What does frequent yawning in a non-tired dog often signal?

The story behind the answer

Frequent yawning in a non-tired dog is often a “calming signal” or displacement behavior—an attempt to self-soothe or de-escalate social tension. You’ll see it during mildly stressful moments: at the vet, when training gets too hard, during nail trims, or when approached too closely by people or other dogs. It’s the canine equivalent of saying, “I need a moment,” not a sign of sleepiness.

Trainers popularized the term “calming signals” (e.g., Turid Rugaas), which include yawning, lip licking, turning away, and sniffing the ground. Dogs also show contagious yawning, hinting at social attunement. Memory tip: If your awake dog yawns in tricky situations, think “yawn = chill request”—reduce pressure, give space, or make the interaction gentler.
