Rain Scald

Rain Scald

Rain Scald is a common problem in horses skin. Also known as dermatophilosis, or rain rot, is caused by the bacterium Dermatophilus congolensis. Mud fever is also caused by this same organism. Thought to originate from the soil, it most commonly occurs in warm moist environments. Rain and higher temperatures encourage the dispersal and penetration of spores into the skin. Ticks, flies and other biting insects also cause the spread of it.  Spread easily from one horse to another, especially if using the same brushes, rugs or blankets.

What does Rain Scald look like?

Typically, it appears in tuft like patches. Once the clumped hair is removed, pus and redness appears beneath the scab. At first, the horse will display a matted coat with bumps, which will then advance to crusty scabs and sores. Usually appearing  on the back and rump, rain scald may also present itself on the back of the fetlock and front of the cannon bone. Except when being removed for treatment these lesions are not painful. Remove any scabs or heavy hair as they protect the organism from oxygen.

How to Treat Rain Scald

Dermatophilus congolensis does not like oxygen. Obviously its important to try and remove the scabs. Malaseb shampoo is a good way to start this process. You shampoo the horse and the shampoo softens the scabs. If you wish you can gently wipe the scabs off with baby wipes. Then apply Good Gear Naturals Stay Put Cream.

The Cream has zinc powder in it which repels water and kills germs. Additionally, zinc toughens the skin. Essential oils also kill the germs. Cold pressed hexane free Castor oil promotes hair regrowth and healing. As well, Stay Put Cream can also be used for Mud fever very effectively. We have had some amazing feedback from clients with severe cases.
