Dogs are even more like us than we thought

In a new study, scientists tested 54 dogs that each watched their owners struggle to retrieve a roll of tape from a container. The dogs were divided into three groups: Helper, non-helper, and control.

In the helper group, the owner requested help from another person who held the container. In the non-helper group, the owner asked for help from a person who turned their back on them. In the control group, the additional person turned his or her back without being asked for help. In all experiments, a third “neutral” person sat in the room.

After the first round of experiments, the neutral person and the helper or non-helper both offered treats to the dog.

In the non-helper group, canines most frequently favored the neutral person’s treat, shunning the non-helper. However, in the helper group, the dogs did not favor either the neutral or helper’s treat. Scientists have previously observed similar results in human infants and tufted capuchin monkeys.
