George Washington had a unique practice of having his horses' teeth filed or smoothed to prevent discomfort or injuries caused by sharp edges. He believed that this practice improved the horses' health and performance. This attention to his horses' dental care was one of many examples of Washington's commitment to caring for his animals.
