Understanding Lip Licking in Dogs
If your dog licks their lips often, they might be anxious, nauseous, or have allergies or dental pain. Sometimes, it’s as simple as dehydration or stress. I’ve seen this with my own dog, and it’s often a subtle sign that something’s wrong. Watch for other symptoms like drooling or a change in appetite. If it happens often, don’t ignore it—check with your vet to keep your pup healthy and happy.
What Does It Mean When My Dog Licks His Lips?
If your dog keeps licking his lips, it could mean he’s feeling nervous, unsure, or even trying to calm himself down. Dogs use body language like this to communicate since they can’t tell us how they feel. My own dog often licks his lips when I raise my voice—it’s his way of saying, “I’m not a threat.”
This behavior can also happen when they’re nauseous, in pain, or dealing with allergies. Pay close attention to when and how often it happens. If it happens a lot and you can’t link it to food or training, check for other signs. Look for drooling or if your pet avoids meals. When in doubt, a quick call to your vet can help put your mind at ease.
Why Is My Dog Licking His Lips So Much?
If your dog has been licking his lips a lot lately, you’re not alone. This common behavior can mean different things. Sometimes it’s harmless, like waiting for food or having a dry mouth. But it can also mean stress, nausea, allergies, or dental issues. As a pet owner, I found that my dog licked his lips when he felt anxious during thunderstorms.
Vets often stress the need to look for other signs, such as drooling, shaking, or changes in appetite. These can help identify the root cause. When in doubt, a quick vet visit can give you peace of mind and help your pup feel better fast.
Physical Health Causes
Dehydration
Wondering why your dog’s licking his lips a lot? As a pet parent, I’ve been there, and it can worry you! Dehydration is one cause, making their mouth dry, so they lick to moisten it. It can happen from not drinking enough, especially in the heat or after play. But stress, nausea, or health issues might also be reasons.
Here’s how to tackle dehydration-related lip licking.
- Spot dehydration: Look for dry gums, sunken eyes, or tiredness. Pinch their skin—if it stays up, they may be dehydrated.
- Provide water: Keep fresh, cool water out. I add a bit of chicken broth if my dog’s fussy.
- Track drinking: Dogs need ~1 oz of water per pound daily. A pet fountain can encourage sipping.
- Mind the heat: Limit hot-weather play and carry water on walks.
- See a vet: If lip licking won’t stop, a vet can check for other issues. My dog’s licking was once from nausea, not dehydration!
- Reduce stress: Anxiety can cause licking, so keep their space calm with a comfy bed.
Keep your pup hydrated, but if lip licking persists, a vet visit ensures they’re okay. Your dog deserves to feel great!
Dental Disease
If your dog keeps licking his lips, it could be more than a habit—dental disease might be the reason. I’ve seen this with my own dog, Max, who started licking constantly due to inflamed gums from tartar. Dental problems such as plaque, gingivitis, or sore teeth can cause dogs to lick, drool, or paw at their mouths. Left untreated, these problems can lead to serious health issues.
What to do:
- Check for signs: Bad breath, red gums, tartar, or trouble eating.
- See the vet: A checkup can catch infections or tooth decay early.
- Brush their teeth: Use dog-safe toothpaste a few times a week.
- Try dental chews: They help control plaque between brushings.
- Check for objects: Sticks or bones stuck in the mouth can cause discomfort.
- Act early: Dental problems get worse fast—early care saves pain and money.
To help your dog stay pain-free, watch for small signs, like lip-licking. When in doubt, your vet can guide you.
Nausea
If your dog is licking his lips a lot, nausea might be the reason. I’ve seen it with my own pup—after sneaking some table scraps, he started licking like crazy. When dogs feel nauseous, they drool more and lick their lips to manage the saliva.
- Why it happens: Nausea causes excess drool, and lip licking helps them cope.
- Signs to look for: Vomiting, not eating, or eating grass.
- Common causes: Spoiled food, car rides, stress, or tummy bugs.
- What to do: Offer water, skip a meal, and keep them calm. If it doesn’t improve, call the vet.
- Serious signs: Lethargy, diarrhea, or repeated vomiting—see a vet fast.
- Prevention: Stick to a stable diet, no table scraps, and secure your trash.
If something feels off, trust your gut—a quick vet visit can make all the difference.
Allergies
If your dog keeps licking their lips, allergies could be the reason. Dogs can react to food, pollen, dust, or even mold. These allergies can make the face itchy and irritated. As a result, they often lick their lips for relief. I’ve seen it firsthand—it’s tough watching your dog feel uncomfortable. Thankfully, there are ways to manage it once you know what’s triggering the allergy.
Signs your dog may have allergies:
- Itchy, red skin (especially on face, paws, or ears)
- Constant scratching or rubbing
- Watery eyes or sneezing
- Recurring ear infections
- Licking or chewing paws
- Upset stomach or vomiting (food allergies)
- Worse symptoms in spring or fall
If you spot these symptoms, talk to your vet. They might suggest allergy testing, special diets, or medications. With the right care, your pup can feel better fast.
