Overview
Scabs on a horse’s skin are often linked to rain scald, but they can also be caused by other skin problems, minor trauma, insect irritation or, less commonly, infection. If the scabs are spreading, very sore, wet, smelly or not improving with normal care, it’s worth looking a little closer.
Things To Check
1. Check where the scabs are. Rain scald often shows up on the back, quarters, rump, neck or other exposed areas that get wet.
2. Look at the pattern. Scabs in lines, patches or under the saddle or rug can point to rubbing, pressure or irritation rather than rain scald alone.
3. Feel for heat, swelling or tenderness. These can suggest the skin is more inflamed than a simple dry scab.
4. Notice whether the skin is dry and crusty or wet and sticky. A moist, greasy or oozing area may need closer attention.
5. Check whether your horse is itching, rubbing or sensitive to touch. That can happen with several skin conditions, not just rain scald.
6. Think about recent changes in turnout, rugs, washing, clipping or grooming. New routines can sometimes trigger skin irritation.
7. Look for any bald patches, broken hair, discharge or a smell. These can suggest the issue is more than simple surface scabbing.
Common Causes
Rain scald is a common cause, especially after wet weather or if the coat stays damp for long periods. It often causes small scabs with matted hair, usually on exposed areas.
Other common causes include rubbing from rugs, tack or mud, mild skin trauma, insect bites and general skin irritation from wet or dirty conditions.
Less commonly, scabs can be linked to bacterial or fungal skin infections, mites or other skin disease. These are more likely if the area is spreading, very itchy, painful or not settling with normal management.
What To Do
Keep the area clean and dry where possible, and avoid picking scabs off. Gentle grooming can help you monitor the skin without making it sore.
Review anything that might be rubbing, such as rugs, tack or wet gear, and make sure turnout and shelter are as sensible as you can manage in the weather.
If the horse is still comfortable, you can keep an eye on the area for a few days to see whether it improves, spreads or becomes more inflamed. Clear photos can help you track any changes.
Products That May Help
