Springtime is here, which means rain AND rain rot. Rain rot, also known as dermatophilosis, is a common skin infection that affects horses, especially in humid or wet climates. If you've noticed scabby lesions or patchy hair loss, your horse might be suffering from rain rot.
Understanding what causes it, how to prevent it, recognizing the symptoms, and finding the best treatments is crucial for your horse’s health and comfort.
What Causes Rain Rot on a Horse?
Rain rot is caused by a bacterium called Dermatophilus congolensis. It thrives in moist, warm environments. When your horse’s skin stays damp for extended periods, whether from rain, sweat, or even heavy dew, it becomes a perfect breeding ground for infection.
Common causes of rain rot in horses include:
- Prolonged exposure to rain or wet conditions
- High humidity environments
- Lack of grooming or dirty coats
- Sharing contaminated tack, brushes, or blankets
- Small skin abrasions or weakened skin barriers
- Weakened immune systems
Minor skin abrasions allow bacteria to penetrate, leading to the characteristic scabs and hair loss associated with rain rot in horses.
What Are the Symptoms of Rain Rot in Horses?
Identifying rain rot early helps prevent it from spreading or worsening. Here are the most common symptoms of rain rot:
- Crusty scabs and lesions, often raised
- Hair loss in small patches, typically where scabs form
- Matted hair that may look clumpy or tufted
- Red or irritated skin underneath scabs
- Sensitivity to touch in affected areas
- Lesions commonly appear on the back, rump, and legs
If you notice these signs, it is essential to initiate rain rot treatment promptly.
How to Prevent Rain Rot in Horses
Rain rot prevention starts with proper management practices. Here are key steps you can take:
- Keep Horses Dry: Always provide shelter during rain and wet weather. Using waterproof, breathable horse sheets can help protect the skin.
- Groom Regularly: Daily grooming removes dirt, debris, and moisture that can promote bacterial infections.
- Use Antibacterial Products: Sprays and shampoos designed for antibacterial protection can significantly lower the risk.
A wise choice for prevention is a high-quality rain sheet, such as the StormShield II Turnout Sheet, which offers excellent waterproof coverage without overheating your horse.
How to Treat Rain Rot in Horses
Effective rain rot treatment for horses involves several important steps:
- Gently Remove Scabs: Use a soft curry or fingers to gently lift scabs without tearing healthy skin.
- Wash with Antibacterial Shampoo: Bathe your horse with a medicated shampoo like the Ultra® Medicated Shampoo to kill bacteria and clean the skin.
- Dry Thoroughly: After bathing, thoroughly dry the horse to prevent reinfection.
- Apply Antibacterial Spray or Lotions: Products like Equiderma Skin Lotion promote healing and provide a protective barrier.
