In The Elder Scrolls V: Skyrim, players with the Hearthfire expansion can purchase and maintain horses as a means of transportation. Once a horse has been purchased, it can be summoned by whistling. To do this, simply equip the horse whistle in your inventory, select it, and activate it. This will cause your horse to appear nearby.
Horses can be a valuable asset in Skyrim, as they can help you to travel more quickly and easily. They can also be used to carry your belongings, making them ideal for long journeys. If you are planning on traveling extensively in Skyrim, it is well worth investing in a horse.
