Most dog owners can sense the difference between Fido’s yip of joy and howl of discontent. Now, scientists find people use the same general rules to recognize doggy emotions as they do for fellow humans.

According to the study, People linked positive or negative emotions with the length of a vocalization, and the emotional intensity with a sound’s pitch.

Emotions reflect a person’s mental state, and the evolutionary roots of emotions go way back. Emotional vocalizations are quite similar across different species, and may carry the same information about an animal’s inner state as about a human’s.
