Noises off: What vocalizations can and can't tell us about animal welfare

Caroline J. Hewson

The method was more advantageous over less specific indices due to its multidimensional nature and its specific role in communication. Other such research included the effect on dogs in shelters of the noise from barking and stereotyped vocalization as a sign of extreme frustration.
