Understanding Rain Rot in Horses

Rain rot, scientifically known as Dermatophilus congolensis, is a common skin infection that affects horses and other animals. This condition is caused by bacteria living on the horse’s coat which become active when exposed to moisture from rain or humidity. Symptoms of rain rot are scabs and pus-filled lesions on the horse’s coat, which can be extremely itchy and uncomfortable for the horse.

Understanding the dangers of rain rot

Rain rot can lead to a number of serious health issues if left untreated. The infection can spread quickly and cause increased irritation, inflammation, and pain for the horse. In severe cases, rain rot can cause permanent scarring or hair loss on the affected area. If allowed to progress, the infection could even enter into the horse’s bloodstream causing further issues.

How to spot rain rot on your horse

Inspecting your horse’s coat regularly for any signs of rain rot is important. Look for skin lesions, scabs, or patches of hair loss. It is also important to note that in some cases, rain rot may not be visible until it has been growing underneath the surface of the skin. This is more likely in the cooler months when horses are still in their winter coats. If you notice any suspicious areas on your horse, it is important to contact your vet immediately.

Causes of Rain Rot

The primary cause of rain rot in horses is a bacterium called Dermatophilus congolensis. This bacterium lives dormant on the horse’s skin and becomes active when it comes into contact with prolonged moisture. Moisture can be from rain, high humidity, or even excessive sweating. It’s especially prevalent in warmer climates with regular rainfall. The bacterium then penetrates the outer layer of the horse’s skin, causing characteristic lesions and scabs. Conditions that compromise a horse’s immune system, such as malnutrition, stress, or other illnesses, can also make a horse more susceptible to rain rot.

Write about treating rain rot, include clipping, bathing with antiseptic shampoos, removing the softened scabs, and treating wit antiseptic solutions such as “Fungus Fighter”

If you discover rain rot on your horse, the first step is to remove the source of excess moisture. If your horse is living in a wet environment, you may need to move them to somewhere drier or adjust their shelter so that it provides better protection from the rain.

Clipping and bathing with medicated shampoo is the next step. Many shampoos are available that contain antibacterial agents such as chlorhexidine, which can help keep the infection from spreading. Be sure to read the directions on the shampoo carefully and follow them closely.

After bathing, you will need to remove all of the softened scabs with a soft brush or cloth, taking care not to spread any of the bacteria. So, only use the towel or brush on that particular horse, and dispose after treatment is complete. You can then treat the affected area with an antiseptic solution such as a commercial product like “Fungus Fighter,” or you can make your own by mixing equal parts of water and distilled white vinegar. Allow the solution to dry on the horse’s coat, reapplying once a day until the lesions are healed.

Once the lesions are healed, treating the coat with a moisturizing product such as coconut or mineral oil is important. This will help prevent future outbreaks. Additionally, you should continue to monitor your horse’s environment to ensure that they have adequate shelter and are not exposed to prolonged periods of wetness. By taking these steps, you can help keep your horse healthy and free of rain rot.

It is also important to note that while rain rot can affect horses, it can also occur in other animals, such as goats and sheep. Therefore, it’s important to monitor all of your livestock for signs of infection and take steps to prevent the spread of this disease. Animals can transmit the disease between each other. A healthy coat is an essential part of animal health.


Preventing Rain Rot in Horses

The best way to prevent rain rot is by providing your horse with proper shelter and protection from moisture. Make sure that any blankets or sheets used on the horse are kept clean and dry. If possible, provide a covered shelter for your horse so they do not have to remain in the rain.

In addition, maintain and regularly clean your horse’s brush and grooming tools. This will help prevent bacteria from transferring between horses or animals. If you use shared grooming tools, ensure they are washed with soap and hot water after each use or sanitized with alcohol or an antiseptic. When bathing your horse, avoid using harsh shampoos or other products that can irritate the skin. However, an anti-microbial shampoo after each workout is a useful preventative if this sport or racehorse is continually sweaty or wet.


Rain rot can be a painful and irritating condition for horses. But with proper management, preventing or minimizing the risk of your horse getting infected is possible. This includes providing adequate shelter and protection from moisture and regularly cleaning grooming tools used on the horse.
