Which of the following is NOT a distance increasing signal?

• A. Wagging tail
• B. Lip licking
• C. Air snapping
• D. Flagging tail

Answer: (A)

Distance-increasing signals are cues that prompt others to back away or create space. The wagging tail is typically a friendly, inviting sign that accompanies social contact or play, so it does not serve to push others away. In contrast, air snapping is a clear threat display meant to warn and cause distance to be created. A tail held high and flagged can signal arousal or a challenge, prompting retreat or avoidance. Lip licking is a calming, appeasement gesture used to diffuse tension and encourage space between individuals. Among these, the wagging tail stands out as not increasing distance.
