What should I check if my horse's legs are hot and puffy under the mud?

Read time: 3 minutes

Overview

If your horse's legs are hot and puffy under the mud, start by checking the skin, the amount of swelling, and whether the horse seems sore when you touch the area. Mud, soft tissue irritation, filled legs, and mud fever-type skin changes can all make legs feel warm and look puffy, so it's worth looking closely rather than assuming it's just dirt.

Things To Check

1. Check whether the heat and puffiness are on one leg or all four legs, and whether it looks worse after turnout or standing in wet conditions.

2. Look closely at the skin under and around the mud for redness, scabs, cracked skin, discharge, or any sore-looking areas.

3. Feel whether the horse reacts when you gently run your hand down the leg or press around the swollen area, as soreness can point to more than simple mud.

4. Check the lower legs, pasterns and heels carefully, because mud fever often starts in these wetter, more exposed areas.

5. Notice whether the puffiness goes down after the horse has been walked or moved, or whether it stays the same and feels tight.

6. Look for cuts, abrasions, mud clumps stuck to the skin, or anything that may have rubbed under the coat or feathering.

7. Check the general condition of the horse, including whether they seem off colour, uncomfortable, or less willing to move normally.

Common Causes

The most common reason is simple mud-related skin irritation, especially in wet fields where the lower legs stay damp for long periods. This can make the skin feel warm and look puffy.

Filled legs can also happen after standing still for a while, particularly in muddy or wet conditions, and may ease once the horse moves about.

Mud fever is another common possibility, especially if there are scabs, redness or broken skin on the lower legs.

Less commonly, the heat and swelling could be linked to a knock, an insect bite, or another skin or soft tissue problem that needs a closer look.

What To Do

Start by gently removing excess mud so you can see the skin properly. Use care when cleaning, and avoid scrubbing hard if the skin is already sore or broken.

Dry the legs well after washing or cleaning, and keep an eye on whether the puffiness changes over the next 24 hours. A short walk may help if the issue seems like simple filled legs, but don't force exercise if the horse seems uncomfortable.

Try to reduce further wetting where you can, and keep the horse's environment as clean and dry as possible. Regular checks are useful because early skin changes can be easy to miss under mud and feathering.

When To Contact A Vet

Contact your vet if the swelling is getting worse, the legs are very painful, the horse is lame, the skin is broken and sore, or the swelling doesn't improve after you clean and dry the area. It's also sensible to get advice if your horse seems unwell or the problem keeps coming back.
