In the second experiment, the dogs were given a squirt of oxytocin up their noses before interacting with their owner and two strangers. The female dogs – but not the males – who were given ...

The dog and cat study showed that neither species consistently increased oxytocin in humans. Only 30 percent of participants had an increase in oxytocin after playing with an animal.

No effect was recorded in male dogs. Kikusui hypothesizes that the nasal spray may have exclusively affected female dogs because oxytocin plays a more significant role in female reproduction.
