2. When it looks into your eyes
Perhaps the strongest gesture in the list. When a dog looks at you voluntarily in the eyes it is a gesture of clamorous affection: “When a dog looks you straight in the eye, it’s like he wants to give you a hug. It is our embrace between humans.”
Several studies have shown that when your dog stares at you while you are playing together or cuddling him, oxytocin is released into your body, the same hormone that helps mothers to be affectionate with their children after birth. The affection gene in a nutshell.
