Overview
If your horse has rain scald, the safest thing to put on the skin is usually something gentle, clean and non-irritating, such as a mild equine wash used carefully, then dried thoroughly. Avoid putting on oily, perfumed or harsh products unless your vet has advised them, because they can sometimes make skin stay damp or become more irritated.
Rain scald, also called rain rot, can have several causes, including prolonged wet weather, a dirty or damp coat, reduced skin barrier comfort, or skin that’s already sore from rubbing or mud. The aim at home is to keep the area clean, dry and monitored while you watch for changes.
Things To Check
1. Check whether the coat has stayed wet for long periods after rain, turnout or washing.
2. Look closely for scabs, matted hair, tenderness, redness, heat or any discharge.
3. Check if the sore patches are in areas that trap moisture, such as the back, rump, saddle area or under the mane.
4. Note whether the horse seems uncomfortable when being groomed or touched over the area.
5. Look at the stable, turnout and rugging setup to see if dampness or mud is likely to be lingering against the skin.
6. Check whether any recent washing, sweating, clipping or rug changes may have left the coat harder to dry.
7. Watch for spread of the patches over a day or two, or for the skin looking more sore rather than less.
Common Causes
The most common reason is skin that has stayed damp for too long, especially in wet, cool weather. That can allow the coat and skin to become irritated and scabby.
Dirty coats, sweat that hasn’t been dried off properly, or rugs that trap moisture can also contribute. Some horses are simply more prone to skin irritation when the weather changes.
Less commonly, the skin may be reacting to another issue such as rubbing, underlying dermatitis, or a different skin infection that looks similar at first glance.
What To Do
Start by gently removing loose dirt and damp from the coat. If you wash the area, use lukewarm water and a mild wash only if needed, then dry the skin thoroughly afterwards.
Avoid scrubbing scabs off. That can make the skin more sore and may slow the area settling. If hair is matted, soften it carefully rather than pulling at it.
Keep the horse as dry as you can, including the coat, stable bedding and rugging. If turnout is very wet or muddy, reducing exposure where possible may help the skin recover.
Monitor the area daily for spread, discharge or increasing soreness. If it’s not improving, or if your horse seems more uncomfortable, it’s sensible to get veterinary advice.
