Fear-based aggression
Fear-based aggression is defensive aggression shown by an animal that perceives a threat and cannot escape it. It is the most common form of aggression in dogs and is often directed at unfamiliar people or animals. The behaviour is reinforced when the threat retreats, making it self-perpetuating.
