A new study has shown that almost two thirds of modern dog breeds carry traces of wolf DNA, which could influence their size, ...

Every household dog, from a towering Great Dane to a trembling toy breed, traces back to wild wolves. New genetic work shows that this ancestry is not just a distant story but a living imprint in ...

Those tiny, fluffy dogs walking down the street may look cute but beware — they probably have some wolf in them. That is the discovery announced on Monday by U.S. scientists, who were surprised to ...

Their new study, published in PNAS, examined 2,693 genomes from modern and ancient dogs and wolves. It shows that 64% of dog breeds have detectable traces of wolf ancestry, remnants of ancient ...

Many dog owners may not be surprised to learn that most dogs still carry some wolf DNA in their genomes. Domestication has changed dogs dramatically from their wolf ancestors, but most do still have ...
