Those big brown eyes gaze at you, deeply. Your heart leaps. You caress, murmuring sweet nothings. And as those big browns remain fixed on you, the tail wags.
Devoted dog. Besotted owner. That continuous loop of loving reinforcement may begin with the dog’s gaze, according to a new report in Science.
Japanese researchers found that dogs who trained a long gaze on their owners had elevated levels of oxytocin, a hormone produced in the brain that is associated with nurturing and attachment, similar to the feel-good feedback that bolsters bonding between parent and child. After receiving those long gazes, the owners’ levels of oxytocin increased, too.
The dog’s gaze cues connection and response in the owner, who will reward the dog by gazing, talking and touching, all of which helps solder the two, the researchers said. They suggest that dogs became domesticated in part by adapting to a primary human means of contact: eye-to-eye communication.
And when researchers gave dogs extra oxytocin through a nasal spray, the female dogs (though not the males) gazed at their owners even longer, which in turn boosted the owners’ oxytocin levels.
