If you’re a dog owner, it’s a safe bet that you feel your pet is tuned into your emotions. Now, science has proved that this really is the case. However, it’s the way that canines sense human emotions that’s rather astonishing...

When you’re happy and you know it, your dog does too – joyfully adding to the moment with wags, barks and leaps of delight. Likewise, when you’re feeling down, your dog will quietly sit by your side with empathetically sad eyes to show their support.
Dog people know that their pets are tuned into their emotions – and now science has proved it. And it has a lot to do with a canine’s amazing sense of smell. A new study by a team at the University of Naples in Italy – reported in New Scientist – has found that not only can dogs interpret visual and auditory cues that tell them what humans are feeling, they can actually smell human emotions and adopt them as their own. Essentially – if you feel happy or sad – your dog does too.
DID YOU KNOW?
Biagio D'Aniello, a researcher on the study, commented: “The role of the olfactory system has been largely underestimated, maybe because our own species is more focused on the visual system."
And, while it’s common knowledge that dogs have a superior sense of smell, the idea that they can scent out the emotional states of others means they have access to a whole other world of social information. It could be that this heightened sense is what makes our pets seem so intuitive.
DID YOU KNOW?
For the study, D'Aniello and colleagues had human volunteers watch videos that elicited strong emotional responses, and then collected samples of their sweat. The sweat samples – and odours that accompany them – were then presented to a group of dogs, while researchers monitored the animals' behaviours and heart rates. Incredibly, the dogs adopted behaviours and stress responses consistent with the emotions that were experienced by the human volunteers.
The pets' reaction was most acute when they smelled sweat samples associated with human fear responses. Dogs acted fearful themselves, seeking out more reassurance from their owners while making less contact with strangers.
This new research adds to a rich set of data demonstrating that dogs have a high level of emotional intelligence, especially when it comes to understanding their human companions. Scientists believe that this highly developed canine intuition is most likely due to the domestication of dogs over thousands of years.
DID YOU KNOW?
So, while dogs may have been our close companions for around 30,000 years, it seems that science has only uncovered the tip of the iceberg when it comes to really understanding what makes the canine-human relationship so special. What on earth will they discover next?

Do you talk to your dog?
Research reveals that dogs can understand human communication in ways no other species can. Yet, only 1 in 5 dog owners think that bonding with their dog includes actually chatting with them. Are humans missing a trick?
