Mud fever is one of the most common skin conditions in horses—especially during the damp autumn and winter months. This inflammatory skin problem usually appears 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 pastern dermatitis, is an inflammation of the skin on the lower legs of horses. Typical signs include redness, swelling, crusts, and sometimes oozing lesions. If left untreated, mud fever can penetrate deeper into the tissue and cause severe pain.

Causes of Mud Fever

Mud fever usually results from a combination of factors:

• Moisture and dirt — constantly wet or muddy ground softens the skin.

• Bacteria and fungi — invade the weakened skin.

• Mechanical irritation — for example, caused by protective boots or blankets.

• Allergies or skin sensitivities — some horses are more prone to reactions.

Recognizing Symptoms

• Redness or swelling around the fetlock

• Crust formation and hair loss

• Sensitivity when touched

• In severe cases, lameness

Treatment for Mud Fever

• Clean and keep dry — carefully remove mud and dirt, and thoroughly dry the skin.

• Gentle care — avoid harsh products that might further irritate the skin.

• Protect the skin barrier — creams or gels that support skin regeneration can help.

• Consult a vet — if the condition spreads significantly or if there is deep inflammation.
