Do dogs have morals?

Living with people has changed dog behavior

Scientists claim that living with humans has changed dog behavior, essentially teaching them morals.

"They say the fact that dogs' play rarely escalates into a fight shows the animals abide by social rules.

During one study, dogs which held up a paw were rewarded with a food treat.

When a lone dog was asked to raise its paw but received no treat, the researchers found it begged for up to 30 minutes.

But when they tested two dogs together but rewarded only one, the dog which missed out soon stopped playing the game."
