January 24, 2019 4 min read

Freezing Temps. Endless Snow. Icy Pasture. Rain Rot.

Treating rain rot on horses in the winter can be a struggle, but not anymore! WATCH as COAT DEFENSE® daily PREVENTATIVE POWDER takes it off INSTANTLY!

What is Rain Rot in horses?

Rain rot shares comes from a bacterium called dermatophilus congolensis. This bacteria is in a family called actinomycetes, these little things act like both bacteria and fungi. Horses naturally have these organisms on their skin; they lay dormant until rainy, wet conditions cause it to flare-up.


We LOVE it!! It cleared up Gidget’s rain rot super fast! We’ve been using the powder as a preventative on Gidget’s back after rides and it has really kept the rain rot at bay. So it’s worth the purchase!

How do you treat rain rot in winter?

The solution to starving off this bacterium is keep your horse’s skin dry. One option is keeping your horse inside. But this simply isn’t an option for some horses. Another way to keep your horse dry is to use a turnout sheet. But this can trap moisture and could actually fuel the bacteria. Winter makes wet treatments for rain rot particulary difficult due to freezing temps.

So, we need to keep our horse’s skin dry, but how?

That’s where COAT DEFENSE® daily PREVENTATIVE POWDER comes in.

Coat defense powder is wonderful! Last year it was a very rainy season the rain rot was bad! My vet said to remove the scabs and let it dry out. It didn’t work and it hurt him pulling off the scabs. Then this year I came across coat defense powder it killed the fugues quickly! Now I use it daily as a preventative treatment and it keeps it away. He also had scratches on his feet vet gave me antibiotic ointment that didn’t work so I tried the drying paste over night it dried up! I highly recommend these products! They are excellent!

I absolutely love this product. I use it in between baths, after riding to absorb sweat, to treat and prevent sweet itch on my sensitive horses, in the winter as a bathing alternative, and as a daily preventative and to treat / prevent scratches on my feathered horses. You can use this product for both dogs and horses with ease. The light mint scent is pleasant. It is a staple in my training program and my Great Danes love it too ! I do not go anywhere without it and I always have my tack room stocked!
