Warts on Horses’ Nose – Causes, Treatment, and Prevention

by | Jul 16, 2023 | Equine Health, Equine Treatment

Just as people can suffer from skin problems, so too can horses. One of the common dermatological issues equine owners often encounter is warts, particularly on a horse’s nose. These small, raised growths are usually harmless but can sometimes be an eyesore and a source of discomfort for the horse. Understanding the causes, treatments, and preventive measures can go a long way toward maintaining your horse’s overall health.

What Are Horse Nose Warts?

Commonly known as equine papillomas, horse nose warts are small, rough, cauliflower-like growths that appear predominantly on the nose and mouth area of young horses, typically under the age of 3. Caused by the equine papillomavirus, these benign growths are the horse’s immune response to this viral infection. While generally harmless, these warts can sometimes cause discomfort, especially when they appear in large clusters.

Causes of Horse Nose Warts

As previously mentioned, horse nose warts are the result of the equine papillomavirus. The virus is highly contagious and can easily spread from horse to horse through direct contact or shared grooming tools, feed buckets, and other equipment. Young horses are particularly susceptible to the virus because their immune systems are still developing, making them less capable of fighting off the infection.

Symptoms and Diagnosis

Equine papillomas are typically easy to diagnose due to their distinctive appearance. The wart-like growths may appear individually or in clusters, mainly on the nose, lips, and sometimes extending into the mouth. They are often grayish-white and have a rough, irregular surface. While they generally don’t cause pain or discomfort, severe infestations can lead to difficulty eating or drinking.

Treatment and Product Recommendations

The good news for owners is that horse nose warts often resolve on their own over time as the horse’s immune system matures and combats the virus. Typically, this process takes a few months, and specific treatments are not usually necessary.

However, if the warts become extensive, causing discomfort or preventing the horse from eating properly, treatment may be required. Salves and creams containing salicylic acid or imiquimod, like Zymox Equine Defense Cream, can be applied topically to stimulate the immune system and accelerate wart regression.

It’s advisable to apply these under the guidance of a vet, and protective gloves should be worn, as these products can be irritating to human skin.


There’s no guaranteed way to prevent equine papillomavirus infection, but there are steps that can be taken to minimize the risk. Ensuring good hygiene and not sharing equipment between horses can limit the spread of the virus. A healthy diet and lifestyle also play a crucial role in building a strong immune system. Supplements like Farnam Vita Plus Balanced Multi-Vitamin & Mineral Horse Supplement, a vitamin-rich supplement designed to boost overall health, can aid in improving the horse’s immune response.

Remember, a robust immune system is the best defense against equine papillomavirus and other diseases. Implementing appropriate preventive measures, maintaining good hygiene, and providing a balanced diet are critical for your horse’s overall health and well-being.


At present, there are no specific vaccines available to prevent equine papillomavirus infection. However, it’s essential to ensure that your horse is up-to-date with all other vaccinations. A comprehensive vaccination program helps bolster the horse’s overall immune function, indirectly aiding in the defense against papillomavirus.


If a horse is diagnosed with warts, isolating it from others can help prevent the spread of the virus. While this may not always be feasible, especially in large stables, it’s advisable to at least separate grooming tools, feed buckets, and other items that the affected horse frequently uses.

Veterinary Care

Even though horse nose warts are typically harmless, it’s essential to have your horse regularly examined by a veterinarian, particularly if your horse’s warts don’t disappear within a few months or if they appear to be causing discomfort. The veterinarian may take a biopsy of the wart to rule out other conditions or to confirm the presence of the papillomavirus.

Promoting Immune Health

Supporting the horse’s immune system is one of the best ways to combat equine papillomavirus. Apart from a balanced diet, various supplements can aid in maintaining a healthy immune system. Products like UltraCruz Equine Vitamin C Supplement, a specially formulated vitamin C supplement, are designed to promote immune health. Similarly, Horseshoer’s Secret Pelleted Hoof & Connective Tissue Supplement can help in overall connective tissue health and resilience.

Maintaining Skin Health

Lastly, taking care of your horse’s skin is also vital in preventing and treating nose warts. A healthy skin barrier can limit the virus’s ability to invade skin cells. Regular grooming using products like Farnam Vetrolin Bath, an equine skin and coat conditioner, can help maintain skin health, reducing the likelihood of skin problems.


Horse nose warts, though common and generally harmless, require an owner’s attention. In most cases, they disappear on their own over time as the horse’s immune system matures. However, in cases where warts cause discomfort or affect the horse’s ability to eat, medical intervention might be necessary.

The best approach towards horse nose warts is a preventive one – maintaining good hygiene practices, providing a balanced diet, using immune-boosting supplements, and ensuring regular vet check-ups. While these warts can be a minor nuisance, with proper care and management, they don’t have to become a significant issue.

As always, consult your vet before starting any new treatment or supplement regimen, and report any changes in your horse’s condition promptly. Your attention and diligence will go a long way in keeping your equine companion healthy and happy.
