Photo: Dogs Can Feel Envy, Study Suggests



Dogs can feel envy, a December 2008 study suggests.

In experiments with 43 dogs, an Austrian research team showed that dogs reacted to inequity. One dog watched another dog receive a reward for a trick. When the watcher dog performed the same trick and was not rewarded, that dog refused to do the trick again.
