Overview
Call the vet if your horse’s rain scald is spreading quickly, looks painful, is oozing, smells bad, or doesn’t start to improve after you’ve dried the skin and managed the wet conditions. Most mild cases are linked to prolonged damp weather and can settle with better turnout and gentle skin care, but similar looking scabs can also be caused by other skin problems.
Things To Check
1. Check whether the scabs are limited to one area or spreading along the back, rump, neck or shoulders.
2. Look for broken skin, discharge, crusting, swelling, heat or obvious soreness when you touch the area.
3. Notice whether your horse seems itchy, uncomfortable when groomed, or sensitive to rugs, tack or brushing.
4. Think about recent weather and turnout, especially long periods of rain, mud, humidity or a damp rug.
5. Check whether the hair is lifting in tufts or whether scabs are coming away with a little hair attached.
6. See if any other horses in the yard have similar skin changes, which may help narrow down whether it’s a shared environmental issue.
7. Note how long it’s been there and whether it’s getting better, worse or staying the same after basic care.
Common Causes
Rain scald is often linked to wet, humid conditions that leave the skin soft and vulnerable. It commonly affects horses that are out in persistent rain or wearing damp rugs for long periods.
Other skin issues can look similar, including bacterial skin infections, fungal problems, insect irritation or rubbing from tack and rugs. Less commonly, the skin may be reacting to an underlying health issue that needs a vet to assess.
What To Do
Move your horse into a dry, well-ventilated place if possible and keep the affected skin as dry as you can. Gently remove surface mud and loose scabs only if they lift away easily, but don’t pick or scrub at the skin.
Check rugs for dampness, rubbing and cleanliness, and avoid putting a wet rug back on. If turnout is still needed, try to reduce time in persistent rain or muddy conditions where you can.
Keep an eye on the area over the next few days. If it’s improving, that’s reassuring. If it’s spreading, becoming sore or not changing with sensible care, speak to your vet for advice.
When To Contact A Vet
Contact your vet if the skin is very sore, hot, swollen or oozing, if your horse seems unwell, or if the problem is spreading despite keeping the area dry. You should also get advice if you’re unsure whether it’s rain scald or something else, or if your horse keeps getting repeat episodes.
Products That May Help
A gentle wash routine can be useful when you’re managing a horse with rain scald, especially if you need to clean muddy or sweaty coat areas without being too harsh on the skin.
