Why does my horse have rain scald on its neck and shoulders?

Read time: 3 minutes

Overview

Rain scald on the neck and shoulders is often linked to prolonged wet weather, a damp coat, or skin that’s staying wet for too long. It can also be associated with skin irritation or a lowered ability of the coat to cope with moisture, so there may be more than one possible cause.

It’s usually worth checking the pattern, the weather, and whether the horse has been left wet after turnout, exercise or washing. That can help you work out what’s most likely and what may need changing.

Things To Check

1. Check whether the scabs or crusting are mainly on the neck, shoulders or back, and whether they seem to match the areas most exposed to rain.

2. Look for patchy hair loss, raised scabs, damp skin, redness, or soreness when you run your hand over the area.

3. Notice whether it’s happening after wet turnout, being rugged, clipping, washing, or exercise.

4. Check whether the horse is spending long periods in rain, mud, or a damp stable, or has a coat that stays wet for a long time.

5. Consider whether there are flies, rubbing, or other skin irritation alongside the rain scald.

6. See whether the horse seems comfortable or if the area is tender, hot, or more itchy than you’d expect.

7. Think about whether any other horses in the same environment have similar skin issues, as that can sometimes point to shared management factors.

Common Causes

The most common cause is prolonged exposure to rain and a wet coat, especially when the skin stays damp for hours at a time. This can allow the skin to become irritated and scabby.

It can also be linked to clipped coats, rugs that trap moisture, or grooming and washing routines that leave the skin damp for too long.

Less commonly, an underlying skin sensitivity, insect irritation, or another skin condition may play a part, particularly if the problem keeps coming back or appears in more than one area.

What To Do

Keep the affected area as dry as you reasonably can and avoid leaving the horse in wet rugs or damp tack. If the coat is soaked, help it dry thoroughly before replacing rugs or turning out again.

Check whether the current turnout, rugging and grooming routine is making the problem worse, and adjust where practical. Gentle grooming can help lift loose crusts, but don’t pick at scabs or scrub the area harshly.

Monitor the skin over the next few days. If it’s improving, that often suggests management changes are helping. If it’s spreading, becoming more painful, or keeping coming back, it’s worth getting it looked at.

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 the coat without being too harsh on already irritated skin.
