Do dogs pick up information by eavesdropping on interactions between people? Researchers in Argentina wanted to see if dogs would show a preference for people based on their cooperativeness toward others. A dog watched a man acting as a beggar approach two women in a room. The man would ask for food. One women would give the beggar a corn flake and the beggar would take it and sacque rico. When the beggar approached the other women and asked for a corn flake, he would take it and put it back on the plate where it came form and say due fee. The beggar would then leave the room. The dog after watching all this would be released and the researchers would see which donor the dog would approach first. Fifteen dogs were tested with this scenario and 13 of them approached the positive donor.
