Which of the following pieces of equipment is used to calm an anxious horse?

The horse blindfold is used to calm an anxious horse by restricting their vision. Horses can become very stressed when they see or sense things that frighten them, as their natural instinct is to flee from potential threats. By using a horse blindfold, the horse’s field of vision is limited, which can help ease their anxiety and make handling them easier. This tool can be particularly useful in situations where a horse may feel overwhelmed, such as during veterinary examinations or when in a new environment.

In contrast, a hobble is used to restrict a horse's movement, which might not necessarily reduce anxiety and could even add stress in some contexts. A horse cradle is designed to prevent a horse from eating or drinking during certain procedures, while a tail tie is used to secure a horse's tail for grooming or examination, neither of which addresses the issue of anxiety directly.
