Overview
If your horse’s scabs keep coming back in winter, the first things to check are moisture, rug rubbing, mud, and whether the skin is staying damp for long periods. Rain scald is one possible cause, but similar-looking scabs can also come from irritation, poor coat condition, or a skin infection. A few practical checks at home can help you spot patterns and decide what to change next.
Things To Check
1. Check whether the scabs are in the same places each time, especially along the back, rump, neck or where a rug sits.
2. Look at whether the skin is staying wet for long periods after turnout, washing, rain or sweating under rugs.
3. Feel for heat, tenderness, swelling or broken skin around the scabs.
4. Check for rubbing from rugs, tack, straps or mane and tail management.
5. Look at the coat for dullness, matted hair, areas of hair loss or scurf.
6. Consider whether muddy fields, poor drying conditions or limited shelter are making the problem worse.
7. Notice whether the scabs seem to be spreading, oozing or becoming more uncomfortable.
Common Causes
Rain scald is a common winter cause, especially where the coat stays damp and the skin becomes irritated. Rubbing from rugs or tack can also create repeated scabs in the same spot.
Less often, ongoing scabs may be linked to bacterial skin infection, lice, mites, or a coat and skin condition that makes the horse more prone to irritation. Sometimes there’s more than one factor at play, which is why checking the pattern matters.
What To Do
Start by keeping the affected skin as dry as practical and avoid unnecessary washing, as frequent wetting can make some cases harder to settle. Check rugs daily so they fit well, stay dry and don’t rub in one place.
Remove loose mud and dirty grease gently, and use a calm grooming routine so you don’t lift scabs off unless they are already loose. If the horse is turned out in wet weather, try to improve shelter, drying time and rug changes where possible.
Keep a simple note of where the scabs are, what the weather was like, and whether they appeared after turnout, grooming or rugging. That pattern can be really helpful if the problem keeps returning.
If the skin is broken, painful or spreading, or if the scabs keep coming back despite sensible changes, it’s worth asking your vet to take a look.
When To Contact A Vet
Contact your vet if the scabs are spreading, the skin is sore or swollen, there’s discharge, your horse seems uncomfortable, or the problem keeps returning despite keeping the area dry and reducing rubbing. Recurrent winter scabs can sometimes need a closer look to rule out infection or other skin issues.
