Why Do Dogs Yawn?

Do dogs yawn because they're tired?

Sometimes, yes. Just like humans, dogs yawn when they're winding down for sleep or first waking up. If your dog stretches and yawns after a nap or at bedtime, that's the straightforward version; they're just tired. No mystery there.

Why does my dog yawn so much when they're not sleepy?

This is the one most people miss. In dog body language, yawning is what Norwegian dog trainer and researcher Turid Rugaas classified as a "calming signal" in her influential work on canine body language. Dogs use it to self-soothe when they're feeling stressed, anxious, or uncomfortable. You might notice your dog yawning during a vet visit, when being hugged by a stranger, during training sessions, or in tense social situations with other dogs. It's not a sign of boredom; it's a sign of mild stress. Think of it as your dog taking a deep breath to settle their nerves.

Can dog yawns be contagious?

Actually, yes. Research from the University of Tokyo has shown that dogs can "catch" yawns from humans, and some studies suggest that dogs are more likely to yawn in response to their owner yawning than a stranger yawning. This is thought to be connected to empathy and social bonding. Dogs that are more emotionally attuned to their owners tend to be more susceptible to contagious yawning. So if your dog yawns every time you do, it might actually be a sign of how connected they feel to you.

Should I be concerned about excessive yawning?

If your dog is yawning a lot in situations that are clearly stressful for them, the yawning itself isn't the problem, but it's a useful signal that your dog is uncomfortable and might need a break or some reassurance. Pay attention to the context. If they're yawning during a new experience or around unfamiliar people, they might just need some space. If excessive yawning is paired with other signs like drooling, pacing, or loss of appetite, it's worth mentioning to your vet in case something physical is going on.
