A dominant aggressive dog shows which of the following characteristics?

The characteristic of a dominant aggressive dog is best represented by a nose that is wrinkled, lips curled, and teeth visible. This physical display is typically a sign of aggression and an assertion of dominance. The wrinkled nose and curled lips can indicate that the dog is preparing to growl, snarl, or show its teeth in a threatening manner. This posture is often meant to warn others of its readiness to defend its territory or assert itself over other animals or people.

The other descriptions, while they may suggest different emotional states in dogs, do not align with the typical signs of a dominant aggressive dog. For instance, pupils that are dilated and a body that is lowered usually indicate fear or submission rather than dominance. Similarly, a tail that is down and relaxed is often associated with a non-threatening or submissive state rather than one of aggression. Lastly, a smooth forehead and ears positioned back may signify stress or submission, which contrasts with the confident and assertive stance of a dominant aggressive dog. Understanding these distinctions helps reinforce the correct identification of a dog’s emotional state during encounters.
