# Mud Fever Field Guide - **URL:** https://piaffehorse.com/guide-to-mud-fever/ ## Guide to Mud Fever Stay out splashing in the rain and mud long enough and your hands and feet get cold and soggy. If the skin then dries out roughly, it can turn sore and even crack. Horses suffer something very similar on their legs in wet, muddy conditions, and we call it Mud Fever. It is miserable for them, but with the right care you can help your horse feel much better. This guide explains what Mud Fever is, why horses get it, how to spot it and, most of all, how to prevent and treat it so your horse stays happy and healthy whatever the weather. The whole job is keeping the skin strong and protected, in the same way you would guard your own hands against chapping in winter. ### What Exactly is Mud Fever? Mud Fever, also known as Pastern Dermatitis, is a skin condition that usually affects the lower legs, especially around the pastern (the area just above the hoof). A mix of bacteria and sometimes fungi that love wet, muddy conditions causes it. Skin that is constantly damp and soft, and then gets rubbed or scratched by mud or grit, grows weaker. Weak skin works like an open door for tiny germs. Compare it with your own hands, which chap if they are always wet and then rub against something rough. A horse’s lower legs are often covered in hair that traps moisture and mud, and that makes the problem worse. The skin gets irritated and inflamed and can develop scabs, sores and sometimes painful cracks. ### How Does Mud Fever Happen? Mud Fever never appears out of nowhere. Several things usually combine to create the perfect storm for these tiny invaders: - Lots of Mud and Moisture: Moisture is the biggest factor. Horses that stand in wet, muddy fields for long periods get soggy skin, and soft skin protects itself less well. - Damaged Skin: Mud, grit, rough bedding or even sand can rub tiny scratches or breaks into the skin. Those small cuts are little doorways for bacteria. - Lack of Air: Thick hair on the lower legs (called “feathers” in some breeds) can hold moisture against the skin. The skin stays wet too long and cannot dry out properly. - Weakened Immune System: Horses get sick when their immune system is not strong, just as people do. A horse that is not feeling 100% may be more likely to get Mud Fever because his body is not as good at fighting off the germs. - Poor Drying: Legs that are washed after getting muddy but not dried thoroughly stay damp, and that can make the problem worse instead of better. ### Who Can Get Mud Fever? Any horse can get Mud Fever, but some are more prone to it than others: - Horses with White Legs: White skin is often more sensitive to sun and can be more delicate, so problems start more easily. - Horses with “Feathers”: Breeds like Clydesdales, Shires and some Cobs have long, thick hair on the lower legs. It is beautiful, but the feathers trap mud and moisture against the skin and make it harder to keep clean and dry. - Horses with Sensitive Skin: Some horses simply have more sensitive skin that reacts more easily to irritation, as some people do. - Older or Younger Horses: Very young foals and older horses sometimes have slightly weaker immune systems, which makes them a bit more susceptible. - Horses in Constantly Muddy Fields: A horse that lives somewhere permanently wet and muddy is at a much higher risk. ### Signs That a Horse Might Have Mud Fever Check your horse’s legs every day, especially in wet weather, because early detection makes treatment much easier. Look out for these signs: - Scabs: Crusty scabs may show on the skin, often around the back of the pastern or heel. They can be small or cover larger areas. - Soreness and Pain: A horse that flinches or pulls away when you touch the leg may be in pain. The leg can feel warm to the touch as well. - Swelling: The affected leg may look a bit puffy or swollen. - Hair Loss: Hair often comes off with a scab when you try to remove it, and a bald patch of raw skin is left underneath. - Cracked Skin: The skin can crack, especially in the creases of the heel. The cracks can be very painful, like a deep paper cut. - Lameness: In more severe cases the horse may be a little lame (limping) because of the pain in his leg. - Oozing or Pus: A yellowish or greyish discharge, especially under the scabs, signals infection. - Lumpy Skin: The skin can feel bumpy or lumpy underneath the hair. If you see any of these signs, act now. ### Why It’s Important to Act Quickly Mud Fever becomes serious when it goes untreated, so act fast. You may think, “Oh, it’s just a few scabs,” but the risks are real: - Increased Pain: The longer it goes untreated, the more painful it gets. Your horse may not want to move or even let you touch his legs. - Spread of Infection: The infection can spread to larger areas of the leg or go deeper and affect other tissues. - Lameness: Severe cases can cause significant lameness, which makes it hard for your horse to walk comfortably or exercise. - Secondary Infections: Damaged skin becomes a gateway for other, more serious infections that can make your horse very sick. - Longer Recovery Time: A small problem can take weeks or even months to clear up if you neglect it. A little care early on saves your horse a lot of pain and saves you a lot of worry later. ### Preventing Mud Fever: Your Horse’s Shield Against the Muck Prevention beats cure, especially with Mud Fever. Here is how you protect your horse: #### Good Management Practices: - Keep Fields Drained: Improve drainage in muddy areas if you can. You can also build “hardstanding” areas with gravel or rubber mats where horses stand a lot, such as around gates or water troughs. - Rotate Paddocks: Moving horses between