Emphasizing our strong bonds that we have with our dogs, a new study reveals dogs can smell the stress odors humans produce.
Your dog doesn’t just use its nose to find leftovers on the counter or that aging piece of garbage on your walks. It actually uses its nose to discover critical information, like recognizing family members, identifying predators and, of course, locating food.published infound that dogs can detect when humans are stressed based on the odor profiles we produce.
“This study demonstrates that dogs can discriminate between the breath and sweat taken from humans before and after a stress-inducing task. This finding tells us that an acute, negative, psychological stress response alters the odor profile of our breath/sweat and that dogs are able to detect this change in odor,” conclude the authorsBroadly speaking, stress is a physiological and psychological response triggered during a challenging situation you don’t believe you can overcome.
For humans, stress alters our odor profiles for breath and sweat, which are typically used for communication among our own species, according to the study. But because of the close domestication we’ve developed with dogs throughout history, it’s possible that dogs can sense this form of communication, too.
