It was just a look from a young dog, but somehow it made me feel warm and loved. When a child gazes at his or her caretaker it is interpreted as either an expression of affection or a request for some sort of interaction. The link to dogs comes from the fact that a survey conducted by the American Animal Hospital Association reports that 75% of dog owners consider their pets to be pretty much the equivalent of young children. Most pet owners seem to treat and respond to the signals that dogs give out in much the same way that they would respond to signals from a child. The dogs that were well-bonded to their owners tended to gaze at them a lot more, and the data confirmed that the more they gazed at their owners the higher the oxytocin levels rose, suggesting that their human caretaker's feelings of well-being, and of being loved, were also rising. So the bottom line seems to be that dogs do have a "look of love" which can tug at your heartstrings and make you feel better—but only if you already have an affectionate bond with that dog. The oxytocin concentration was obtained in the human participants' urine, which was collected before and after each test session. The findings were interesting, it had been expected that the oxytocin level in the human would rise based on the dog and owner making visual contact, and it did, but only for the group which had the stronger bond.
