What is rain rot in horses?

Rain rot, also known as rain scald or dermatophilosis, is a common skin condition that affects horses. It is caused by the bacteria Dermatophilus congolensis, which thrives in warm, moist environments. Rain rot is most commonly seen in horses that are exposed to prolonged periods of wet weather, such as continuous rain or high humidity.

Symptoms of rain rot typically include small scabs or crusts that form on the horse's skin, most commonly on the back, neck, and hindquarters. These scabs may be itchy and painful for the horse, and if left untreated, can lead to hair loss and further skin irritation.

Treatment for rain rot usually involves keeping the affected areas clean and dry, removing scabs gently, and applying topical treatments such as medicated shampoos or ointments. In severe cases, a veterinarian may prescribe oral or injectable antibiotics to help clear up the infection.

Prevention of rain rot involves keeping your horse dry and clean, especially during wet weather. Providing proper shelter, regular grooming, and keeping turnout areas well-drained can help reduce the risk of rain rot. Additionally, maintaining a healthy diet and proper hygiene practices can also help prevent the condition.
