New Study Reveals Dogs Can Detect Stress in Humans

A landmark study published in the journal PLOS ONE has confirmed that dogs can detect stress through changes in human breath and sweat, with an accuracy rate of 93.75%.

Researchers collected breath and sweat samples from participants before and after a stressful math task. Trained dogs were then asked to identify which samples came from stressed individuals.

This finding has significant implications for the training of therapy and service dogs, particularly those working with PTSD patients and anxiety disorders.

If you've ever noticed your dog being extra attentive when you're having a bad day, it's not coincidence. They're responding to chemical changes in your body that signal distress.
