What should I check on my horse’s rug if rain scald keeps returning?

Read time: 3 minutes

Overview

If rain scald keeps returning, the rug is one of the first things to check. Look for damp patches, rubbing, poor fit, damaged waterproofing and areas where mud or sweat may be sitting against the coat. Rain scald can have more than one trigger, so the rug may be part of the problem even if it isn't the only cause.

Things To Check

1. Check whether the rug is leaking, especially along the back, seams, shoulders and around the neck area.

2. Look for wet or sweaty patches under the rug after turnout, as trapped moisture can keep the skin damp.

3. Check for rubbing at the shoulders, withers, chest and along the mane or back, where the rug may be moving.

4. Make sure the rug fits properly and isn't too tight, too loose or slipping to one side.

5. Inspect the inside of the rug for dirt, mud, old hair, sweat or stiff areas that could irritate the skin.

6. Check the weathering of the rug fabric, including worn patches, torn lining or damaged fastenings that may affect coverage.

7. Look at where the rain scald appears on your horse, because patches that match pressure points often point to a rug issue.

Common Causes

The most common reason rain scald keeps coming back is that the coat is staying damp under the rug, either from rain getting in or from sweat that can't dry properly.

Poor fit or rubbing can also make the skin more vulnerable, especially if the rug shifts during turnout.

Dirty rugs, damaged waterproofing or worn seams may let moisture and irritation build up over time.

Sometimes the rug is only part of the picture, and grooming, mud, coat condition or the horse's sensitivity to wet weather may also play a role.

What To Do

Take the rug off when you can and check the skin carefully before putting anything back on.

Wash and dry the rug according to the care instructions if it is dirty, sweaty or holding moisture.

If the rug is rubbing, try to identify the pressure point and make sure the fit is correct before using it again.

Use a clean, dry rug so the skin isn't repeatedly sitting against damp fabric.

Keep an eye on how quickly the problem returns, and note whether it follows wet weather, turnout, exercise or a particular rug.

If the skin is broken or the area looks sore, avoid anything that might add more friction until you've checked it properly.

When To Contact A Vet

Speak to your vet if the skin is repeatedly getting worse, there is swelling, discharge, significant soreness, or the horse seems unwell. Ongoing cases can sometimes need a closer look to rule out infection, allergy or another skin issue.
