Detailed explanation-1: -Aggression is defined as threats or harmful actions directed toward another individual and can include threat displays, lunging, growling, snarling, snapping, and biting. “In animals, aggressive behaviors are a means of communication."

Detailed explanation-2: -"Fear or anxiety related aggression is perhaps the most common form of aggression in dogs.” Early manifestations of fear related aggression are typically defensive, displayed to increase the distance between the perceived threat, or communicate ‘stay away’, yet aggression may become more offensive through learning.

Detailed explanation-3: -As a general rule, a dog’s level of attention can be determined by watching their ears: Erect ears facing forward indicate that they’re engaged, and slightly pulled-back ears signal that they’re feeling friendly; but dog ears laid tightly back against the head suggest a fearful or timid reaction.
