Dogs are widely accepted as “man’s best friend,” and they seem to have a knack for understanding human intentions and emotions. Recent research has shown that dogs have the ability to recognize emotions in human voices, facial expressions, and body postures. In a study published in the journal Animal Cognition, researchers examined the effects of training on dogs’ ability to recognize emotions in human voices. The results showed that dogs were able to accurately identify different human emotions, including anger, happiness, and sadness, regardless of tone of voice or context. These findings suggest that dogs may play an important role in human social interaction and well-being.
