In human-dog interactions, eye contact is a key element in initiating and maintaining the relationship.
Scientists recently discovered another key reason for eye contact with dogs: bonding.
Eye contact increases a brain chemical called oxytocin, the same chemical present in the bond between parents and children. Scientists speculate that this chemical is at least partly responsible for how dogs were domesticated in the first place.
With your own pet, as a human owner, you should always be the dominant figure or the “leader of the pack.” A dog that believes that he is the “master” or leader will be a dog that will not obey orders and may even become aggressive.
There is a difference between maintaining eye contact or staring, and even your own pet may feel uncomfortable or threatened. If a dog is uncomfortable with eye contact, he will turn away or look away.
