What Is Papilloma in Dogs? Causes, Signs & Care (Vet Answer)

Papillomas, also known as warts, are benign tumors that commonly affect dogs. While they can be unsightly and concerning for pet owners, papillomas in dogs are caused by the canine papillomavirus, which is species-specific and not contagious to humans or other animals. In most cases, papillomas will regress on their own without treatment, but it‘s important for dog owners to understand the causes, signs, and care involved with this condition.

What is Canine Papillomavirus?

Canine papillomavirus is a group of DNA viruses that specifically infect dogs. There are several different strains, each tending to target distinct areas of the body. The most common strain is the canine oral papillomavirus, which causes warts to develop in and around the mouth. Other strains may cause papillomas on the skin, eyelids, or genital area.

The virus is highly contagious between dogs and spreads through direct contact with an infected animal or a contaminated object like a shared food bowl or toy. Dogs that are immunocompromised, whether due to age or underlying health issues, are more susceptible to developing papillomas from canine papillomavirus.

Once infected, the incubation period for the virus is typically 1-2 months. After that, warts may appear suddenly and multiply rapidly. The papillomas themselves are usually not cancerous, but they can become irritated, bleed, or become infected.

What Do Papillomas Look Like in Dogs?

Papillomas in dogs typically appear as cauliflower-like growths that are raised from the skin. They can be smooth or rough in texture and range in color from white to pink or grayish black. The size of papillomas varies from small pinhead sized bumps to larger masses up to an inch in diameter.

While papillomas can develop in various locations on the body, they are most commonly found in and around the mouth, including on the lips, tongue, and inside the cheeks or throat. This is why the condition is sometimes referred to as "oral papillomatosis." Papillomas may also appear on the eyelids, paws, or genital regions.

Some dogs may have just one or two warts, while others can develop dozens. Papillomas often grow in clusters and may be shaped like a stalk or dome. If a papilloma is traumatized through scratching or biting, it can become inflamed and infected.

Diagnosing Papilloma in Dogs

In most cases, a veterinarian can diagnose papillomas in dogs with a visual examination. The distinctive cauliflower appearance is often all that‘s needed to identify the growths as warts. However, some vets may recommend further testing to rule out other types of skin tumors or infections, especially in older dogs.

Fine needle aspiration is one diagnostic method in which the vet uses a small needle to collect a sample of cells from the growth. Examining these cells under a microscope can help confirm the presence of papillomavirus, but it‘s not a definitive test. A biopsy, where a piece of the tumor is surgically removed and analyzed, is the only way to get a conclusive diagnosis of papilloma.

Because papillomas are usually benign and resolve on their own, many vets prefer to monitor the growths for changes rather than pursue invasive testing. However, if the papillomas are causing discomfort for the dog or appear to be spreading rapidly, a biopsy may be recommended.

Treatment and Care for Dogs with Papillomas

In most cases, papillomas do not require treatment and will regress within 1-5 months as the dog‘s immune system mounts a response against the virus. This is especially true for oral papillomas in young dogs. As long as the warts are not impacting the animal‘s quality of life, the best approach is usually to simply wait for the virus to run its course.

However, some dogs may need intervention to treat their papillomas. If the growths are very large or numerous, they can interfere with eating, breathing, or vision. Papillomas on the feet can make walking painful. Warts that become traumatized and infected may require antibiotics or anti-inflammatory medications.

Severe cases of papillomas that are not regressing on their own may need to be surgically removed. Cryotherapy, which involves freezing off the growths with liquid nitrogen, can also be effective. Some veterinarians may prescribe immunotherapy in the form of an auto-vaccine made from the dog‘s own papillomas or the oral drug Azithromycin to help stimulate the immune response against the virus.

It‘s important to note that removing the papillomas does not address the underlying viral infection. Even if the tumors are successfully treated, the dog may develop new papillomas until their immune system suppresses the virus completely.

Preventing Papilloma in Dogs

Because canine papillomavirus is so contagious between dogs, preventing transmission of the virus is key to reducing the incidence of papillomas. Puppies and dogs with immature or suppressed immune function are most at risk for becoming infected and developing warts.

Some strategies for papilloma prevention include:

- Minimize direct contact with dogs that have visible warts or are known to be infected with papillomavirus
- Avoid dog parks, kennels, or other locations where many dogs congregate and share items like toys and bowls
- Regularly disinfect shared objects and environments with diluted bleach solutions
- Consider vaccinating dogs against papillomavirus, especially if they are at high risk for exposure

It‘s important to remember that while unsightly, papillomas are usually harmless and self-limiting in dogs. Getting infected is not a sign of poor care or hygiene. Even well-cared for dogs from clean environments can contract the virus.

When to Seek Veterinary Care

While most cases of papillomas in dogs do not require treatment, there are certain signs that indicate a dog should be seen by a veterinarian. These include:

- Difficulty eating, drinking, or breathing due to oral papillomas
- Papillomas on the eyelids that are irritating the eyes or impacting vision
- Warts that are bleeding, oozing pus, or appear infected
- Rapid spread of papillomas or growth of very large masses
- Persistence of papillomas for longer than 5 months
- Any other symptoms of illness like lethargy, fever, or appetite changes

A vet can determine whether treatment is necessary to shrink or remove the papillomas or address secondary issues like infection. They may also want to do additional testing to confirm the diagnosis or rule out conditions like cancerous skin tumors.

The Key Takeaways

Papillomas are warts that commonly affect dogs, especially puppies and those with weakened immune systems. They are caused by the canine papillomavirus, which is highly contagious between dogs but not transmissible to humans or other species. While papillomas are usually benign and resolve on their own within a few months, they can sometimes require medical intervention.

Recognizing the classic cauliflower-like appearance of papillomas and understanding how the virus spreads can help dog owners prevent transmission and monitor their pets for any signs of complications. Working closely with a veterinarian is the best way to ensure a dog with papillomas gets the appropriate care and treatment.

With proper management and time, most dogs with papillomas recover fully. While dealing with warts is never fun, the good news is that canine papillomavirus rarely causes any lasting effects and can be prevented through good hygiene and limiting contact with infected animals.
