Scientists have conducted comprehensive research and have determined that when a person looks at a pet dog, the hormone oxytocin is produced in his or her body. Apparently, that’s why dogs love to look at their master with their gentle eyes, when they want to get something. By the way, the same hormone in the body is produced when a person looks at a small child.
This oxytocin is the sole culprit why dogs “understand” us so profoundly. Many dog owners can confirm that whenever they are sad, worried or anxious their dog starts to behave differently, as if they can read our thoughts and feelings.
