Subtle signs a dog is stressed include lip licking, yawning outside of sleep, showing the whites of their eyes ('whale eye'), turning their head away, stiffening their body, excessive panting, and slow tail wags. These 'calming signals' are low-level communication attempts to diffuse discomfort before a dog feels forced to growl or bite.

The Ladder of Canine Aggression
Dogs rarely bite ‘out of nowhere.’ Dogs communicate stress through a
predictable hierarchy of body language. When subtle calming signals are
ignored by owners (e.g., hugging a dog while they yawn and look away),
the dog learns that low-level communication fails, forcing them to jump
straight to growling or snapping.
