No, it is unethical and illegal to use electric shocks to make horses run faster. This practice will not only cause great pain and injury to horses, but may also cause serious health problems and even lead to the death of horses. In addition, this behavior violates the basic principles of animal welfare and may be severely sanctioned by law. Horses are sensitive animals, and their health and well-being should be respected and protected. In horse racing or other equestrian activities, the performance of horses should be improved through scientific training, reasonable nutrition and good care, rather than by mistreating or harming them to achieve their goals. If you have questions about how to improve the performance of your horses, it is recommended to consult a professional equestrian coach or veterinarian, who can provide legal, ethical and effective ways to help your horses perform at their best. Please always remember that it is the responsibility of each of us to be kind to animals.
