Happy and angry human pictures differentially affect dogs’ postural stability

Key Points

• Dogs show different postural stability responses to happy and angry human emotions, indicating sensitivity to visual stimuli.
• The difference in postural stability was marked—happy images improved stability while angry images had the opposite effect.
• Observational analysis across various breeds examined canine responses to visual cues of human emotions.
• These findings highlight the importance of emotional cues in canine behavior, warranting further exploration of interspecies emotional communication.
