Do dogs get jealous? Most dog owners would say yes, but until now, no scientist has. That changed when researchers headed down to the store and picked up a robotic dog and a plastic jack-o’-lantern, and knocked on the doors of 36 dog owners, asking for a moment of their time.
It was a fairly simple study, which is best when you’re studying dogs. Scientists from the University of California San Diego, led by psychologist Christine Harris, set up a camera, set out the two items — again, robotic dog and a plastic jack-o’-lantern — and asked each dog’s owner, in front of the dog, to interact with each.
