Excessive Lip Licking In Dogs โ€“ Should You Be Worried?

Occasional lip licking in dogs is only natural. But when your furry friend takes to licking its lips with an increasing frequency, you need to sit up and pay attention. Now, what are the causes of excessive lip licking in dogs?

The reasons for excessive lip licking in dogs include stress, anxiety, hunger, or an underlying health condition. Excessive lip licking in dogs can also be due to fear, poisoning, or a sign that your pooch is overheating.

The reasons for excessive lip licking in dogs vary greatly. And the ability to distinguish between the various forms of lip licking in dogs is something you should be able to do as a dog owner, as this can significantly impact on your furry friendโ€™s quality of life. Thankfully, this, along with steps to take, when you notice excessive lip licking in your pooch is explained to great detail in todayโ€™s article. However, before we proceed, letโ€™s see why your dog may be licking its lips a lot.

Why Is My Dog Licking His Lips A Lot?

Your Dog May Be Feeling Nauseous

Excessive lip licking, coupled with swallowing is an indicator that a pooch is feeling nauseous. Nausea in dogs typically results in hypersalivation and drooling, and pooches lick their lips to get rid of the excess saliva produced.

Nausea, accompanied by vomiting and licking is usually an indicator of another underlying health condition or poisoning. And if it persists in your pooch for more than 24 hours, then you should schedule an appointment with your vet immediately.

Your Dog May Be Dehydrated

A dehydrated dog will constantly and excessively lick its lips as a way of combating dryness in its mouth or tongue.

Frequent licking in this case is a dogโ€™s way of trying to stimulate its salivary gland, and it can also be a signal to you that a refreshing drink for your dog is long overdue.

Your Dog May Be Suffering From An Underlying Health Condition

The reason your dog is licking its lips a lot, may be due to the presence of an underlying medical condition. Common health issues indicated by a dog licking its lips more often than usual include:

In most cases, excessive lip licking in dogs caused by bloat is usually accompanied by yawning, vomiting, and drooling.

Obsessive-Compulsive Disorder

Dogs, just like humans, can suffer from obsessive-compulsive disorder (OCD). And one of the indicators that your pooch may be suffering from OCD is a tendency to lick its lips more frequently.

OCD in dogs may occur as a result of an illness or stress. And apart from excessive lip licking, this disorder in dogs is also characterized by behaviors such as tail chasing, self-injury, pacing or circling and excessive chewing of an object.

Partial canine seizures affect only a portion of the doggieโ€™s brain, and may be the reason your dog has suddenly taken to licking its lips more frequently.

Lip licking in this situation is typically accompanied by fly biting motions and unusual behavior. And a pooch exhibiting these symptoms should be taken to see a vet as soon as possible.

Other Examples Of Lip Licking

Apart from the health and physical conditions mentioned above, excessive lip licking in dogs can also happen due to:

What Causes Excessive Lip Licking In Dogs?

Stress Or Anxiety

The tongue flip or excessive lip licking is a classic sign of stress and anxiety in doggies. Stress and anxiety can develop in a dog due to an invasion of the canineโ€™s private spacemoving to a new, unfamiliar environment or the introduction of a new baby or pet.

Excessive lip licking, in this case, is the doggieโ€™s means of communicating with its human that itโ€™s uncomfortable with the new changes and a subtle plea to make the cause of stress or anxiety go away.

Attention Seeking Behavior

Dogs may also lick their lips excessively as a way of drawing their ownerโ€™s attention. And this behavior is typically reinforced if youโ€™ve previously given your dog attention when you notice it licking its lips.

Attention seeking by lip licking is commonly observed in pooches that have been left alone at home for a considerable period or in doggies whose owners do not pay enough attention to them.

Possible Effects Of Excessive Lip Licking In Dogs

Excessive lip licking by a doggie may result in inflammation and swelling of the lips and the skin surrounding the mouth; This, in turn, will lead to even more licking of the lips by the Fido in a potentially endless loop.

Inflammation of the lips can also lead to secondary skin infections, and this can degenerate to a chronic skin condition, if left untreated.

Additionally, if the underlying health condition responsible for excessive lip licking in a doggie goes unchecked, it can be potentially detrimental to your furry friendโ€™s health.

How Do I Stop My Dog From Compulsive Licking?

Book An Appointment With Your Vet

After running a series of tests and examinations on your furry friend, the vet will be in a better position to decide whether the cause of your doggieโ€™s excessive lip licking is medical or behavioral.

If the cause of excessive lip licking in your pooch is medical, your vet will prescribe the appropriate medication to treat the underlying health condition. And in the cases of behavior-induced licking, you may need to employ the services of a behavioral trainer for your pooch.

Regular Medical Check-Ups

Taking your pooch for regular medical check-ups may also help prevent the development of various dental issues and digestive conditions typically indicated by excessive lip licking.

Create A Stress-Free Environment For Your Dog

As stated earlier, excessive lip licking can be a sign of anxiety in dogs. And if you want to eliminate this behavior in your pooch, it is your duty as owner to ensure your furry friend is as comfortable as possible.

Start by identifying and eliminating stress triggers in your pooch, and give your pooch the required amount of attention, care and love to prevent development of the obsessive compulsive disorder.

Additionally, exercising can be a great way of reducing stress in your pooch. And you should regularly take time out to engage your doggie in physical activities like walking and playing games like fetch.

When you notice excessive lip licking in your dog, you can try to distract it by offering it either its favorite toy, treats or something else to nibble and chew on, and divert attention away from the lips.

Keep Your Dog Hydrated

Making sure your pooch has constant and regular access to clean, refreshing water will help prevent issues of hypersalivation, and consequently eliminate excessive lip licking.

Why Does My Dog Keep Sticking His Tongue In And Out? When your dog keeps sticking its tongue in and out, it can either be panting to aid with temperature regulation or simply because its jawbone is too small to accommodate the tongue. Additionally, the continuous sticking in and out of tongues in a pooch can be an indicator of oral cancer or any of the various dental diseases.

Are Dog Licks Really Kisses? A dogโ€™s lick can be the equivalent of a human kiss, and pooches typically lick to show affection. However, you should also know that dogs will lick someone who is seemingly agitated as a way to help such a person relieve stress. And if your pooch finds the taste of your skin appealing, then you should be prepared to be on the receiving end of many licks.
