  1. Dogs, Humans Bond Through Eye Contact

    All pups learn this trick. Human babies and mothers bond by gazing at one another’s faces, and that same reaction works when canines stare into our eyes, according to new research. Scientists found that when pups and owners exchange looks, “love hormone” oxytocin levels rise in both, proving there’s a chemical feedback link. Dogs don’t gaze at one another, so it’s a trick reserved for humans — and it may shed light on how once-fearsome wolves evolved into man’s best friends.
