Wolf

Wolves are a mob from vanilla Minecraft that have been in Middle-Earth since Public Beta 11.

Spawning
Wolves will rarely spawn in many forested biomes of western Middle-Earth, including (but not limited to), the Trollshaws, Dunland, Lone-Lands Hills. They spawn there day and night, regardless of alignment, but only on grass blocks.

Behaviour
Wolves will not attack the player or other NPC's unless provoked. If provoked, Wolves will attack the offending player or NPC, dealing two hearts of damage per hit. They are not aligned with any particular faction. They will sometimes attack and kill nearby sheep.

Taming and feeding
A wolf can be tamed using either vanilla bones or any of the bones added by the mod, as of Public Beta 27. They will eat most types of meat to heal. Tamed wolves will attack anything that the player attacks, or that attacks the player. They will also teleport with the player upon fast-travelling. They will, however, not respond to the Sword of Command or the Horn of Command, and will not heal on their own.

Considerations
Because most NPC's in Middle-Earth are armoured, have high hitpoints, or both, Wolves tend to be significantly less effective at protecting the player in Middle-Earth than they are in vanilla Minecraft; almost every NPC can kill a wolf in one-on-one combat. Also, hired archer units and wolves tend to not be a good mix (at least in older versions), because if the archer accidentally shoots the wolf, he will attack the archer, sometimes resulting in the death of that unit (or the wolf). Despite this, Wolves can be good companions early on in the game, or for pacifists.
