Wolf

Wolves are new mobs which were introduced in Beta 1.4. Notch had confirmed the addition of these animals upon having breakfast with an idol of his, likely Peter Molyneux. On March 18th, 2011, a video was posted showing a preview of the wolves, which were being made by Jeb. Wolves spawn in forest and taiga biomes.

Taming
To tame a wolf, you have to give it bones until a puff of heart particles appears and it gains a red collar, indicating that the wolf has been tamed. The number of bones required is random. You can have more than one tame wolf at a time. At the moment, there is no limit on the number of wolves a player may tame until Mojang decides to create a limit.

Once given enough bones, they will become friendly. They will now protect you, follow you around, and will attack mobs that you have attacked in melee. Tamed wolves will not attack mobs that you hit with arrows, nor will they attack creepers. Sitting wolves will only attack if their owner is attacked. A wolf's tail will rise and lower depending on its health, and it can be restored with cooked or raw pork (which can also be used for luring them). Wolves are able to eat other foods, but only raw/cooked porkchops will heal them. They are unable to climb ladders, but will teleport to you if you create a large distance between yourself and them as long as they are not sitting or trapped in a minecart. On a rare occurrence tamed wolves can duplicate. Tame wolves will attack you if you get one of your own arrows to hit you. They will attack like this even from the sitting position.

To help yourself find wolves, make a small house inside a forest or taiga biome, then sleep inside it for a couple of nights. These Mobs only spawn when you are 24 blocks away from them, so sleeping in the middle of/ near where wolves spawn will help you find them much quicker. There must be a few torches near where they will spawn. Another excellent tactic to find wolves is to find a snowy biome and a grassy biome, preferably 60 blocks apart. Then, put torches in each of the biomes. Start by waiting at the grassy biome for a few moments, then walk towards your snowy biome. Kill/tame any mobs and return to the grassy biome. Return to the snowy biome and do the same (kill/tame any mobs). This is a good tactic because you can have spawning points in both possible biomes of wolves. (Tamed wolves spawn more frequently as of 1.5, therefore such tactics are not needed in wolves' preferred biomes)

Tamed wolves, like wild wolves, will tilt their head when shown something they can eat such as porkchops. They do not take any more bones once tamed.

Wild/Untamed
Wolves spawn in neutral (untamed) packs of 1-8, Wild wolves will randomly attack nearby sheep and pigs, but will not attack the player unless provoked. A good indicator that there are wild wolves nearby would be wool blocks floating on the ground and you didn't shear any sheep at that time. If you switch to a Bone, wild wolves will tilt their head to the side, indicating interest in the delicacy the player is holding up. Wolves can swim, and will shake water droplets off of their bodies when exiting water. They will not go underwater, however. They also seem to have a simple pack behavior as they always "hunt" sheep and pigs together.

Hostile
Wolves will become hostile towards the player if attacked. Hostile wolves change in appearance: their eyes become red and the contrast level of their fur texture increases (perhaps meant to indicate hair bristling). Hostile wolves will attack the player as a pack. On multiplayer if one player attacks a wolf, that wolf will be hostile to all players. Hostile wolves will growl when near the player. Although you can usually outrun hostile wolves, and a single wolf only has a 0.5 attack strength, it is not recommended that you turn a wolf hostile because they are rather rare and useful once tamed. However, in large groups they can take quite a toll on your health if the whole pack becomes hostile. Once a wild wolf becomes hostile, it can't be tamed. A fishing rod can make a wolf hostile if you try to pull the wolf

Tame
When tamed, a wolf's eyes will change to two white pixels and one black pixel, making it look less aggressive. Tame wolves will join into melee combat against the player's current target, with a few exceptions. Wolves will only target one mob at a time and will not switch targets until it is killed. They will never attack creepers. They will also not attack if they are sitting, though they will stand and defend the player if he is attacked. They also stand up if they are attacked by the player. This can be utilized to "call" sitting wolves from a distance by throwing a snowball at them or catching them with a fishing rod. Wolves also constantly bark.

Tame wolves turn their head to the side and beg if the player is holding a cooked or raw porkchop. When told to sit, tamed wolves will perform an idle animation by turning around and looking at their surroundings.

