Mud fever is one of the most common skin conditions in horses—especially during the damp fall and winter months. This inflammatory skin condition usually occurs around the fetlock area and can be painful and uncomfortable for your horse. But what exactly is mud fever, how does it develop, and what can you do to help your horse quickly?

What is mud fever?

Mud fever, also known as fetlock dermatitis, is an inflammation of the skin on a horse’s lower legs. Typical signs include redness, swelling, scabs, and sometimes weeping sores. If left untreated, mud fever can spread deeper into the tissue and cause severe pain.

Causes of mud fever

Mange is usually caused by a combination of several factors:

• Moisture and dirt – floors that are constantly wet or muddy can cause the skin to become soft.

• Bacteria and fungi —penetrate weakened skin.

• Mechanical friction —e.g., from leg wraps or blankets.

• Allergies or skin sensitivities – some horses are more sensitive.

Recognizing symptoms

• Redness or swelling around the pastern

• Scaling and hair loss

• Sensitivity to touch

• In severe cases, lameness

Treatment of mud fever

1. Keep clean and dry – gently remove mud and dirt, and dry the skin thoroughly.
2. Gentle care – do not use harsh products to avoid further irritating the skin.
3. Protecting the skin barrier – creams or gels that help the skin regenerate can be helpful.
4. Consult a veterinarian – if the infection has spread extensively or if there is deep inflammation.

Did you know? The skin barrier plays a crucial role in defending against pathogens. If it is damaged, bacteria and fungi have an easy time of it. Quick and targeted support can significantly shorten the healing process.
