Dogs act jealously even when they don't see their rival

Past surveys have shown that more than 80% of dog owners report observing jealous behaviors from their dogs—vocalizations, agitated behavior, pulling on a leash—when they give attention to other dogs. New research published in the journal Psychological Science supports these observations and finds that dogs also exhibit jealous behaviors when they merely imagine that their owner is interacting with a potential rival, in this case, a highly realistic artificial dog.
