FOOT problems and associated lameness in sheep can have important welfare and economic consequences and can be challenging to manage both for clinicians and those involved in sheep production. White line lesions, sometimes causing lameness, are common in many flocks and are often misdiagnosed, which can lead to the administration of inappropriate or ineffective treatments, incur unnecessary costs and result in client dissatisfaction. Such lesions can affect a wide range of age groups, including lambs as young as one to two months of age, rams and pregnant and non-pregnant ewes, indicating that a variety of predisposing factors are likely to be involved. This article describes and illustrates white line lesions in sheep to help farmers and veterinary surgeons make a correct diagnosis.
