Most fascinatingly, these genetic differences are in the area of the genome associated with hypersociability in people with a genetic condition called Williams-Beuren syndrome. Although people with this syndrome experience negative health effects, they also tend to be very open, engaging and sociable.
Not all dogs fall into this hypersocial category — but even those that don't are unusually accepting of unfamiliar people and dogs.
