Grass – horses love grass. It’s their natural food and great for their digestive system (although beware of your horse eating too much lush grass in spring as this can cause laminitis).
Horses like to eat sweet treats, whether it be candy, fruits, or sweet grains. Some of their favorites include watermelon, apples, strawberries, bananas, and peppermints. But because of their complex digestive system, horses have to eat a certain amount of forage, and most like alfalfa hay the best.