fields stops specific areas from getting too churned up and muddy. - Limit Mud Exposure: If the fields are very boggy, bring your horse in for part of the day, especially at the muddiest times. - Clean Bedding: Keep the stable clean and dry at all times, because wet bedding can also contribute to skin problems. #### Keeping Legs Clean and Dry: - Careful Washing: Resist the urge to scrub muddy legs vigorously, as that irritates the skin. Let the mud dry naturally and brush it off gently with a soft brush. If you must wash, use a mild shampoo like [Piaffe’s Revive Shampoo](/product/revive-shampoorevive-shampoo/) or [Piaffe’s Repel Oil Shampoo](/product/repel-oil-shampoo/), both designed to be gentle on the skin. - Thorough Drying: This step is CRUCIAL. After washing, or whenever the legs get wet, dry them completely with a clean, soft towel. A hair dryer on a cool setting works for horses that tolerate it. The skin must be bone dry, especially in the creases. - Clip Feathers: On horses with thick feathers, carefully clipping the hair short on the lower legs helps them dry faster and makes problems easier to spot early. Take great care if you do it yourself, or ask an experienced person to help. #### Protective Barriers: - Barrier Creams: In very muddy conditions, a thick barrier cream or ointment helps protect the skin. These creams form a waterproof layer that stops moisture and germs reaching the skin. Look in the [Specialized Care & Protection](/product-category/specialized-care-protection/) category. - Specialized Boots: Some horses wear special waterproof boots or wraps over the lower legs to keep them dry and clean. Check that they fit well and do not rub. #### Healthy Skin from Within: - Good Nutrition: A balanced diet keeps the immune system strong and the skin healthy from the inside out, so make sure your horse gets all the vitamins and minerals he needs. ### Treating Mud Fever: Simple Steps to Help Your Horse Heal If your horse already has Mud Fever, stay calm and follow these steps. Call your vet whenever it looks severe or fails to improve. - Gentle Cleaning is Key: Start by gently removing any dry mud from the affected leg. - Hard, stuck scabs may need softening. Soak the area gently with warm water (perhaps with a tiny bit of mild antiseptic solution, or a very gentle, soothing shampoo like [Piaffe’s Reluminate Shampoo](/product/reluminate-shampoo/) or [Piaffe’s Reluxe Main & Tail Shampoo](/product/reluxe-maintail-shampoo/)) and let it sit for about 10-15 minutes. - Be very gentle! Never pick or forcefully pull off scabs, because it hurts your horse and damages the skin further. Let them fall off naturally once they are soft enough. - Wash the area with a mild, antibacterial wash. A gentle shampoo made for sensitive horse skin, such as one from [Piaffe’s Coat & Body Care](/product-category/coat-body-care/) range, may be suitable. - Dry, Dry, Dry: After cleaning, pat the area completely dry with a clean, soft towel. This step matters just as much as the cleaning. - Leave no moisture behind, especially in the creases of the skin. - Apply Treatment: Once the leg is completely dry, apply a specialized cream or ointment designed for Mud Fever. A product like [Repair Cream](/product/repair-cream/) can be really helpful, since these creams often contain ingredients that soothe, heal and protect the skin. - Some creams also act as a barrier that keeps new moisture and dirt out. - Once the initial scabs are gone and the skin starts to heal, gentle conditioners like [Piaffe’s Release Spray Conditioner](/product/release-spray-conditioner/) or [Piaffe’s Release Spray Conditioner (another version)](/product/release-spray-conditioner-2/) support general skin health around the affected area. They keep it supple and prevent further cracking. - Keep it Clean and Dry: Keep your horse’s legs as clean and dry as possible during treatment. That may mean a stable with dry bedding, or turnout only in dry areas. - Repeat the cleaning and treatment daily until the scabs are gone, the skin looks healthy and hair starts to grow back. - When to Call the Vet: Call if the Mud Fever is severe, very painful or spreading quickly, or if your horse becomes lame. - Call if the skin is hot, very swollen or has a strong bad smell. - Call if the condition does not improve after a few days of consistent home treatment. - Your vet might prescribe stronger medication, such as special creams or even antibiotics, if the infection is deep. ### The Importance of Routine Checks and Care Daily leg checks are the best defense against Mud Fever, which often sneaks up when we are not paying close attention. Make them part of your routine, especially in muddy seasons. A few minutes feeling your horse’s legs for warmth or swelling, and checking for tiny scabs under the hair, can save a lot of trouble. Brushing your teeth every day prevents cavities, and daily leg care stops Mud Fever from getting a foothold in the same way. Regular grooming, including gentle brushing of the lower legs, keeps the skin healthy and strong. The [Piaffe.horse shop](/shop-2/) stocks many useful products for overall horse grooming and care, including gentle shampoos and creams. ### Products That Can Help You Win the Fight Against Mud Fever A good range of horse care products on hand makes a big difference to both preventing and treating Mud Fever.

Good nutrition and regular, gentle grooming are part of it. - Know Your Horse: Learn what works for your individual horse, as some need more protection or specific products than others. - Consult Professionals: Ask your vet or an experienced equine professional for advice if you are struggling with recurring Mud Fever. ### Conclusion: Happy Legs, Happy Horse!
