Pay careful attention to the physical and mental needs of horses. As an equestrian, you are responsible for the well-being of the horses around you. Make a daily, weekly, and monthly calendar in which you note major health appointments. Use this calendar to also keep track of how much, and what items, you feed your horse every day. And, keep an eye out for your horse’s mental status. If your horse begins to act out violently or is really lethargic, it may need some extra attention or even a change of stall.
