Mud Fever - Clinical Signs

Clinical Signs

Mud fever is a chronic but progressive dermatitis. It affects all breeds of horses, but it is most common in heavy draft horses like the Clydesdales. It often starts as a small red ulceration of the skin in the plantar pastern region of the legs. The lesions then grow and develop scaling with the formation of a crust, hair loss, edema, oozing and the release of a malodorous exudate. Skin fissures and papillomatous lesions can develop in chronic cases.
