If you are reading this, you need a faithful steed at your side.
In update 1.6., after being nagged at for quite a while, Jeb finally added horses to Minecraft. Horses are the newest mob addition to the game, and can be found in the Savannah and Plains biomes. There are 35 possible breeds of horses, and the properties each horse possesses is different, such as full jump hight, health, and speed.
Horses can be bred by feeding them apples, golden apples, wheat, and hay bales. The growth of the foal can be accelerated by feeding it the items already mentioned. To tame them, mount them by right clicking on them. You will be probably be thrown off a couple of times. When you see hearts, press your inventory button to open the horse inventory.
To control the horse, you will need a saddle. Sadly, they cannot be crafted and need to be found in Nether Fortresses, and in dungeons. They can be tied with a lead to a post, or you can lead your horse around with it. Horse armour can only be found in dungeons and Nether Fortresses, just like the saddle. There are three armour variants. In order from weakest to strongest, they are: Gold, Iron, and Diamond.
Horses can be used to jump fences, barriers 2 blocks high and over. When the player parries while riding a horse, he does not slow down. The same goes for shooting with the bow. The horse is not hindered by either of these factors.
I hope this has been some help for everyone.
