Why your pup looks at you (it’s not just to beg for a treat)

French bulldogLast Christmas, as I was patting my sister’s little female French bulldog, I found myself thinking how relaxing it felt – well, apart from the slightly itchy eyes. At some point, the dog tilted her head towards me, and we embarked on some sort of staring contest. As the mutual gaze prolonged, I started wondering: What could be going through her mind? Was she thinking about something? Why was she keeping her big but oh-so-cute bulgy eyes fixed on mine?

When compared with wolves, dogs’ closest relatives, and great apes, humans’ closest relatives, dogs appear much more skilled at recognizing and using social cues such as gesture or gaze direction to cooperatively interact with humans, even already as puppies.

But it’s not just that. Why is it that we feel genuinely attached to dogs? What are the biological mechanisms underlying the friendship and love we come to develop towards them? Continue reading


Oxytocin and human behavior – or how a hormone can (or can’t) influence the distance between man and woman upon a first encounter.

Rather intrigued, I checked out the original study, which was published on November 14 in the Journal of Neuroscience. Continue reading
