Lameness refers to a condition where an animal, often a horse or dog, has difficulty walking or moving normally due to pain or injury. This can result from various issues, including joint problems, fractures, or soft tissue injuries. Lameness can be temporary or chronic, depending on the underlying cause. Identifying lameness typically involves observing the animal's gait and behavior. A veterinarian may perform a physical examination and diagnostic tests, such as X-rays, to determine the cause. Treatment options vary and may include rest, medication, or surgery, depending on the severity of the condition.
