Short answer: Yes – dogs make a relaxed open-mouth ‘smile’ that researchers call a ‘play face’ or ‘submissive grin.’ It’s a social signal communicating relaxed, non-threatening intent, usually paired with soft eyes and loose body. A tight, lip-pulled-back grimace is the opposite – that’s a warning.
What you should actually do
- Play face: open mouth, relaxed lips, soft eyes, tongue lolling – ‘I’m having fun.’
- Submissive grin: lips pulled back over teeth in some friendly dogs (often huskies, retrievers) – looks like a snarl to humans, is actually appeasement.
- Warning snarl: lifted lip, exposed canine, hard stare, stiff body, growl – leave the dog alone.
- Dog smiles are visibly different to other dogs – they don’t read it as a threat the way they’d read a true bared-teeth display.
- Smiling is reinforced by humans laughing/petting – dogs learn it gets attention.
The submissive grin is one of the most misinterpreted canine behaviors. Some dogs (notoriously Huskies and Labs) flash all their teeth in a wrinkly-nose grin during enthusiastic greeting – looks aggressive, is the opposite. The whole-body picture (wiggling hind end, raised paw) confirms it’s friendly.
Watch for true warning signs: stiff body, hard direct stare, lifted lip with weight shifted forward, low growl. Those are precursors to a bite and the dog needs space, not interaction.
