What does a fearful and aggressive dog typically exhibit?

A fearful and aggressive dog often exhibits specific body language that signals its emotional state. One of the most telling signs is raised hackles along the back, which indicates arousal and can be a response to fear or aggression. Additionally, a tucked tail suggests submission or anxiety, reinforcing the idea that the dog feels threatened or insecure. Both of these behaviors combined reflect a defensive posture, commonly associated with fear and aggression in canines.

This behavior is in sharp contrast to other options provided. Ears perked forward often indicate curiosity or alertness, which is not typical for a dog that is fearful or aggressive. Relaxed eyes would signify a calm demeanor, whereas focused eyes could mean the dog is fixating on a potential threat in a more neutral way rather than displaying genuine fear or aggression. Moreover, a mouth open with a relaxed stance implies comfort and relaxation, which is contrary to the behaviors exhibited by a fearful and aggressive dog. Understanding these signs can significantly aid in assessing a dog's emotional state and determining the appropriate response in a given situation.
