Mud Fever in Winter: What Causes It, How to Prevent It, and What Helps

Mud Fever in Winter: What Causes It, How to Prevent It, and What Helps


Suggested URL slug: Meta title: Meta description: Blog excerpt: 

Mud fever is one of those winter problems that can creep up quickly & and once it's there, it can be stubborn.

The most helpful approach is usually prevention and early management: keeping skin healthy, reducing constant wet/muddy exposure, and avoiding routines that accidentally make things worse.

This guide keeps things practical and non-dramatic & and if your horse's legs are very sore, swollen, or you're worried about infection, it's always best to speak to your vet.

What is mud fever? (simple explanation)

Mud fever is a common name for skin irritation and infection on the lower legs, often around the pasterns. You might also hear it called pastern dermatitis.

It typically shows up as:

  • Red, sore skin

  • Scabs/crusts

  • Swelling or heat in the area

  • Sensitivity when you touch the legs

Why mud fever is worse in winter

Winter creates the perfect conditions:

  • Wet skin stays wet for longer

  • Mud and grit rub and irritate

  • Bacteria thrive in damp conditions

  • Horses may be turned out in the same muddy gateways/areas for weeks

Add feathers, thick coats, and less daylight for leg checks and its easy for early signs to be missed.

Prevention routine (step-by-step)

If you want one simple takeaway: keep legs as clean and dry as your routine allows, without over-washing.

Step 1: Daily check (takes 30 seconds)

  • Run your hand down each leg

  • Feel for heat, swelling, tenderness

  • Look for early scabs or pink skin

Catching it early is the biggest win.

Step 2: Keep legs dry (practical drying tips)

If legs are wet or muddy:

  • Let mud dry naturally where possible, then brush off gently

  • Use a clean towel to pat dry (don't rub hard)

  • If you're washing, dry thoroughly afterwards especially in feathers

If you can, avoid leaving legs damp and then turning out again straight away.

Step 3: Field management basics (where possible)

Not everyone can change turnout, but small tweaks help:

  • Avoid standing in the muddies gateways longer than necessary

  • Rotate turnout areas if you have the option

  • Use hardstanding/shelter areas to give legs a break from constant wet

Step 4: Barrier support (without overclaiming)

Some owners use barrier creams/products to help protect skin from wet and mud.

The key is: apply to clean, dry legs and keep an eye on the skin underneath.

Step 5: Don't over-wash

Over-washing is one of the most common mistakes.

  • Frequent washing can strip natural oils

  • Wetting and not drying properly can make the problem worse

  • Scrubbing can damage already irritated skin

If you do wash, keep it gentle and dry thoroughly.

Common mistakes that make mud fever worse

  • Washing legs every day & then leaving them damp

  • Picking scabs aggressively (can cause bleeding and more irritation)

  • Covering wet legs and trapping moisture

  • Ignoring early signs until it's painful

When to call the vet

Contact your vet if:

  • Your horse is lame or very sore

  • The leg is hot, swollen, or the swelling is spreading

  • There's discharge, a strong smell, or signs of infection

  • It's not improving with basic management

  • Your horse has recurring mud fever every winter and you need a plan

FAQs

What causes mud fever in horses?

Usually a mix of wet skin, mud/grit irritation, and bacteria getting into damaged skin.

Should I wash mud off every day?

Not always. If you can let mud dry and brush off, it's often kinder than daily washing especially if drying properly is difficult.

Is it better to clip feathers?

Feathers can trap moisture and mud. Some owners clip for easier drying and checking, but it depends on the horse and your management.

Can mud fever spread?

It can affect multiple legs and can be passed via shared brushes/towels. Good hygiene helps.

How do I dry my horse's legs properly?

Pat dry with a clean towel and make sure feathers aren't staying damp. Give time for legs to fully dry before applying any products.

Does turnout make mud fever worse?

Constant wet/muddy turnout can increase risk, especially in gateways and high-traffic areas.

Can mud fever come back every winter?

Yes & some horses are more prone. A consistent prevention routine and early checks help reduce flare-ups.

When should I call the vet?

If there's lameness, swelling, heat, discharge, or it's not improving & get veterinary advice.

Make winter leg care simpler
