Researchers at Cornell University have found that there is a neurological link between a dog’s sense of smell and their vision. This study shows that a dog perceives his environment using both vision and scent. This is the first time that scientists have found a neurological connection of this nature in any animal.

In addition, scientists have found that dogs have connections between areas in the brain that process memory and emotion which are similar to humans but that they also have connections between the spinal cord and the occipital lobe which are not found in humans.

This finding explains why blind dogs are able to function, being able to play fetch and navigate their surroundings much better than people with similar blindness. That is comforting for people who own dogs who are blind or have gone blind.

Author’s Note: Although blind dogs can find their way around better than people, it is still a good idea to not move furniture around. If you have to move or add furniture, you can put a unique gentle scent on the corners of the furniture at the dog’s level to help the dog locate and identify the new or moved object.

We also have to think about how the relationship between scent and vision affects dogs in terms of training and their reaction to the environment, taking into consideration personality traits such as friendliness, fear, aggression etc. While we know that many of the personality traits of dogs are inherited, is it possible that these findings might explain further exactly how and what is inherited. Many people do not realize how complex dogs and perhaps other animals are.
