Overview
If your horse keeps getting sore scabs after turnout in rain, rain scald is one possible cause, especially if the skin is staying damp for long periods. It can also happen alongside other skin irritation, so it’s worth checking the coat, turnout conditions and whether the skin is getting damaged by mud, rubbing or insects.
Things To Check
1. Check whether the scabs appear after prolonged wet turnout, or whether they’re there even when the horse hasn’t been in rain.
2. Look closely at where the scabs are. Rain scald often affects the back, rump, neck or areas that stay wet under the coat.
3. See whether the skin looks sore, crusty, matted or flaky, and note if there’s any heat, discharge or swelling.
4. Check if the horse’s coat is drying properly after rain, or if the hair stays clumped and damp for long periods.
5. Think about whether rugs, mud, tack or grooming may be rubbing the same areas and making the skin worse.
6. Consider whether there have been recent changes in turnout, field shelter, clipping, coat condition or overall hygiene.
7. Make a note of whether the problem is mild and occasional, or whether the scabs keep coming back in the same spots.
Common Causes
The most common reason is rain scald, which tends to happen when the skin and coat stay wet for too long. Moisture can soften the skin and make it more likely to become crusty and sore.
Rubbing from rugs, tack or headcollars can also irritate damp skin and make scabs look worse.
Mud, dirty turnout conditions and a thick or unclean coat can contribute, because they make it harder for the skin to dry properly.
Less commonly, the issue may be linked to another skin problem, such as an infection, sensitivity or insect irritation, especially if the scabs are spreading or the skin looks very inflamed.
What To Do
Keep a simple note of when the scabs appear, where they are and whether wet weather makes them worse. That can help you spot patterns.
Try to reduce how long the coat stays wet. If possible, give your horse somewhere drier to stand, and check rugs so they fit well and don’t trap moisture or rub.
Keep grooming gentle. If the area is sore, avoid picking scabs off, as that can make the skin more irritated.
Monitor whether the skin improves when turnout conditions are drier, or whether it keeps recurring in the same areas.
If your horse is prone to greasy, dirty or difficult-to-dry skin, a calm washing and coat-care routine can be useful as part of day-to-day management.
