If you own a dog and have come home to your pup smelling like another dog, chances are your furry friend will give you the cold shoulder out of jealousy. Think dogs can’t get jealous? Think again. A newstudyfound that dogs don’t just get jealous when they are around a rival for their favorite person’s attention, they can actually dream up scenarios that make them feel jealousy even if it’s not happening in front of them. The research is significant because jealousy as an emotion is linked to being “self-aware,” something most people think distinguishes humans from animals. It might be time to stop joking around about your dog “thinking” he’s human because, as most owners already know, dogs might actually be smarter than we are -- and science is finally catching on.
