Fear aggression in dogs can be displayed through various signs, including growling, barking, baring teeth, lunging, or even biting when they feel threatened or scared. Other signs may include cowering, trembling, ears pinned back, tail tucked, and avoiding eye contact. It's important to understand that fear aggression is a defensive response and not a sign of dominance. Dogs may exhibit fear aggression in situations that trigger their anxiety or discomfort, such as meeting new people or encountering unfamiliar environments. It's crucial to address fear aggression through positive training methods, desensitization, counterconditioning, and seeking professional help if needed.
