Which sign indicates stress requiring session adjustments in a dog during exposure?

• A. Yawning
• B. Lip licking
• C. Pupil dilation
• D. Panting

Answer: (D)

Noticing when a dog’s arousal level shifts during exposure and adjusting the session accordingly is essential for keeping learning in a safe zone. Panting is a clear, outward sign that the dog is becoming stressed or overwhelmed with the current exposure—enough to warrant a pause or a reduction in difficulty. When you see panting, consider shortening the exposure, lowering intensity, or switching to a calmer task to prevent escalation into fear or avoidance. It’s also wise to check for overheating and ensure fresh air and water are available. Yawning, lip licking, and pupil dilation can also occur with stress or cognitive processing, but they’re less reliable indicators for deciding to adjust a session. Yawning and lip licking can be part of normal processing or mild tension, and pupil dilation varies with different contexts and levels of arousal, making them less actionable on their own. Panting provides a more direct cue that the current challenge may be over the dog’s comfort threshold.
