Do Dogs Understand Fairness?
In this video excerpt from NOVA scienceNOW, learn how scientists are studying basic moral behavior in animals. Correspondent David Pogue, New York Times technology columnist, visits Friederike Range's Clever Dog Lab to find out whether dogs have a sense of fairness. If two dogs are asked to do a trick and only one of them gets rewarded, the unrewarded dog soon stops cooperating.

This video is available in both English and Spanish audio, along with corresponding closed captions.
