Dogs may make social judgements about people based on how those people treat their owners. A study out of Japan had dog owners asking two people for help opening a container. There were three possible outcomes. A person reacting negatively by refusing and turning away, a person remaining neutral and a person helping.

Dogs were much much less likely to accept food from the people who had refused to help their owners, and much more likely to accept food from those who had been neutral or who had helped.
