How do scientists measure emotion recognition in dogs?

To measure emotion recognition in dogs, scientists primarily use behavioral observations like gaze direction, approach/avoidance, and tail wags in response to human or conspecific emotional cues. Physiological measures such as heart rate variability and cortisol levels provide insights into their internal emotional states. Most accurately, fMRI scans allow researchers to observe specific brain regions activating when dogs process different emotional expressions. These methods help determine how dogs interpret emotions, which, while not directly tied to astrology, influences their compatibility with owners.