Your Dog Feels Sick
If your dog keeps licking his lips, it might be a sign he’s feeling sick. This behaviour often connects to nausea, stomach upset, or even serious issues like liver problems. I once noticed my dog doing this before he threw up—turns out he had eaten something bad. If lip licking comes with drooling, low energy, or no appetite, it’s time to call the vet. Trust your instincts—your dog’s trying to tell you something.
Bloat
If your dog licks their lips and appears restless, it might signal bloat. This condition is serious and can be life-threatening. Bloat occurs when a dog’s stomach fills with gas, food, or liquid. This causes the stomach to expand and may twist, blocking blood flow.
I’ve seen it firsthand with my Labrador, and it moves fast. If your dog is showing odd signs, don’t wait—call your vet immediately.
Signs of Bloat in Dogs:
- Constant lip licking and anxiety
- Pacing, panting, or restlessness
- Dry heaving with no vomit
- Swollen belly
- Weakness or collapse
- Fast heartbeat or breathing trouble
Big dogs like Great Danes and German Shepherds are more at risk. If you suspect bloat, act fast—it could save your dog’s life.
Seizures
If your dog licks his lips often, it might be more than a habit. It could signal a mild seizure, especially focal or partial ones. These types don’t always look dramatic. Instead, they show up in subtle ways, and many dog owners miss the signs.
Possible Seizure Signs in Dogs
- Lip licking without reason
- Staring or zoning out
- Twitching in the face or jaw
- Confused or dazed behavior
- Drooling or foaming
- Restless pacing before/after
If you notice these signs, call your vet. Seizures can have several causes, and a proper check-up can help determine what’s really going on.
Vomiting
If your dog keeps licking his lips and throwing up, it’s usually a sign of nausea or tummy trouble. I’ve seen this with my dog—it’s often how they show discomfort. While it might be something minor, like eating too fast, it can also be a sign of something more serious.
Common reasons your dog may lick its lips and vomit:
- Nausea – Often a warning sign right before vomiting.
- Food allergies – New foods or treats can upset their stomach.
- Gastritis – Eating spoiled food, grass, or trash causes stomach irritation.
- Parasites/infections – Worms or bacteria can trigger vomiting.
- Motion sickness – Common during or after car rides.
- Toxins – Dogs sometimes eat harmful things.
- Dental issues – Mouth pain or something stuck can cause lip licking.
If your dog keeps vomiting, seems weak, or won’t eat, it’s smart to call your vet. Catching issues early keeps your furry friend safe and healthy.
Eating Grass
Have you noticed your dog licking his lips and then eating grass? It might seem odd, but many dog owners in the U.S. see this too. I’ve seen it with my own pups, and it’s often a sign that something’s not right with their stomach. Dogs lick their lips when they feel queasy, and eating grass may help them throw up and feel better.
Here are some quick reasons your dog may be doing this:
- Mild nausea: Grass helps them vomit to ease the discomfort.
- Diet issues: They might need more fiber or nutrients.
- Indigestion or acid reflux: Grass can help calm the tummy.
- Anxiety or stress: Dogs lick or eat grass to soothe themselves.
- Parasites: Worms or gut issues could be the cause.
- Boredom or curiosity: Especially common in puppies.
If it happens once in a while, it’s usually no big deal. But if your dog keeps doing it or shows signs like vomiting or tiredness, it’s best to check with your vet.
Dog Licking Lips and Not Eating
If your dog keeps licking his lips and throwing up, it’s usually a sign of nausea or tummy trouble. I’ve seen this with my own dog—it’s often how they show discomfort. While it might be something minor, like eating too fast, it can also be a sign of something more serious.
Common reasons your dog may lick its lips and vomit:
- Nausea – Often a warning sign right before vomiting.
- Food allergies – New foods or treats can upset their stomach.
- Gastritis – Eating spoiled food, grass, or trash causes stomach irritation.
- Parasites/infections – Worms or bacteria can trigger vomiting.

If your dog keeps vomiting, seems weak, or won’t eat, it’s smart to call your vet. Catching issues early keeps your furry friend safe and healthy.
Sneezing
If your dog licks his lips and sneezes a lot, it might mean he’s uncomfortable. This could be just a small irritation or something more serious. As a dog owner, it’s important to recognize the signs early.
Here are common causes:
- Allergies – Pollen, dust, or certain foods can irritate your dog, leading to sneezing and lip licking.
- Foreign object in nose/mouth – Grass, dirt, or seeds can get stuck. This may cause sneezing and lip licking as your dog tries to get rid of them.
- Nausea – Dogs often lick their lips when they feel nauseous, especially if sneezing accompanies it.
- Dental issues – A sore tooth or gum problem can lead to this behaviour. Sneezing may also signal pain that affects the nasal area.
- Upper respiratory infection – Colds or mild infections can cause sneezing, lip licking, and watery eyes.
If the behavior persists or worsens, contact your vet for a checkup. They’ll help identify the cause and get your dog feeling better quickly.
