A new test conducted by researchers at the Max Planck Institute for the Science of Human History and the Department for General Psychology and Cognitive Neuroscience (Institute of Psychology) at Friedrich Schiller University of Jena illustrated that dogs have a mental picture or an expectation of what they will find at the end of a scent trail based on the scent of the object.
The test was conducted on dogs (police and search and rescue dogs) trained to follow a scent as well as pets not trained to follow a scent. Both groups showed surprise when the object that they found was not the one used to lay the scent trail.
Although this test was not intended to illustrate the mind of the dog, this is further evidence of the mental abilities of dogs showing that they anticipate what will happen in the future based on their surroundings. Many dog owners have seen this behavior in relation to other events. An example is the dog who can anticipate the arrival of a family member when that person comes home at about the same time every day.
It is exciting to anticipate what future studies will show us about the mind of animals.
