Oral Papilloma Virus in Dogs
Your parents probably warned you that kissing a stranger was like kissing everyone that person kissed. Well, they were right and the same advice applies to your dog.
What is papilloma virus?
Canine oral papillomas, also known as oral warts, are small, benign tumors of the mouth caused by the papilloma virus. They are found on the lips, gums, mouth, and rarely can also be located on other mucous membranes.
Causes of papilloma virus in dogs
Canine oral papillomas usually affect young dogs, under the age of 2. Young dogs are more susceptible to the papilloma virus because their immune system is not fully developed. As their immune system matures, they produce antibodies against the virus and the warts can eventually disappear. Affected dogs can transmit the virus to other dogs through direct contact. This usually occurs when they greet each other, share toys, or eat/drink out of the same food or water bowl. Canine papilloma virus is species-specific and therefore cannot be transmitted from dogs to humans or cats.
Symptoms of papilloma virus in dogs:
Papillomas typically develop on the lips, tongue, throat or gums. They are round and have an irregular surface, reminiscent of a cauliflower or sea anemone, and usually grow in clusters. Most dogs are asymptomatic unless the papillomas become infected. Infected oral papillomas can cause pain, swelling and bad breath.
Diagnosis of papilloma virus in dogs:
It is always a good idea to bring your dog to the veterinarian if you ever notice any lump or bump. Your veterinarian can usually diagnose canine oral papilloma by their characteristic appearance. Since oral papillomas can occasionally become malignant (cancerous) and other cancers can grow in the mouth, your veterinarian may obtain a biopsy of the lesion to establish the diagnosis, depending on your pet’s age. Likewise, your veterinarian will examine your dog’s mouth to determine if the papillomas are infected and antibiotics are needed.
