🌧️🐴 From Drought to Downpours — Horse Owners, Watch Out for Rain Rot!
Here in Southwest Colorado, we've been dealing with severe drought conditions for as long as many of us can remember. Now, we're experiencing record rainfall, and while the moisture is certainly welcome, it brings some challenges we're not accustomed to dealing with.
One of those challenges is rain rot in horses.
Rain rot is a bacterial skin infection that thrives in prolonged wet conditions. When horses are constantly exposed to moisture and their coats don't have a chance to dry out, they become more susceptible.
What to watch for:
🐎 Small, crusty bumps beneath the hair
🐎 Scabs that pull away with tufts of hair
🐎 Patchy hair loss, particularly along the back, rump, and neck
🐎 Tender or irritated skin
How to prevent and manage it:
✅ Provide shelter and opportunities for horses to dry out.
✅ Regularly check beneath their coats for bumps and scabs.
✅ Treat affected areas with an appropriate veterinary antiseptic, such as chlorhexidine shampoo, following product directions.
✅ Avoid forcibly removing scabs that are firmly attached.
✅ Clean grooming equipment and avoid sharing brushes between affected horses.
✅ Contact your veterinarian if the infection becomes severe or isn't improving.
After years of drought, most of us aren't accustomed to managing horses through weeks of continuous rain. Our horses aren't necessarily accustomed to it either!
While we're grateful for the moisture, it's important to recognize that these changing conditions can create new challenges for livestock owners.
🐴 Fellow horse owners, are you starting to see rain rot with all this moisture? What have you found works best for preventing or treating it?
Let's share some experience and help each other out!
