Frequent Does stress make dogs smell? Get Your Pet Thinking

“Our bodies’ psychological stress response changes the smell of our breath and sweat,” says Clara Wilson, a psychologist at Queen’s University Belfast in Northern Ireland and one of the study’s authors, to Gizmodo’s Ed Cara. “Dogs can detect this change.”

Previous research suggests that dogs might be able to smell when humans are happy or fearful. But the researchers behind this latest study were curious about stress, an all-too-common reaction to the hassles of everyday life, especially amid the COVID-19 pandemic.

Though dogs may be able to tell when a human smells stressed, it’s unclear whether they feel or behave any differently because of the odor—the study didn’t attempt to answer that sort of question. But, as Katherine Houpt, a veterinarian and animal behaviorist at Cornell who was not involved in the study, tells NBC News, dogs do seem to care when something is wrong with their humans, and “that’s why they make good emotional therapy animals.” Recommended Videos Most Popular

“This study provides further evidence of the extraordinary capabilities of ‘man’s best friend,’” says Wilson to NBC News’ Linda Carroll.

The researchers then exposed these dogs to three different scents: a standard piece of gauze, a sample from an unstressed human and a stressed odor sample. The four dogs were incredibly adept at sniffing out the stressed sample, achieving a combined 93.8 percent accuracy rate. Though the study was small, the findings suggest that humans who are stressed out may emit odors that differ from their normal smell—different enough, at least, that dogs’ highly sensitive noses can tell something’s up.
