Bark (sound)

A bark is a sound most often produced by dogs. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals, frogs and owls. Bark is also a verb that describes the sound of many canids.

There is no precise, consistent, and functional acoustic definition for barking, but researchers classify barks according to several criteria. Researchers at the University of Massachusetts Amherst and Hampshire College have defined a bark as a short, abrupt vocalization that is relatively loud and high-pitched, changes in frequency, and often repeats rapidly in succession.
