Another scientific study showing that dogs and people have some thought processes in common.

The sense of fair play is an important human trait, but new research suggests that it’s a key behaviour for dogs and wolves as well.

In tests, if one animal was given a more substantial reward when performing a task, the other one downed tools completely.

It had been felt that this aversion to unfairness was something that dogs had learned from humans.

But the tests with wolves suggest that this predates domestication of dogs.
