Dogs sense injustice when other dogs get treats for tricks and they don’t.
Have you ever suspected your dog of getting jealous and keeping a “treat score”? Friederike Range, a neurobiologist at the University of Vienna, proved you right this week. Range, who herself has a dog she considers the ‘jealous type,’ found that dogs that didn’t get a treat for shaking hands when another dog did, would get annoyed and eventually stop doing the trick. Dogs can get huffy if they’re not rewarded for their efforts – and rightfully so! “We have a dog at home. And I know how jealous she is of different people and situations,” Range told The New York Times. This research backs up what scientists have already documented in monkeys. Next up for Range: cheating other animals out of treats to see how they react.
