Lameness in horses refers to a condition where a horse shows an abnormal gait or difficulty in movement. This can be caused by various factors, including injuries, arthritis, or hoof problems. Identifying lameness is crucial for maintaining a horse's health and performance, as it can indicate underlying issues that need attention. Veterinarians often assess lameness through physical examinations and diagnostic tools like X-rays or ultrasound. Treatment options may include rest, medication, or corrective shoeing. Early detection and intervention are essential to prevent further complications and ensure the horse's well-being.
