Dog Mouth Warts: Oral Papillomatosis in Pups Explained
Key points
- Oral papillomas are benign warts that can grow around the mouth of young dogs
- They are caused by a virus spread by other infected dogs
- Treatment is not usually required
- These warts usually regress and disappear by themselves over time
- They are not contagious to other animals or humans
Common in
Young dogs of any breed, as well as animals that are immunocompromised
Symptoms & types
Oral papillomas usually appear as grey or flesh-colored lumps around your dogs lips or gums. These lumps are usually small and cauliflower-like in appearance, looking a bit irregular. Your dog may only have one single lump, or they could have multiple. As these masses affect the mucous membranes they may also be seen in other locations around your dogs mouth such as the roof of the mouth, tongue, or back of the throat.
In some rare cases, these papillomas can besevereand extensive. When this occurs dog might have difficulty chewing and swallowing, or even breathing.
Most of the time warts are nothing to worry about. Warty growths around the mouth of a young dog are usually caused by an oral papillomavirus, and the lumps regress by themselves again.
Understanding the diagnostics
Diagnosis of an oral papilloma can usually be made from an examination by a veterinarian. That combined with the location of the wart and the dogs age usually gives a reasonably reliable answer. However, in some cases, the appearance of the growth may not look like a classic papilloma and your vet may need to run some additional tests to be sure.
Removal of the lump under anesthetic can be performed, and the growth can be sent away for analysis (termed an excisional biopsy). This can give a more certain diagnosis in any cases that arent clear cut. However, bear in mind that most oral papillomas will shrink and disappear by themselves without the need for surgical removal.
Learning about the causes
The underlying cause of oral papillomatosis ispapillomaviruses. There are a variety ofdifferent virusesthat can affect dogs, but these are all canine-specific and are not contagious to other species (including humans).
The virus is infectious between dogs, however, and can be spread by direct dog-to-dog contact or through encountering the virus in the environment e.g. shared water bowls. The virus usually enters through small cuts or tiny areas of damage in the dogs mucous membranes. After a few weeks, the growths start to become apparent, usually as warts on your dogs lip or gums, but sometimes they might be seen on the skin too.
Oral papillomas are contagious and can spread by either direct contact with an infected dog or through touching items that an infected dog has touched with their mouths (like toys and food bowls).

In severe cases, the following treatment options might be considered:
- Azithromycin, a type of antibiotic
- Interferon, an anti-viral medication
- Surgery to remove problematic lumps (or cryotherapy freezing warts)
- A canine oral papillomavirus vaccine developed in the US shows some good effects in certain cases.
- Immunomodulating drugs (e.g levamisole and thiabendazole) may be helpful, but more research and evidence are needed.
As oral papillomavirus iscontagiousbetween dogs you should avoid your dog mixing with other young animals, where possible, to stop the spread whilst you wait for the lumps to regress. Keep a close eye on your dogs mouth, in case there are any less obvious warts on the inside of it that are causing problems.
You can support your dog by making sure he is on a good-quality complete diet to ensure his immune system is getting all the nutrients it needs.
Conclusion
Oral papillomas are seen most commonly in younger dogs, appearing as fleshy warts. They are caused by a virus that is contagious between dogs. Most warts will regress and disappear again by themselves without the need for any treatment. However, you should always contact us for an examination if you have any concerns about your pet.
Canine Papilloma Virus: Cause, Treatment & Cost Of Dog Warts

Pro Tip: Although canine oral papillomas are quite common, theres a risk that an undiagnosed lump on a dogs lip could be something more serious. Those enrolled in pet insurance can quickly gain peace of mind by taking their dog to the vet, so they can get the answers they need while knowing any new condition will be financially covered.
What is a papilloma?
A papilloma is a small, benign skin tumor, commonly known as a viral wart. They can occur anywhere on the body including bumps on the eyelid and between the toes but canine oral papillomas specifically refer to warts on a dogs lip, tongue, gums, and other areas around the muzzle.
What does a papilloma look like on a dog?
Canine oral papillomas occur on the mucous membrane of the mouth and typically appear as whitish, grayish, or flesh-colored skin growth. Sometimes, a papilloma looks like a smooth pimple on a dogs lip but most of the time, they have a textured cauliflower appearance.
The virus typically causes clusters of hundreds or even thousands of warts to appear at once, although there are cases where only a single papilloma is present. These abnormal growths can get rather large, ranging from a few millimeters to a few centimeters in size.
Despite their unsightly appearance, the benign tumors are generally harmless but remember that some lumps on dogs skin may be indicative of cancerous growth, so its always important to consult a veterinarian for a proper diagnosis.

