Using electric shock as a training method to make horses run faster not only has huge ethical and animal welfare issues, but it may also be counterproductive. The following points need to be noted: 1. Harm to animal welfare: Electric shock can cause pain, fear and stress to animals, which may cause psychological and physical harm. Many countries and regions have introduced relevant regulations to restrict or prohibit the use of negative stimulation methods that cause pain to animals for training. 2. Unstable training results: Negative stimulation (such as electric shock) often causes fear and distrust in animals, which may interfere with the good relationship between horses and trainers in the long run, thus affecting the effectiveness of training. In contrast, positive reinforcement and reward methods can better cultivate the enthusiasm of horses, allowing them to learn and exercise in a happy mood and improve their performance. 3. Regulatory restrictions: In many places, using electric shock or other forms of painful stimulation to train animals may violate animal protection laws and be considered abuse. 4. Alternative methods: Professional equestrian training usually adopts a step-by-step training method, using rewards, positive motivation, patience and consistency to shape the behavior of animals. A good trainer will develop a training plan based on the horse's physical and psychological state, rather than relying on short-term means to stimulate a "sprint" response. In summary, electric shock is not only detrimental to the physical and mental health of horses, but also easily raises ethical and legal issues. Therefore, if the goal is to improve the performance of horses, it is recommended to use scientific, humane and proven training methods and conduct them under the guidance of professional trainers.
