"Serpell is most excited about new studies on oxytocin and dog ownership. Oxytocin is the most important social-bonding hormone, present notably between mother and child but also in just about any interaction involving pair bonding, social affiliation, and trust. More specifically, it’s involved with the gaze between infants and mothers. Researchers at Azabu University in Japan found last year that the dog’s gaze at its owner increases the owner’s oxytocin level."
I often gaze into the eyes of dogs and I can confirm that it puts me at ease.
