Definition of aggression
Aggression can be defined as a set of behaviors that the subject uses to intimidate or damage another subject in various situations and it’s regulated by both genetics and adaptation to the environment.
Aggression shouldn’t be confused with a lack of sweetness.
Sweetness is a characteristic that makes the dog act in obedience. If the subject lacks this characteristic, it will tend to show dominance even if it’s not necessarily aggressive.
Aggression is instead, intimately related to specific hormonal mechanisms that influence the metabolism.
