Which of the following is a fear signal?

• A. A dog sprinting around play area.
• B. A dog huddled by the wall, door, or in a corner.
• C. A dog wagging tail and jumping.
• D. A dog rolling over for belly rubs.

Answer: (B)

Fear in dogs often shows as a desire to create distance and seek safety. A dog huddling by the wall, door, or in a corner is a classic signal of fear or stress—it's the body’s way of making itself small and avoiding direct interaction. The other behaviors are more about excitement or friendliness: sprinting around the play area usually means high energy or enthusiasm; wagging the tail with jumping can indicate excitement or anticipation; rolling over for a belly rub is typically an invitation for affection or submission. So the huddled posture best indicates a dog feeling afraid.
