A dog that is fearful and worried typically has which of the following signs?

A dog that is fearful and worried often displays specific behavioral signs that indicate its emotional state. The correct answer, indicating that a fearful dog may lick at the face of a dominant dog, highlights a submissive behavior. This action can be a sign of appeasement, showing the dog's attempt to communicate its non-threatening intentions and to avoid conflict. Licking is a way for the dog to demonstrate that it does not pose a threat, which is typical in dogs that are anxious or scared.

In contrast, other options suggest different emotional states. Ears pointing up usually indicate alertness or curiosity rather than fear. A mouth that is open in a relaxed manner typically suggests that a dog is comfortable and at ease, which does not align with the fearful state. Lastly, constricted pupils and an erect body posture may suggest aggression or heightened arousal, which again does not reflect a fearful demeanor, as a fearful dog tends to display more cowering or submissive body language.

Understanding these signs is crucial in assessing a dog's behavior and responding appropriately to their emotional needs during encounters.
