What should I do if my horse has rain scald on its back?

Read time: 3 minutes

Overview

If your horse has rain scald on its back, the main things to do are keep the coat as clean and dry as you can, avoid irritating the affected skin, and monitor whether it’s getting better or spreading. Rain scald often follows prolonged wet weather, but other skin problems can look similar, so it’s worth checking the pattern carefully.

Things To Check

1. Check whether the scabs or matted areas are only on the back and rump, or whether they’re appearing elsewhere too.

2. Look for broken skin, redness, swelling, heat, discharge or an unpleasant smell.

3. Note whether the horse seems bothered by it, such as flinching, rubbing or being sore to groom.

4. Think about recent weather, turnout, rug use and whether the coat has stayed damp for long periods.

5. Check if there’s been any recent clipping, sweating, muddy turnout or heavy grooming that could have irritated the skin.

6. Make sure you’re not seeing lice, fungal skin disease or rubbing from tack, as these can sometimes be mistaken for rain scald.

7. Watch whether the patches are improving, staying the same or becoming more widespread over a few days.

Common Causes

Rain scald is commonly linked to prolonged wet conditions, especially when the coat stays damp and the skin becomes irritated. It can also be made worse by mud, sweat, poor drying after washing or rugs that trap moisture.

Sometimes similar scabs or skin changes are caused by other issues such as fungal skin disease, lice, rubbing, or general skin sensitivity. That’s why it helps to look at the whole picture rather than assuming it’s only rain scald.

What To Do

Start by gently removing loose mud or debris and keeping the affected area as dry as possible. Avoid harsh scrubbing or picking at the scabs, as that can make the skin sorer.

If the horse is out in wet weather, review rug fit and turnout routine so the back isn’t staying damp for long periods. If you’re washing the area, use mild grooming and make sure the coat is fully dried afterwards.

Keep an eye on whether the skin is settling, and note any change in spread, soreness or discharge. If the problem is mild, a steady routine of drying, gentle care and reducing wet exposure may help support recovery.
