Why Does My Dog Keep Licking His Lips? What Are the Causes and Solutions?

Dogs, like humans, can experience dry mouth. This means that they may lick their lips to try to moisten them. Dogs who stay outside all day long are at risk for dry mouth because there is less humidity in the air.

Dogs also lick their lips when they are nervous or if they have an injury to their mouth that needs to heal. They may also lick their lips if there is a skin irritant on the skin near their mouth.

Signs of this include scratching the area around the mouth and licking the lips compulsively.

Dogs who lick their lips due to dry mouth will usually also salivate excessively, paw at their mouths, and show other signs of discomfort such as eye tearing or squinting.

Why does my dog keep licking his lips?


Many dogs will lick their lips as a means of releasing a stimulus. A lot of the times they will lick them when they are stressed or angry.

They will also lick them when they have something stuck between their teeth.

If they are suffering from food allergies, this may be a sign that they are licking their lips in order to find what they need.

Some dogs are just a bit odd and do not seem to care that they are doing something strange or unusual.

Their owners will find this behavior endearing and will ask the owner if they’re licking their lips in an attempt to scare the child/pet they are petting.

Common reasons why dogs lick their lips?


Dry mouth. A dry mouth is a condition where your dog's mouth is dry and there is not enough saliva. This can be caused by one of three reasons:

Dry air: The outside air temperature is usually much colder than the inside air temperature, so the dog's mouth is dry. This can also be a symptom of frostbite on the dog's muzzle or nose.

The breed can make a difference. Some breeds, like basset hounds, have short muzzles that might not be able to move as much of their dry air away from the mouth.

Sarcoptic mange: Sarcoptic mange is caused by mites that live on the dog's skin. They can cause your dog's skin to become very dry, and the mites can even cause dry mouth symptoms by feeding on the dry dog saliva.

What is dry mouth in dogs?


Dry mouth is usually seen in dogs who spend most of their day outside, are sensitive to changes in humidity, and are not getting regular salivary checkups.

Other possible causes of dry mouth in dogs include allergies and mouth ulcers, which may be present as a result of stress, illness, and exposure to something that irritates the skin around the mouth, such as pepper spray, carpet, or hard surface floors.

When a dog’s mouth is already stressed, licking or licking more frequently can irritate the mouth, even more, leading to a dry mouth.

Dry mouth can also be the result of a tooth infection or gum disease or a disease that impacts the salivary glands in the mouth.

Dogs with excessive saliva are also at risk of dry mouth.


How do I know if my dog has dry mouth?


Dogs who lick their lips due to dry mouth will lick them often to try to moisten them. 

Generally, if your dog is licking his lips, there is a good chance he has a dry mouth.

Dogs who lick their lips due to dry mouth will often lick them for the same reason we do. This is to moisten them in an effort to make them feel better.

Sometimes, the signs of dry mouth can be hard to see because they are only visible to the owner.

If you have a dry mouth and notice your dog licking his lips, it is a good idea to stop, because it could indicate a more serious condition, such as dental disease or eye irritation.

How to stop your dog from licking his lips?

While the reason for dog licking his lips is not known, the most common reason for dogs licking their lips is to moisten their mouths.

Dogs will lick their lips when they feel they are thirsty. You can prevent your dog from licking their lips by providing a bowl of freshwater for them every time they come inside.

Another reason your dog may lick his lips is to treat them. If your dog is not currently eating any food and is just consuming water, she may lick her lips as a signal that she wants to be fed.

By repeatedly giving her the water when she licks her lips, she will eventually associate the mouth-watering with food.

If your dog is underweight, it is possible that she is still hungry, and licking her lips might be her way of signaling that she still needs to eat.


Dogs who lick their lips to moisten their mouth may have an underlying health issue.

A sudden change in eating habits, allergies, illness, stress, or anxiety may also cause a dog to lick his or her lips.

Dogs can lick their lips to make themselves feel more comfortable, more alert, or more at ease. There are multiple reasons why they might do this.

Discuss these findings with your veterinarian to make sure that any changes in your dog's health do not make him or her more likely to lick his or her lips.

Remember, your dog's health is much more important than keeping him or her from licking his or her lips.

Why Do Dogs Put Their Ears Back? (And What It Means)

A common question for animal behaviorists is “Why do dogs put their ears back?” This can be difficult to answer since there are many reasons why this might happen.   It might be because the dog is not comfortable with something or someone, which can indicate fear. The ear posture may also show flattened aggression, where the dog becomes defensive of his territory.   However, it could also mean that the dog is unsure of what you are asking him to do. If your dog has his ears pinned back, then there may be a good chance he is feeling overwhelmed or stressed by the current situation.   Ears can also be used as an indicator of stress or fear.
