Bark Differences Between Distressed and Unsatisfied Dogs
Dr Karen Overall of the University of Pennsylvania and Dr Leslie Auguinick examined 30 dogs' barks to identify sonic differences between stressed dogs left home alone and unsatisfied dogs seeking to go out. They found distressed barks are high pitched and repetitive, while unsatisfied barks are more harmonic. The work, under review, explores how bark patterns reveal dogs’ requests for information about their environment and how vocalizations vary by breed and individual.