What causes viral papillomas in dogs?
Mouth warts on dogs are caused by the oral papilloma virus, otherwise known as oral papillomatosis or canine papillomavirus type 1 (CPV1). This highly transmissible disease causes dogs to acquire warts on their oral mucous membranes. While all dogs can get oral papillomas, its most common in puppies and seniors due to their weakened immune systems.
The oral papilloma virus is present within the wart itself, so the transmission can occur through direct contact and indirect contact with items an infected dog has touched (such as a food or water bowl, toy, or bedding).
Therefore, the risk of CPV1 transmission is significantly higher at dog daycare and breeding facilities where common items are shared. Canine papillomas have an incubation period of one to six months, so if your dog has a mouth wart, it may be difficult to establish when or how they became infected.
Symptoms of oral papilloma virus in dogs
The primary symptom of canine papilloma virus is the appearance of warts around the mouth. Fortunately, dog warts are benign, meaning they do not pose dangerous health risks and will not cause any discomfort unless they become infected.

Most dogs are asymptomatic unless the sores interfere with swallowing or chewing, or the lesions become infected. Infected papillomas can cause swelling, bleeding, bad breath, and pain. Behavioral changes might be noticed if the sores are painful enough to inhibit eating.
In healthy dogs, the majority of mouth warts spontaneously regress and go away on their own within two to three months; surgical excision is rarely necessary. Once a dog has contracted CPV1, they will develop an immunity and its unlikely they will ever develop oral papillomas again.
Dog papilloma stages of development
Pet parents can monitor the development of viral warts through each stage of papilloma growth on dogs.
Stage 1: A small, smooth lesion appears around the mouth and continues to grow or multiply.
Stage 2: The surface of the papilloma becomes texturized with growth.
Stage 3: If an oral papilloma is located inside the mouth and continues to actively grow, dogs might experience discomfort leading to a refusal to eat.

Diagnosing canine papilloma virus
Usually, veterinarians can visually diagnose dogs with canine papilloma virus, as the cauliflower-type warts are easily recognizable. Still, its recommended to have all growths or lumps on or under your pets skin evaluated by a vet. Though some lesions may appear benign, theres always a risk they could be harmful forms of cancer. Based on the lesions appearance, your vet might recommend a biopsy of the skin growth.
How to treat dog warts on mouth
Many pet parents want to know how to get rid of dog warts ASAP, but in most cases, treatment for oral papillom virus is unnecessary because it usually goes away on its own. However, if your dogs mouth warts start to bleed, increase in size, or cause discomfort, your vet might recommend a canine papilloma virus treatment, such as:
Antibiotics
Oral papillomas that become infected by the bacteria living in the mouth will require an antibiotic prescription. However, the medication will not make the appearance of dog warts go away, because antibiotics do not target the virus itself but rather the secondary infection.
Interferon-Alpha
Interferon-alpha is an off-label treatment used to combat severe cases of canine papilloma virus by stimulating an immune response. Its given by mouth or injection two to three times per week, which can quickly become expensive while yielding inconsistent results.
Cryotherapy
If the condition worsens in severity or will not improve on its own, an alternative treatment known as cryotherapy may be recommended to remove dog papillomas by freezing off the tissue growth. Surgical excision may be another option, but it should be considered very carefully if intended for aesthetic purposes alone, as the invasive procedure can result in scarring and lead to secondary health complications.
Topical Cream
Though medical treatment is not necessary for mild cases of canine papilloma virus, a new topical cream can be used to address the aesthetic appearance of dog warts. The ointment is applied directly onto the affected area to boost the skins immune response to inflammation and assist in the destruction of the virus, thereby helping to get rid of papillomas more quickly.
Vaccination
A new vaccine for oral papillomatosis has also been recently developed. Its designed to use the DNA of the virus to generate an immune response, thereby helping to stimulate the canines immune system to remove oral papillomas more efficiently.
Although it is still considered an experimental product, some vets may recommend its usage as a therapeutic vaccine for existing CPV infections, or as a preventative vaccination for puppies. However, there are indications that the vaccine may cause cancer at the injection site in rare cases.
The bottom line: Only a veterinarian can recommend the best treatment for canine papilloma virus for your unique pet based on their unique medical history and individual symptoms. Schedule an appointment with your primary care vet to discuss your options.

Dog papilloma treatment costs
A definitive diagnosis of oral papilloma through biopsy and full histopathology can cost about $500, but the price may increase with the help of a veterinary specialist. Extensive surgical treatment can cost up to $2,500 but in most cases, surgery performed by a general practitioner costs between $300 and $1,000.
Pro Tip: When considering treatment for growths or lumps on dogs skin, many pet parents spend time stressing over potential veterinary costs. Pet insurance is valuable in such instances because it frees you from making an emotional decision based on affordability, rather than your veterinarians recommendation.
How long does it take for dog warts to go away?
In healthy dogs, the lesions caused by oral papilloma will recede within two or three months, and the patient will develop an immunity that will protect them from contracting the virus in the future. If your dog has warts, be sure to limit their contact with other dogs, as the virus is contagious between canines.
Is oral papilloma virus in dogs contagious to humans?
Many pet parents are concerned about whether dog warts are contagious to humans, but the answer is no. The oral papilloma virus in dogs is only transmissable among the canine species.
