Wolves and dogs both have a sense of fairness
From Smithsonian.com:
Give a kid a cookie and her friend a carrot—and you’ll likely hear some complaining. But this concept of inequity is a trait researcher long thought unique to humans.
But in 2003, scientists found that capuchin monkeys could recognize such inequity, and just five years later they found that domesticated dogs could, too. Now, as Matt McGrath at the BBC reports, a new study suggests that wolves also exhibit this ability—and that it’s unlikely it’s a byproduct of domestication.
