Horse Armor

Horse armor is a special type of armor that can be given to a horse to wear. Horse armor has infinite durability and can be found in dungeons as well as Nether fortress chests, Village Blacksmith chests, Jungle Temple and Desert Temple chests, and in abandoned mineshaft minecart chests. Horse armor protects the horse from attacks.

When on a horse, the player can press the inventory button (default E) to access the horse's inventory. This allows the armor to be applied, removed, or replaced at the player's leisure. When the player is off the horse, the player may right click the horse with armor to equip the armor.

Horse armor cannot be enchanted in survival mode, but you can use an anvil in creative mode. Enchanted horse armor will not have any effects on the horse.
