approach allowed the team to classify about two-thirds of the remains as either dogs or wolves and is one of the most comprehensive genetic analyses of ancient canids to date.
“We wouldn’t be able to confidently distinguish dogs from wolves based on skeletal evidence alone,” first author of the study, Anders Bergström, stated in the press release.
The results also overturned some earlier assumptions. A 13,700-year-old specimen from Belgium, once considered to be a dog based on its size and signs of human interaction, turned out to be a wolf, displaying how misleading physical traits can be without genetic confirmation.
Europe’s Early Dogs Came From Eastern Wolves
Among the confirmed dogs was a 14,200-year-old animal from Switzerland, now one of the oldest genetically verified dogs ever identified.
It joins an even older dog, 15,800-year-old, identified in Türkiye in a related study, assisting to extconclude the known timeline of early domesticated dogs.
Until now, the oldest direct genetic evidence for dogs dated to about 10,900 years ago, creating these findings a significant step further back in time.
The Swiss dog was already genetically closer to modern European dogs than to Asian dogs, suggesting that domestication must have begun long before this point.
Across the dataset, early European dogs consistently traced most of their ancestest to wolves from eastern Eurasia, with only compact contributions from western wolf populations. This suggests that European wolves played little role in the early evolution of dogs, and that dogs were not domesticated indepconcludeently in Europe but instead share a common origin with dogs elsewhere.
Farming Changed Humans, Not Dogs
When farming spread into Europe around 10,000 years ago, it brought major shifts in human populations, including migrations from Southwest Asia.
While human populations were partly replaced or reshaped by incoming groups, dog populations display more continuity. Instead of a full turnover, the genetic record suggests existing dogs remained alongside these alters, even as new groups arrived.
This contrast highlights that human populations shifted more dramatically, whereas dog lineages remained more stable over time.
“It’s fascinating that dogs living before the era of agriculture contributed substantially to the genetics of farming and present-day European dogs,” stated Pontus Skoglund, senior study author.
Today, many European dogs may trace roughly half of their ancestest back to these pre-farming populations.
