By Dr. Duncan Houston BVSc
Lip licking in dogs is common—but constant licking isn’t just cute, it may signal a need. Here’s a vet-approved breakdown of normal vs concerning lip-licking and what you can do.🩺
✅ Normal Reasons for Lip Licking
- 🍽️ Hunger or food smells: Anticipating meals or treats leads to lip-licks.
- 😋 Post-eating clean-up: After mealtime, dogs lick lips to tidy up food residue.
- 🤩 Excitement or anticipation: Happy or eager pups may lick in eager anticipation.
⚠️ Common Warning Signs Behind Lip Licking
Look for these signs alongside licking—frequent lip-licking with other symptoms may point to a deeper issue.
- 😰 Stress or anxiety: A calming or appeasement signal when dogs are uncomfortable, confused, or nervous.
- 🦷 Dental pain or foreign object: Dental disease, abscesses, broken teeth, or stuck debris can prompt lip-licking.
- 🤢 Nausea or GI upset: Nauseated dogs often lick lips, drool, vomit, or eat grass.
- 🚰 Dehydration: Dry mouth or thirst may cause lip-smacking.
- 🤧 Allergies or itchiness: Lip-licking can accompany itchy lips or allergic reactions.
- 🔄 Compulsive licking: OCD-like behaviors cause repetitive lip-licks or licking at night.
🧪 Check for Other Signs
- Pawing at the mouth, head shaking, reluctance to eat
- Vomiting, diarrhea, loss of appetite
- Excessive drooling or bad breath
- Pacing, whining, yawning, or lip licking during petting or training
🩺 Vet‑Approved Action Plan
