Why does my dog constantly lick her lips, even without dental issues?

Updated On September 23rd, 2025

Okay. I know people say it's insecurity, but my dog is always slurping her lips 24/7 non stop. No dental issues what's so ever. I don't understand why she doesn't get tired of doing it. And it's as loud as she can be! It gets to the point of having to put her out of the same room as you. Why do dogs do this? (She's very happy and alert, and always prideful when walking)

Lip licking can sometimes indicate nausea in dogs, so if that hasn't been ruled out its a possibility. Behaviorally, it can sometimes indicate your dog is feeling a little unsure of the situation. Even if she is standing tall with tail raised or ears forward, she may not still be as confident as you think she is. If she's doing the behavior just sitting at home, it may be more of a learned boredom behavior, and trying to stop it by distracting her with puzzle toys or a good bone may help.
