How I Treated My Dog’s Mouth Wart Naturally

A few years ago, I noticed a small bump on our dog’s mouth - or lips (do dogs even have lips?). At first, I thought it was just a pimple, but it kept growing. After consulting with Google (as one does) and then my veterinarian, I learned it was a canine papilloma - basically, a wart caused by a contagious virus.

I wanted to clear it up naturally if possible - and after successfully doing this twice (with two different dogs), I’m sharing exactly what worked for us. Each time, the wart disappeared within about a month.

Canine papillomas are small, benign growths caused by the canine papillomavirus (CPV-1). These viral warts are most common in:

They typically look like:

These warts are contagious to other dogs but not to humans or cats, and the virus can survive for weeks on shared objects like toys or food bowls.

Although harmless in most cases, papillomas can:

Two of my dogs developed them on their mouths (they played together daily, so it wasn’t a surprise) - and while I didn’t isolate them (impossible in our house), I focused on boosting their immune systems and supporting healing naturally.

The virus tends to affect dogs whose immune systems are temporarily weakened due to:

Essentially, papillomas are a signal - your dog’s immune system could use some extra support.

Veterinarians may recommend:

Because Apollo’s wart was small and he wasn’t bothered, I chose to go the natural route first.

(Note: I’m not a veterinarian. This is what worked for my dogs - always consult your vet before starting new treatments.)

An essential oil blend that helps dry out and remove warts naturally. I applied one small drop directly on the wart once daily. It smells strong and tastes unpleasant (so your dog may lick), but one bottle treated two dogs easily.

Within two weeks, the warts began shrinking and dried up completely by week four.

Colloidal silver acts as a natural antiviral and antibacterial. I sprayed it once daily (opposite time of day from the Naturasil) to reduce viral load and prevent infection.

Since my dogs share bowls, I also added a small amount to their water to help protect everyone from exposure.

Coconut oil is a powerhouse - antibacterial, antifungal, and antiviral. After the silver spray dried, I gently applied a small dab to the wart area to moisturize and support healing.

I’ve been cautioned that using coconut oil or salves can trap moisture and make certain skin issues worse, so I always make sure the area is completely dry before applying anything.

Papillomas thrive when the immune system is weak - so I addressed that too. The supplement I used is no longer available. Today, I would use a holistic supplement formulated to support the immune system. Currently, I use the following:

After the warts cleared, I continued using the supplements four days a week, along with fermented fish stock for gut support. Today, I use Fish Jiggles by Solutions Pet Products.

Here’s what I suggest:

✅ Skip playdates, daycare, and grooming until it’s cleared.
✅ Disinfect shared bowls, bedding, and toys.
✅ Monitor the wart for size or color changes.
✅ Boost the immune system through nutrition and supplements.

The virus won’t spread to you, but it can easily spread to your other dogs - so prevention and hygiene are key.

Your dog’s gut health is directly tied to their immune health. Around 70% of the immune system lives in the gut, so a healthy diet makes a huge difference.

A balanced raw or home-cooked diet supports gut bacteria, reduces inflammation, and helps the body naturally fight off viruses like CPV-1.

Low-glycemic, antioxidant-rich veggies like kale, zucchini, broccoli, and red bell peppers nourish the gut microbiome and strengthen immune response.

Fish Jiggles (by Solutions Pet Products), kefir, and fermented veggies feed good bacteria that crowd out pathogens and boost immune cell production. I don’t suggest fermented foods for dogs with a history of histamine overload or allergies.

Rotate in:

Both Apollo and Scout’s warts were completely gone within 30 days.
No scarring. No recurrence. No spread.

Since then, I’ve continued feeding my dog a nutrient-rich raw diet with immune support, and (knock on wood) we haven’t seen another wart since.
