Another Minecraft post.
Taming wolves is awesome. With a bone you get from skeletons archers you can equip it and RIGHT click on a wolf. This will make hearts appear over its head and tame the dog. The dog will follow you around and attack things that hit you.
If you don't want to the dog to follow you anymore, right click on the dog and he will sit. I have taken some screens of this and you can see them below. Great way to guard the outside of a house or entrance to something.
