Why Does My Dog Constantly Lick His Lips?

Why Does My Dog Constantly Lick His Lips?… Have you ever noticed your dog licking its lips constantly? It can be disconcerting if you’ve never seen it before, and you may be wondering why your pup is doing it.

In this blog post, we’ll explore some of the possible reasons why your pup might be licking his lips, and what you can do to help.


If your dog is constantly licking his lips, it could be a sign of an allergic reaction. This type of reaction can be caused by exposure to allergens such as pollen, dander, and certain food ingredients.

Allergies in dogs often result in excessive licking of the lips, mouth, or paws, as well as sneezing, coughing, and itching.

If you notice any of these signs, it’s important to speak to your veterinarian right away. Your vet will be able to identify what allergen may be causing the reaction and recommend treatment options.


It’s no surprise that anxiety can affect our canine companions in much the same way as it does us, humans.

Dogs may lick their lips as a sign of fear or nervousness, and it can be triggered by environmental factors such as loud noises or a sudden change in the home. It may also be caused by a traumatic event or experience.

If you think your dog’s lip licking is due to anxiety, it’s essential to identify the source of their stress and try to reduce it.

For example, if your dog is scared of thunderstorms, try creating a safe space and providing them with toys, blankets, and treats to make them more comfortable.

Additionally, try to reward them for positive behaviors and provide mental stimulation activities such as puzzles and training sessions to help keep their mind occupied.

If these methods don’t seem to be helping, you may want to look for the professional help from a qualified animal behaviorist.


Pain is another possible reason why your dog may be licking his lips. Dogs will often lick their lips as a way to relieve pain or discomfort in their mouths or jaw.

This could be caused by an infection, gum disease, toothache, injury, or any other type of oral pain.

In addition, if your dog has a sore throat or any other issue that causes him to experience pain when swallowing, he may also lick his lips in an effort to ease the pain.

If you think your dog’s lip-licking behavior is due to pain, it’s important to have him checked out by a veterinarian. Your vet can check for signs of oral pain or discomfort and prescribe the necessary treatment.

Nausea/Gastrointestinal Issues

Sometimes a dog will lick his lips due to nausea or an upset stomach. If your pup is experiencing stomach discomfort, they may try to relieve their discomfort by licking their lips as a distraction.

If your pup is exhibiting other signs of an upset stomach such as vomiting, diarrhea, loss of appetite, or general lethargy, then you should consult your veterinarian.

They can provide you with a diagnosis and advice on how to best address the issue. Treatment options may include diet changes, medication, supplements, or other therapies.

Dry Mouth

If your dog is experiencing dry mouth, he might be constantly licking his lips as a way to bring relief.

In some cases, dry mouth can be caused by dehydration, so make sure your pup has access to plenty of fresh water and is properly hydrated.

It’s also possible that other health issues, such as liver or kidney problems, diabetes, or cancer can cause dry mouth.

If you think your dog is suffering from any of these issues, it’s important to take him to the vet to get it properly diagnosed and treated.

Additionally, if you suspect that your pup’s dry mouth is due to a certain medication he’s taking, talk to your vet about switching to a different medication.

A dry mouth can be uncomfortable for your pup, so ensure he gets relief as soon as possible!
