Karlsson of the University of Massachusetts Chan Medical School and their colleagues surveyed 18,385 dog owners—roughly half of whom had purebred dogs and half had mixed-breed dogs—about their pets’ behavioral traits and also sequenced the DNA of 2,155 dogs. Their analysis showed that breed wasn’t a reliable predictor of behavior for individual dogs and that it explained just 9% of the variation seen. “A dog’s personality and behavior are shaped by many genes as well as their life experiences,” Karlsson says in a press statement. Behavioral traits are the result of thousands of years of adaptation, whereas modern dog breeds that embody particular physical traits came about less than 160 years ago. Every dog owner knows that their pet is a unique individual—now they’ve got some science to back it up.
