The imagination of the dog owner
The study “Canine Behaviour and Cognition” investigated how dog owners interpreted their dogs’ expression when they believed the dog had stolen and eaten a treat. In a series of tests, the owners sometimes received accurate and sometimes false information about whether their dog had stolen the treat. The study showed that there is no link between the interpretations of the owners and whether or not their dog had stolen the treat.
When the owners were told that their dog had misbehaved, they saw a guilty expression, even when the dog done nothing wrong. Where there was any change in the dog’s expression, this could be explained as a reflection of human emotions. If the owner thought the dog had misbehaved and told the dog off, some dogs showed an admonished look. This was incorrectly interpreted by the owners as an admission of guilt. The researchers conclude that the so-called guilty look is a response to the behaviour of humans and bares no relation to the actions of the dog or a sense of having broken any rules.