Wolves do spawn in "Peaceful" Mode and will still attack if provoked. When changing the difficulty to "Peaceful," tamed wolves are not removed from the game.

If you manage to hit yourself with an arrow, your tamed wolves will attack you. Because they will be friendly towards you after respawning, it is usually better to let them kill you than to kill them. You can also save and quit, then re-enter.

Health
A wolf's health status may be determined by checking its tail; the angle between his hind legs and tail indicates its health (100° for 100%, 50° for 50% health). Tamed wolves will whimper if they are low on health. If a wild wolf appears to have low health because of a lowered tail it's health will be restored to 100% after it has been tamed (even if no porkchops were fed to it). Feeding a wolf cooked or raw porkchops will increase its health by $1 1/2$ hearts. If you make a wolf sit down then feed it cooked or raw porkchops the wolf will stand up when it reaches 100% health. Wolves cannot eat anything other than raw or cooked porkchops. If you try to feed your wolf something other than raw or cooked porkchops, it will not heal the wolf, either making it stand or sit depending on the position it was previously in.

Porkchop
If you hold up a porkchop to a standing tamed wolf, it will come running at you 13% faster than normal, and will most likely avoid running away from the player.

If you look at a wolf's tail, it will either be down or up. If a wolf's tail is down, it means it is low on health, and if it's tail is high, it probably won't need food. If you have a wolf standing, and you right-click on the wolf with a Porkchop in your hand, you will "Feed" the wolf the Porkchop. The wolf will regain after being fed the pork, which means that your wolf will last longer in a fight against mobs.

Movement
Tame wolves will follow you but also wander around. They will take any available path to the player, not just walk directly towards like hostile mobs do. They can walk through fully open double doors with ease, but can only walk through a singular door if they are jumping and trying to go through it or being pushed by another mob. Wolves are able to walk through 1x1 holes and can turn around in them. Wolves will attempt to walk through obstacles in order to attack, but will not path around them. Tamed wolves will follow you up ladders only if they are pushed on them.

Wolves often jump around when the player is not moving, and often receive fall damage when near cliffs or even gradual descents. When following the player down a descent, they will often find a safe path to the player rather than a straight path to the player, avoiding fall damage. Wolves will not avoid walking into lava, cacti, or fire, and so may die even if they're following a player taking a safe route.

Wolves will teleport to you if they get too far behind (which happens often). Teleporting resets the wolf's list of targets, so if a wolf is attacking a mob and teleports it will stop attacking. The distance between you and a wolf before it teleports is roughly 32 blocks. It is possible for tame wolves to teleport to an inaccessible location (such as under ice) and may die as a result. A Wolf in a minecart will have trouble teleporting to you, and a wolf will not teleport to you if you are swimming in water that is deeper than 1 block or if you are in a minecart. They will also not teleport to you if you are standing on ice, but they will respawn next to you when you get close enough to land. If a wolf is standing on the edge of its 32-block teleport limit and the player melee attacks a non-creeper mob, then moves away from the wolf very quickly, the wolf will teleport to the player but not attack the mob.

When you right-click on a wolf they will sit and stay in that spot, and will not teleport to the player. A wolf will stand up if it is in water or when it is hurt (including by being on fire, so it is difficult to keep a wolf on fire from wandering back into the fire).

Wolves cannot travel to the Nether; if the player does, the wolves will remain in the first world until the player returns.

Drops
Beta
 * Nothing

History

 * Wolves were released in Beta 1.4, on March 31st, 2011.

