Inside the Minds of Puppies: How Do They Develop Their Thinking Skills?
A five-year Duke study tracking more than 100 service-dog puppies has produced one of the most detailed looks ever at how young dogs develop thinking and communication skills. Led by Ph.D. researcher Hannah Salomons, the work demonstrates that most cognitive abilities emerge early, albeit on different timelines, and that puppies are biologically primed to understand human gestures--a trait not observed in wolf pups. The findings offer new insights into how dogs evolved to cooperate with humans and could help service-dog organizations predict which puppies are most likely to succeed early on. With training costs exceeding tens of thousands of dollars per dog, this research has the potential to enhance placement accuracy and expand access to life-changing service animals.
