Why is my horse flaky and crusted after being turned out in wet weather?

Overview
Flaky, crusted skin after wet turnout is often linked to rain scald, which is a common skin problem in horses exposed to damp weather. It can also be caused by other skin irritation, so it’s worth checking the area carefully rather than assuming it’s just the weather.
The good news is that many cases are straightforward to manage with sensible grooming, drying, and turnout adjustments. If the skin is sore, spreading, or not improving, a vet may need to look for another cause.
Things To Check
1. Check where the flakes or crusts are appearing. Rain scald often shows along the back, rump, neck, or other areas that stay damp.
2. Look closely for rubbed skin, scabs, redness, swelling, or any discharge under the crusts.
3. Notice whether the coat feels damp for long periods after turnout, especially if the horse has a thick coat or a rug that traps moisture.
4. Think about whether the problem started after a spell of wet weather, muddy turnout, or changes in rugging or grooming.
5. Check if the horse seems itchy, uncomfortable, or sensitive when you touch the area.
6. Look at other horses in the same field or yard to see whether they have similar skin changes.
7. Note whether the issue is mild and localised, or whether it’s spreading and affecting larger areas of skin.
Common Causes
Rain scald is one of the most common causes after wet turnout. It often affects damp, chilled areas of the coat and can leave small tufts of hair, crusting, and flaky skin.
Skin irritation from prolonged wetness, mud, or a rug that stays damp can look similar. Friction from tack, rugs, or grooming can also make the skin appear flaky or crusted.
Less commonly, a bacterial or fungal skin issue, lice, or an underlying skin sensitivity may be involved. These can be harder to tell apart at home, especially if the skin is sore or not improving.
What To Do
Bring the horse in and dry the coat fully if they’ve been out in persistent rain. Avoid leaving damp rugs on for long periods, and make sure anything used next to the skin is clean and dry.
Handle the area gently. Don’t pick at the crusts, as that can make the skin more sore. If the horse tolerates it, soft grooming and careful coat care may help you see whether the skin is settling or worsening.
Review turnout and shelter. If possible, reduce time in wet, exposed conditions and make sure the horse has somewhere dry to stand out of the weather.
Keep an eye on whether the problem improves within a few days of better drying and management. If it’s spreading, becoming painful, or keeps coming back, it’s sensible to get veterinary advice.
Products That May Help
Shampooing and gentle coat care can be useful as part of a routine to help keep the coat clean and make it easier to monitor flaky or crusted areas after wet weather.
