Dogs React to Human Stress and Moods: New Study Reveals Surprising Insights A groundbreaking study conducted by researchers at the University of Bristol has revealed that dogs can detect human stress through smell, which significantly affects their behavior and emotional state. The study, published in Scientific Reports, is the first to explore how human stress odors impact dogs' learning and emotional responses1. The research involved 18 dog-owner pairs who participated in a series of trials where dogs were exposed to sweat and breath samples from humans in either a stressed or relaxed state. The findings showed that dogs exposed to human stress odors made slower, more "pessimistic" choices, indicating a negative emotional state1. This emotional contagion suggests that dogs can sense their owners' stress and respond accordingly. The study highlights the deep connection between human emotions and canine responses, emphasizing the importance of managing our stress levels for the well-being of our furry companions. The researchers believe that understanding this connection can improve the training and care of companion and working dogs1. This research adds to the growing body of evidence that dogs are not just pets but sensitive and empathetic beings who can mirror our emotions. So, the next time you're feeling stressed, remember that your dog might be feeling it too!
