How Dogs Can Smell When You're Stressed

The video discusses a study published in PLOS ONE about dogs' ability to detect human stress through smell. The experiment involved dogs identifying stressed individuals based on sweat and saliva samples, showing a 94% success rate. This research could enhance training for service dogs aiding anxiety and PTSD. Additionally, the video explores a study on personality changes during the COVID-19 pandemic, revealing shifts in traits like neuroticism and agreeableness, especially among younger adults.
