"The good thing about studying dogs' body language is that you become aware of the meaning of every slight change in their behavior. Most people think that the only indication that a dog will bite is if it barks or growls. This is a huge misconception. There are, in fact, other predictive gestures that may occur prior to a bite and they always go unnoticed by an untrained eye. This is the main problem in human-dog relationships --- the language barrier. Before dog owners can hope for obedience, they should understand first what is going through the mind of the dog."
