What does a dog yawning during a stressful event typically signify?

• A. A calming signal indicating stress or discomfort; not necessarily sleepiness.
• B. It indicates sleepiness and should be ignored.
• C. It means the dog is happy.
• D. It signifies readiness to attack.

Answer: (A)

Yawning in a dog during a stressful event is a calming signal. It isn’t about sleepiness; rather, it’s a way for the dog to reduce arousal and communicate discomfort to others. When things feel tense, a yawn can help the dog diffuse the situation and invite a de-escalation from a human or another dog. So, in this moment, yawning signals stress or unease, not happiness or aggression, and not tiredness. Observing it alongside other body cues—such as a soft, avoiding gaze, a tucked tail, or a lowered, relaxed posture—helps confirm that the dog is trying to calm things down rather than provoke a reaction.
