1. Thirsty

It could be that your dog is thirsty and is trying to signal to you that he needs a drink. Dogs can also start licking their lips when they smell something they like, such as food. If your dog is anxious or stressed, he may also lick his lips to calm himself down.
If your dog’s lip-licking becomes excessive or interferes with his normal activities, it could be a sign of a medical condition, and you should take him to the vet for a check-up. In the meantime, make sure your dog has access to fresh water and provide him with plenty of opportunities to relax and socialize.
2. Feeling Hot
Another common reason for your dog’s lip-licking is because of oral discomfort. When dogs get too hot, they start to pant to cool down. Panting helps to circulate air through your dog’s mouth and evaporate the saliva on their tongues, which helps to lower their body temperature.
If your dog licks his lips, it could signify that he is too hot and needs to cool down. You can help your dog cool down by giving him a drink of water, spraying him with cool water, or taking him to a shady spot. If your dog’s panting and lip licking behaviour become excessive, it could be a sign of heatstroke, and you should take him to the vet immediately.
3. Feeling Nervous Or Anxious
Dogs can also start licking their lips when they feel nervous or anxious. This is often caused by fear or stress, such as during a thunderstorm, fireworks, or meeting new people or animals. If your dog is behaving like this because he is anxious, you can try to calm him down by speaking in a soothing voice and offering him a treat. You should also avoid punishing your dog for being anxious, as this will only make the problem worse. If your dog’s anxiety is severe, you may need to take him to the vet for treatment.
4. In Pain
Another reason for your dog’s lip-licking behavior might is he may be in pain. This could be due to an injury, kidney disease, or dental problem. If you think your dog is acting like this because he is in pain, you should take him to the vet for a check-up.
5. Feeling Itchy
If your dog is constantly licking his lips and scratching his skin, it could be a sign that he is itching. Dogs tend to get itchy for various reasons, such as allergies, parasites, or dry skin. If your dog is itchy, you should take him to the vet. The vet will be able to identify the cause of the itchiness and prescribe the appropriate treatment.
6. Sneezing
If your dog is sneezing and licks his lips, it could signify that he has an allergy or a cold. Allergies are a common cause of sneezing and licking in dogs, especially if exposed to dust, pollen, or other irritants. If your dog has a cold, he may also have a fever, runny nose, and watery eyes. If you think your dog might have an allergy or a cold, you should take him to the vet for a check-up.

7. Drooling
Drooling is normal for dogs, but excessive drooling can signify an underlying medical problem. If your dog is drooling and licks his lips more than usual, it could be a sign of an infection, a foreign body in the mouth, or an allergic reaction. If your dog is drooling excessively, you should take him to the vet for a check-up.
8. Has Gastrointestinal Problems
Dogs can show excessive licking when they have gastrointestinal problems, such as nausea, indigestion, dental disease, or an upset stomach. If your dog licks his lips excessively and seems in pain or discomfort, you should take him to the vet for a check-up.
9. Getting Older
As dog’s age, they can start to experience a decline in their sense of smell. This can lead them to lick their lips more often, trying to taste what they are smelling. If your dog is getting older and licks his lips more than usual, you should take him to the vet for a check-up.
10. Your Dog Has Cancer
In some cases, excessive lip-licking can be a sign of cancer. If your dog licks lips and has other symptoms, such as weight loss, lethargy, or appetite changes, you should take him to the vet.
Best Home Remedies

You can do a few things to help your dog’s behavior due to a medical problem. If your dog is itchy, you can give him a bath with oatmeal shampoo, which will help to soothe his skin. If your dog is drooling excessively, you can try giving him ice chips or frozen carrots to lick. If your dog is anxious, you can try using a calming supplement or giving him a safe place to hide, such as a crate. If your dog is in pain, you can give him over-the-counter medication, such as ibuprofen or acetaminophen.
When to See the Vet
If your dog licks his lips and cannot identify the cause, you should take him to the vet. The vet will be able to perform a physical examination and run tests, if necessary, to determine the cause of the problem. In some cases, such as when a foreign body is stuck in the mouth or infected, treatment will be necessary. In other cases, such as when the licking is due to anxiety or getting older, the vet may recommend some home remedies.
Conclusion
Dogs lick their lips for various reasons, some of which are due to medical problems. If your dog enjoys licking his lips more than usual, you should take him to the vet for a check-up. The vet will be able to identify the cause of the problem and prescribe the appropriate treatment.
