Dogs Can Detect Human Emotions Through Scent and Body Language

Dogs have an extraordinary ability to read human emotions, and science is beginning to understand just how sophisticated this skill is. Studies have shown that dogs can detect changes in human emotional states through chemical cues present in sweat and breath. When humans experience different emotions, our bodies release different chemical compounds that dogs can detect with their incredibly sensitive noses. Dogs can distinguish between the scent of a fearful person and a calm person, and they adjust their behavior accordingly. This ability likely developed through thousands of years of domestication and close cohabitation with humans. It explains why dogs often seem to know when we are sad, anxious, or happy before we have even consciously processed those emotions ourselves. This emotional intelligence is one of the many reasons dogs make such exceptional companions.
