Mud fever in horses: What is it and how is it treated?

Mud fever is one of the most common skin problems in horses, especially during the damp fall and winter months. This skin condition usually affects the fetlock area but can also spread upward. It’s not only unsightly but can also be very painful for your horse. In this article, you’ll learn exactly what mud fever is, how it develops, and which treatments are truly effective.

What is mud fever?

Mud fever, also known as fetlock dermatitis, is an inflammation of the skin in the fetlock area. It often starts with small red patches and scabs, but can spread quickly and, in severe cases, lead to weeping, deep sores. If left untreated, mud fever can severely limit your horse’s mobility.

Causes of mud fever in horses

There are many causes of mud fever, and it is usually the result of a combination of factors:

• Moisture and mud: Constantly damp conditions soften the skin and make it more susceptible to germs.
• Bacteria, fungi, or parasites: they penetrate through damaged skin and cause inflammation.
• Mechanical friction: e.g., from gaiters, straw, or hay.
• Allergies or skin sensitivities: some horses react more strongly to environmental stimuli.

Mud fever in horses: Recognizing the symptoms

Common signs of mud fever include:

• Redness and swelling around the pastern
• Scabs, hair loss, and cracked skin
• Weeping or oozing areas
• Sensitivity or lameness

The sooner you recognize the symptoms, the easier it is to treat mud fever.

Treating Mud Fever: Step by Step

1. Cleaning: Gently clean the affected area without further irritating the skin.
2. Drying: Keep the legs as dry as possible; avoid wet bedding and muddy paddocks.
3. Care: Use gentle, skin-friendly products that support the skin barrier.
4. Protection: Protect the skin from further moisture and friction.
5. Veterinary care: Always consult a veterinarian if your horse has severe or worsening mud fever.

Did you know? Your horse’s skin barrier is its most important defense against bacteria and fungi. If it becomes weakened, pathogens can easily penetrate the skin and cause inflammation. Targeted care can not only speed up healing but also reduce the risk of recurrence.
