Dog Constantly Lick His Lips

Why Does My Dog Constantly Lick His Lips?

Why Does My Dog Constantly Lick His Lips? If you’ve ever noticed your dog licking his lips frequently, you’re probably wondering why. There are a few possible explanations for this behavior, and it’s important to be aware of them to determine if it’s a cause for concern. 

In this blog post, we’ll explore some common reasons why your dog may be licking his lips and provide advice on what to do if the behavior becomes excessive.


Your dog may be constantly licking his lips due to allergies. Allergens in the environment, such as pollen, dust, mold, or grass, can cause your pup to lick his lips excessively. 

Allergens can also cause a dog’s mouth to become dry and irritated, which leads to increased licking. If you think your pup may have an allergy, talk to your vet about medications that can help alleviate the symptoms.


If your dog is licking his lips more than normal, it could be due to anxiety or stress. Dogs often lick their lips as a sign of insecurity, fear, or nervousness. If you think your dog may be stressed or anxious, look for other signs such as panting, shaking, and cowering. 

You should try to identify what might be causing your dog’s anxiety so that you can take steps to help them relax. Common causes of anxiety in dogs include unfamiliar people, loud noises, changes in the home environment, separation anxiety, and anything else that might make them feel unsafe or uneasy. 

If your dog’s lip-licking behavior is due to anxiety, the best way to help them is to create a calm and safe environment for them. Providing them with plenty of exercises and mental stimulation can also help reduce their stress levels. If your dog’s anxiety is persistent and hard to manage, you should consult with a vet or animal behaviorist.

Dry Mouth Or Dehydration

A dry mouth or dehydration can be a common cause for dogs to lick their lips excessively. Dehydration is caused when your dog does not consume enough water and their mouth becomes dry and uncomfortable. 

Dogs with underlying health conditions may be more prone to dehydration due to an inability to consume enough fluids. 

Signs of dehydration can include excessive panting, sunken eyes, dry gums, a decrease in skin elasticity, lack of energy, and an increase in thirst. If your dog is licking his lips more than usual, it may be time to take them to the vet to check if they are dehydrated.

If you think that your dog is dehydrated, it’s important to act fast. Make sure your pup has easy access to fresh, clean water, and provide food that is high in water content like fruits and vegetables. Additionally, consider adding electrolyte powders or pet-friendly hydration supplements to your dog’s water bowl to help ensure they stay hydrated.

Excess Drool

Dogs can sometimes produce an excessive amount of drool, usually caused by some kind of stressor or excitement. It could be due to something as simple as being excited to see you or smelling food in the kitchen. 

In these cases, the drooling is usually not a cause for concern and will stop once the excitement wears off. However, if your dog is drooling more than usual and it’s not due to any kind of excitement, it could be a sign of a medical condition that needs attention.

A few medical conditions can cause your dog to drool excessively. One of these is gastroesophageal reflux disease (GERD), which is an inflammation of the esophagus that causes acid to flow back up into the mouth. 

This can result in increased saliva production, which can lead to excess drooling. Other medical conditions that can cause excessive drooling include gastric dilatation volvulus (bloat) and liver disease. If your dog is exhibiting any other symptoms along with droolings, such as vomiting, diarrhea, or loss of appetite, then it’s best to take him to the vet right away.

Excessive drooling can also be caused by allergies, pain, or even anxiety. For example, if your dog has an allergic reaction to something he ate or was exposed to, it could trigger an overproduction of saliva. 

The same can happen when a dog is in pain; his body produces extra saliva to protect the mouth from potential damage. Finally, if your dog is anxious or stressed out, he might start drooling as a result.

If your dog is drooling excessively and you’re unsure of the cause, it’s important to take him to the vet as soon as possible. Only a professional can determine the exact cause of your dog’s excessive drooling and provide the necessary treatment.


If your dog is running a fever, it may be licking its lips more than usual. When the body temperature rises, it can cause dogs to become excessively thirsty and seek out water or something else to help cool down. 

If your dog has been running a fever, you may also observe them panting heavily and seeking out colder surfaces such as the floor to help cool off. If you suspect your dog has a fever, consult with your veterinarian for advice and treatment.


Is your dog constantly licking his lips because he is hungry? It’s possible, especially if you have a dog that loves to eat. Dogs will often lick their lips when they are anticipating food, which can become a habit over time. 

If your pup is always licking his lips and it seems to coincide with meal times, it might be due to hunger. To test if this is the case, try not feeding your dog for a few hours and see if the lip licking persists. If it does, then chances are hunger is not the cause of your pup’s lip licking.


It’s always important to pay attention to your dog’s behavior and take note of any unusual licking or lip-licking activities. If the behavior persists, it is best to seek the help of a veterinarian who can provide a diagnosis and advice on how to proceed with treatment. 

While many of the causes of lip-licking are harmless, some conditions require veterinary care. Regardless of the cause, it is important to get to the root of the problem so that your pup can lead a happy, healthy life.
