Need to speak “dog”? Here are a few tips to better understand your canine companion’s bark signals…..
Please remember that the meanings of any given bark can be modified by the nature of the sound dimensions expressed. For example, lower pitched barks should be interpreted as more dominant or threatening while higher pitched barks should be interpreted as meaning more insecurity or fear. Such emotional shading is added to each specific bark and can give you a clearer idea of what your dog is trying to say.
