Jealousy in dogs
Harris and Prouvost, PLoS ONE 9(7), 2014, e94597. Thirty-six dogs tested at home in three counterbalanced one-minute within-subject conditions: owner affectionate toward a realistic stuffed dog, toward a pumpkin-shaped pail, or reading a pop-up book aloud. Dogs pushed or touched owner and object more, and tried to get between them more often, in the stuffed-dog condition. About 86 percent sniffed the stuffed dog's rear end; about 14 percent did not sniff and showed few jealous behaviours. The authors argue jealousy has a primordial form shared by human infants and at least one other social species.