Bugs

 * If you save while your wolves are sitting, they may never stand up again. To fix this, get something to damage you (spider, skeleton, zombie, etc.) This can also be fixed by dumping water on them.
 * Wolves don't stand up if you are playing in offline mode if the game was saved while in online mode, as well as the reverse instance of saving while offline and playing online. However, doing the above may fix the problem.
 * Although wolves are meant to spawn in Taiga and Forest biomes only, they can (rarely) be found elsewhere.
 * If Minecraft crashes, the number of tamed wolves you have may increase. However, some might also disappear.
 * There is a glitch that when a tamed wolf is inside a minecart (standing), if you go too far away from your wolf, the wolf will teleport to you and it will immediately fly back into the minecart, this will happen repeatedly. This can be fixed by destroying the minecart.
 * If a wolf is swimming, Minecraft will sometimes play the "shaking" sound.
 * If you tame a wolf while it's in the middle of jumping, the wolf will go into a "sitting" pose, but continue to bounce up and down indefinitely. This can be fixed by making the wolf sit.
 * Wolves can push you out of your bed, but you will still sleep.
 * In SMP, a player who logs in will see all sitting wolves as standing until they are removed and put back into position.
 * Tamed wolves can teleport inside transparent blocks such as slabs. This can mean they can get stuck, or not follow you.
 * It is possible to push a wolf into a block and therefore suffocate it, done by having two wolves sit, and then pushing one wolf by the other into a solid block.
 * A rare glitch has been known to occur when you save while a tamed wolf is sitting. When you come back to the game and make it stand up, then just right after you've clicked (you need to be very quick), hold up a porkchop, and the wolf will run towards you in sitting position.
 * A tame wolf will attack you if you shoot yourself with an arrow.
 * If a tamed wolf attacks a mob and you right-click on the wolf, it jumps towards the mob in sitting position
 * Sitting tamed wolves, that were tamed before 1.5_01, that are pushed into water, or that water runs over, will start to jump in place, keeping the sitting stance, and are no longer able to be told to stand, thus continuing to do this until hit, which will cause them to attack you until death on either side. This can be fixed by killing the wolves off and taming new ones.
 * Dumping water on wolves that were tamed before 1.5_01 and left sitting, will cause them to stand up, shake off the water and go back into the sitting position.
 * Trying to get a wolf to stand up if it was tame before 1.5_01, will cause it to attack you if you dealt it damage, just as a hostile wolf, however it will still have the friendly appearance. it will begin to bounce and attack you. even if you walk away, then walk back you will be dealt damage, even if the wolf is not looking at you.

Trivia

 * When wolves attack a big (2 ) slime, they simply push the slime around.
 * Wolves cannot go into the Nether unless hacked in. They behave no differently than if they were in the normal world.
 * Wolves are the first official tameable mob in Minecraft.
 * Jeb has said that wolves may have color variations, but he "would have to run that through notch".
 * Wolves do not trample crops. They will also not make step sounds, or make quieter ones than default.
 * If a hostile mob (besides a creeper) attacks a player, the wolf will react and attack the mob to defend the player, even if the wolf was told to sit. This means that they will attack the player if the player injures himself, i.e. through shooting oneself with arrows. This can be extremely useful if the player is trying to sleep and is attacked in their sleep, as it's more than likely the wolves will be beside the player at the time.
 * If you attack another player on SMP, even if PvP is off, a tamed wolf will attack the opposing player.
 * If a wolf is in a downward water current, they will not float, and if not removed will drown.
 * Wolves and Slimes are the only mobs that can be hostile to the player on peaceful mode.
 * If you die, the wolf will not teleport to you, but it can be recovered by returning to the spot of death.
 * Judging by the color of its coat and the biome in which it spawns, the wolf in Minecraft seems to be based on the real world gray wolf.
 * Hostile wolves respond similarly to zombie pigmen, as attacking one will make the whole pack attack you.
 * Wolves have a brown markings on their coat. When they are Hostile, the markings become darker. When Tamed, the markings become lighter.
 * If you attack a mob, then order a wolf that is pathing to attack the mob to sit, the wolf will attack the mob by bouncing toward it while sitting.
 * Wolves can teleport into transparent blocks. Therefore, it is not recommended bringing a wolf underground, or near lava/fire.
 * Wolves do not survive drops even with a water break.
 * If you tame multiple wolves, one wolf will always follow you on foot. However, if you move a large distance relatively fast (ie: walking in a straight line across a plain) one or more of the other wolves will idly walk in circles upon becoming a certain distance away, and will teleport if the player moves any farther away.
 * Prior to 1.5, wolves continuously made whimpering noises even when they were at full health because Jeb mistakenly used client-side health instead of synced health.