Due to Sleep reason
If you’ve noticed your dog licking their lips while snoozing, you’re probably wondering what’s going on. As a dog owner myself, I’ve seen my pup do this and felt that mix of curiosity and concern. Lip-licking in sleep can be normal sometimes. But it may also indicate issues like discomfort, stress, or health problems.
After digging into this with help from vets and my own experience, I’ve put together the most common reasons why dogs lick their lips while sleeping. Let’s break it down so you can figure out what’s happening with your furry friend and how to help them.
After Drinking Water
Ever catch your dog licking their lips right after a big gulp of water? It’s pretty common. When my dog drinks, she sometimes licks her lips even in her sleep, almost like she’s savoring the last drops.
This can happen because:
- Residual moisture: Water may stay near their mouth, causing them to instinctively lick it away, even in light sleep.
- Reflex action: Drinking stimulates their tongue and mouth, and that motion can carry over into sleep as a muscle memory thing.
- Hydration habits: If your dog drinks a lot before bed, their body might still be processing that, leading to lip-licking.
If this only happens after drinking and there are no other symptoms, it’s usually harmless. Just make sure their water bowl is clean to avoid any irritation from bacteria.
Drooling
Drooling and lip-licking often happen together. This is common in breeds with loose jowls, like Mastiffs and Bulldogs. I remember my old Lab would drool in his sleep, and the lip-licking seemed to be his way of managing it. Here’s why drooling might cause lip-licking:
Saliva buildup: Excess saliva can pool in the mouth during sleep, triggering a need to lick to clear it.
- Dental issues: Things like gum disease or tooth pain can increase drooling, which might make your dog lick more. Check for bad breath or red gums.
- Relaxation: Deep sleep can relax their jaw, letting saliva slip out, which they instinctively lick away.
If drooling is excessive or new, a vet visit is a good idea to rule out dental problems or neurological issues. Keeping their sleeping area clean can also help them stay comfortable.
Swallowing
Swallowing and lip-licking during sleep can look similar, and it’s something I’ve noticed with my dog when she’s dreaming. It’s like she’s processing something in her sleep!
This might happen because:
- Dreaming: Dogs dream just like us, and lip-licking or swallowing could be part of a dream about eating or drinking.
- Dry mouth: If their mouth feels dry (maybe from panting earlier), they might lick or swallow to moisten it.
- Digestive reflexes: Their stomach might be handling dinner, causing tiny throat or mouth movements like licking.
If your dog seems peaceful and this is occasional, it’s likely just a quirk. But if they’re swallowing a lot or seem restless, it could point to nausea or acid reflux, so check with a vet.
Foaming
Foaming at the mouth while licking lips is a red flag and something that always makes me worry. I’ve never seen this with my dogs, but I’ve heard from friends who’ve dealt with it.
It’s not common and could mean:
- Seizures: If your dog foams at the mouth or licks its lips while sleeping, it might be having a seizure. This is more likely if your dog seems stiff or unresponsive. Call a vet immediately if you suspect this.
- Toxins: Ingesting something toxic, like household cleaners or certain plants, can cause foaming. Check your home for anything they might’ve gotten into.
- Oral irritation: A foreign object, like a stick or bone fragment, stuck in their mouth could cause foaming and licking.
- If you see foaming, don’t wait—contact a vet right away. Take note of any other symptoms, like shaking or vomiting, to help the vet figure out what’s wrong.
Most of the time, lip-licking while sleeping is not a big deal. However, it’s important to watch for patterns and other symptoms. If your dog seems uncomfortable, licks a lot, or has symptoms like foaming or drooling, a vet can help find the cause. For now, give your pup some extra love and maybe a cozy blanket to snooze on—they’ll appreciate it!
Pain
Dogs can’t say they’re in pain, but their body language speaks volumes, like lip licking. If your pup keeps licking his lips without food around, it could signal discomfort. Pain in joints, muscles, or hidden areas like the belly or mouth can trigger this behavior. Dogs with arthritis or unseen injuries may lick their lips as a way to cope. Watch for other signs like limping, hiding, or being less active. If something feels off, a vet visit is the best step to keep your dog safe and comfy.
Mouth Pain
If your dog keeps licking their lips, it might be a sign of mouth pain—and as a dog owner, I’ve been there. My pup started doing this, and I brushed it off at first. But soon, I saw he was struggling to eat and didn’t want to chew his toys. A vet visit revealed a sore tooth causing real discomfort.
Dogs can’t talk, so they show pain in small ways, like lip licking. Mouth pain may come from gum disease, broken teeth, or even something stuck in the mouth. Signs like bad breath, drooling, or face pawing mean it’s time to see the vet. Catching it early can ease their pain and prevent bigger problems.
Conclusion
If you’re wondering, “Why does my dog keep licking his lips?” it could be due to stress, nausea, allergies, dental pain, or even dehydration. Watching for signs like drooling, vomiting, or not eating can help you figure out what’s wrong. As a dog owner, I know it’s worrying, but a quick vet visit can keep your pup healthy and happy. Trust your instincts and act fast if something feels off. Your furry friend deserves to feel their best!
