Study Shows Dogs May Exhibit Envy

The first video demonstrates reward inequity condition. The Border Collie does not get rewarded for giving the paw whereas her partner - the mix - receives a piece of bread. She worked only a few times, when she did not get a reward. The second video shows the same Border Collie in the asocial control. She is asked to give the paw, but does not get rewarded for doing it. In this condition she works a total of 30 times, then the experimenter stopped asking her. Video courtesy Friederike Range
