What causes rain scald to get worse in cold, wet weather? | arlo.® Atlas

Read time: 3 minutes

Overview

Rain scald can seem to get worse in cold, wet weather because damp skin stays soft for longer, the coat dries slowly and the skin’s natural barrier may be more easily disturbed. In simple terms, the conditions make it easier for the scabs and sore patches to spread or stay active. It can also look more obvious when the coat is wet, but there may be several reasons for that change.

Things To Check

1. Check whether the patches are appearing after turnout, following prolonged rain, or where water sits on the coat.

2. Look closely for scabs, lifted hair, redness, tenderness, discharge or areas that feel warmer than the surrounding skin.

3. Check the most exposed areas first, especially the back, rump, neck and anywhere the coat stays damp for longest.

4. Consider whether rugs, turnout clothing or tack are rubbing or trapping moisture against the skin.

5. Think about grooming and washing routines, especially whether the horse has been left damp after washing or heavy rain.

6. Check whether mud, wet bedding or a very damp stable environment could be keeping the skin moist for long periods.

7. Notice whether the problem seems to recur in the same places each wet season, which can suggest a management pattern rather than a one-off issue.

Common Causes

The most common reason rain scald seems worse in cold, wet weather is prolonged dampness. Rain, mud and slow drying can weaken the skin surface and make scabs more noticeable.

Rugs that hold moisture, fit poorly or rub can add to the problem by keeping certain areas wet and irritated.

Grooming or washing practices can sometimes make things seem worse too, especially if the coat is not dried properly afterwards.

Less commonly, an underlying skin sensitivity, bacterial irritation or another skin problem may be contributing, especially if the area is spreading, very sore or not improving with sensible care.

What To Do

Keep the horse as dry as you reasonably can and avoid leaving wet rugs on for long periods. If the coat is soaked, allow it to dry fully when you can, and make sure bedding and shelter are as dry and clean as possible.

Handle affected skin gently. Avoid picking scabs hard or scrubbing the area, as that can make the skin more uncomfortable.

Watch for patterns. If the issue flares after turnout, after rain or after certain rugs are used, that information is useful for changing the routine.

Small changes to turnout, rugging and drying routines can often help support the skin while it settles, especially during a wet spell.
