What action should be taken if a horse shows moderate to severe fear, anxiety, or stress during a veterinary procedure?

When a horse displays moderate to severe fear, anxiety, or stress during a veterinary procedure, using sedation to safely perform the procedure is the most appropriate action. Sedation can help to minimize the horse's distress, allowing the veterinarian to work effectively and efficiently while ensuring the safety of both the animal and the veterinary staff. This approach acknowledges the horse's emotional state and aims to reduce its stress, creating a more manageable and safer environment for the procedure to take place.

Sedation can help prevent potential injury to the horse or human handlers due to the horse's fear-driven behavior. It is an essential tool in veterinary practice, especially when dealing with more anxious or fearful animals. By providing a calmer state, the veterinarian can proceed with necessary treatment or examination, which may not be possible if the horse is excessively anxious or agitated.

Other methods, such as using ambient lighting or administering oral calming medication, may also contribute to reducing anxiety but may not be effective enough in the moment of high distress. In cases of moderate to severe fear, these alternatives typically do not provide the immediate and effective relief needed to safely conduct procedures.
