In a recent study, it was discovered that dogs can not only smell rising stress levels in humans but that it can also affect their decisions and overall mood. Noticing a person in distress negatively impacts their optimism, making it more likely for canines to make pessimistic choices.
Research shows smelling stress in humans can affect decision-making and mood in dogs
It has been known for quite some time that canines can sniff out stress in humans. However, a recent study by the University of Bristol discovered that sensing distress can also affect a pup. Researchers believe data from this study can enhance the lives of canines in kennels and working dogs, as they saw unfamiliar humans’ stress levels can also affect them.
Handlers have always stated that stress tends to travel down the leash. So, people must keep their mental state in check while training with dogs. This study further proves this belief, with senior lecturer at the University of Bristol’s veterinary school and lead author Dr. Nicola Rooney telling The Guardian, “…we’ve also shown it can also travel through the air.”
For the study, canines were introduced to two dog bowl locations, one with a treat and one without. Once they had caught on, pups approached the location with the treat faster. Their bowls were then placed in random locations between the two. A faster approach signaled optimism, and a slower one indicated pessimism.
Dogs exposed to the sweat and breath of stressed humans were slow to approach the bowls. They showed more doubts about whether the dog bowl would be empty than when exposed to the sweat and breath of relaxed individuals. Researchers pointed out that the canines tried to conserve energy and avoid disappointment when exposed to distressed people. This shows that being around humans in stress negatively impacted their optimism.
The research findings can be valuable for professionals who work with dogs. Trainers and handlers can use the data to understand canine companions and working dogs better. Moreover, shelter and rescue workers can also use the findings to enhance pups’ quality of life in kennels.
