Dog Warts: What Every Pet Parent Should Know
Can Dogs Get Warts?
Yes, dogs can get warts — and while they may look alarming, they are usually harmless. Dog warts are small, non-cancerous growths caused by a virus that affects canines. They are most common in puppies and younger dogs whose immune systems are still developing, though older dogs can also be affected. These warts often appear suddenly and may multiply before eventually fading away on their own.

The Symptoms of Dog Warts
Dog warts can show up in different ways depending on your pet’s age, health, and the location of the growths. Some of the most common signs include:
-
Small, rough growths: These warts often resemble tiny cauliflower-like bumps with a rough texture. They may start small and gradually grow larger over time, sometimes becoming more noticeable to the touch before they’re easy to see.
-
Common locations: Warts usually appear on areas where the skin is exposed, such as the mouth, lips, eyelids, nose, or muzzle. They can also develop on the feet, particularly between the paw pads or around the toes, where they may cause irritation when walking.
-
Clusters or multiples: Some dogs develop only one or two warts, while others may experience clusters of growths in the same area. In severe cases, dozens of warts can appear, especially in younger dogs with weaker immune systems.

-
Discomfort or irritation: While most warts are harmless and painless, their location matters. Warts in the mouth may cause drooling or difficulty eating, while those on the paws can make walking uncomfortable. Dogs may lick or chew at irritated warts, which can worsen the problem.
-
Visible changes: A healthy wart is usually stable in size and appearance, but if one becomes red, swollen, starts to bleed, or develops pus, it could mean infection. These changes should be addressed by a veterinarian to rule out more serious issues.
What Causes Dog Warts?
-
Canine Papillomavirus (CPV): This virus is the direct cause of dog warts. It infects the skin and mucous membranes, leading to growths that resemble small cauliflower-like bumps. Different strains of the virus can target specific areas, such as the mouth, eyelids, or paws.
-
Direct Dog-to-Dog Contact: Warts often spread when dogs interact closely, especially during play or grooming. A simple lick, nip, or scratch can transfer the virus if one dog already carries it.
-
Shared Items: Communal use of food and water bowls, chew toys, or grooming brushes can carry the virus from one dog to another. Even visiting dog parks or kennels increases exposure, since many dogs share the same environment.

-
Age and Immature Immune Systems: Puppies under two years old are the most at risk. Their immune systems are still developing, making it harder for them to fight off infections, so warts appear more frequently in this age group.
-
Weakened Immunity in Adults: Senior dogs or dogs with chronic illnesses, such as Cushing’s disease or cancer, may be more susceptible. Medications that suppress the immune system can also increase the likelihood of wart development.
-
Stress and Poor Hygiene: Stressful living conditions, overcrowded spaces, or lack of regular cleaning can weaken a dog’s ability to resist infections. Dirt and bacteria on the skin can further irritate the area, allowing the virus to take hold more easily.
How to Treat Dog Warts?
Most dog warts don’t require treatment and will often shrink or disappear naturally within two to three months as the dog’s immune system builds resistance to the virus. Still, some situations call for closer attention and care:
-
Monitoring at Home: Regularly check the size, shape, and number of warts. Take note if they change color, grow rapidly, or begin to spread, as this could indicate irritation or infection. Keeping a photo log can help track changes over time.
-
Veterinary Care: If a wart becomes painful, starts to bleed, shows signs of infection, or interferes with normal activities like eating, chewing, or walking, it’s best to see your vet. They can confirm whether the growth is a wart or another type of skin condition, such as a tumor.

-
Treatment Options: Depending on severity, vets may recommend surgical removal, cryotherapy (freezing the wart), or laser therapy. These procedures are typically quick and effective. In rare cases, oral or topical medications may be prescribed to speed healing or manage underlying issues that weaken the immune system.
-
Dog Clothes for Protection: If warts are located in areas prone to friction—such as the belly, chest, or legs—lightweight dog shirts or recovery suits can protect them from scratching, licking, or further irritation. This not only prevents discomfort but also reduces the risk of secondary infections.
-
Avoid Human Treatments: Over-the-counter wart removers made for humans often contain chemicals that are toxic to dogs. Using them can burn or damage your dog’s skin, so always stick to treatments recommended by your veterinarian.
Should You Worry About Dog Warts?
Most of the time, dog warts are nothing to panic about. They may look strange, but they’re a normal part of many dogs’ lives and often go away on their own. That said, it’s always best to check with your vet if you notice new growths, changes in appearance, or signs of discomfort. With a little patience and proper care, your dog can stay healthy and happy — bumps and all.
