Quick answer
A quick lip lick is common and not automatically a problem. Repeated lip licking during handling, conflict, or a novel situation can be a sign that your dog is uncomfortable.

One signal has several causes
Moistening the lips is ordinary. The signal becomes more informative when it repeats or appears alongside other changes in posture and behavior.
During interaction, treat it as feedback
If lip licking appears during petting, hugging, grooming, or a close approach, pause. Giving space allows you to see whether the dog relaxes or chooses to re-engage.
Physical causes belong on the list
Nausea, mouth pain, dental problems, and other medical issues can also increase licking or swallowing. Behavioral context should not replace a health check when signs persist.
