Wolf

Wolves are neutral mobs that can be allied with the player. In other words can be tamed

Spawning
Wolves only spawn naturally in forests, taiga, mega taiga and cold taiga, as well as the "hills" and "mutated" variants of taiga, mega taiga and cold taiga. In the Pocket Edition they only spawn naturally in taiga biomes and their variants.

Naturally-spawned wolves are untamed, and will become hostile if attacked by the player.

Drops
Wolves drop 3 experience when killed by a player or tamed wolf.

Behavior and appearance


Wolves can exhibit three different states depending on how the user interacts with them:


 * Wild wolves have gray fur, a drooping tail, and their eyes consist of two white pixels and two black pupils. They are neutral towards the player and spawn in packs of 4. They will attack rabbits, skeletons, wither skeletons, strays, and sheep without provocation. However they will run away from llamas.


 * Hostile wolves can be distinguished by their constant growling and appearance. Their tail becomes straight, their eyes become red and the contrast level of the fur increases, revealing dark patches of bristling hair and a mouth line raised in a slight snarl.


 * Tamed wolves can be distinguished from wild or hostile wolves from their eyes since they change to look less aggressive. They have a red collar around their neck, which can be dyed using any color of dye on the wolf. Pressing  on the wolf makes it sit and remain in place while the player is free to move around. Tamed wolves will attack players or mobs that injure their owner, unless the target has the same owner or is on the same team. Standing wolves will attack players or mobs that are attacked by their owner, unless the target has the same owner or is on the same team. They will also not attack creepers, ghasts, or tamed horses regardless of owner. Standing tamed wolves will attack skeletons, wither skeletons and strays without provocation, but not sheep or rabbits.

A wolf will become hostile towards a player or other mob that attacks it, unless the attacker is the wolf's owner or is otherwise on the same team, and will also cause nearby wild wolves and standing tamed wolves (in a 33×33×21 cuboid centered on the attacked wolf) to become hostile towards the attacker.

Skeletons, wither skeletons, strays and passive rabbits will actively avoid wolves, killer rabbits will attack them, and sheep will ignore them beyond their normal running after being damaged.

Wolves are 0.85 blocks tall, and baby wolves are 0.425 blocks tall.

Movement
Standing tamed wolves will wander randomly when near their owner, but will follow if more than 10 blocks away and will teleport to a nearby free block (if any) if more than 12 blocks away. Besides making travel easier, teleporting can be used to rescue them from lava, water, or pits.
 * Wolves can be told to "sit" by pressing on them, and made to stand again with another press of.
 * When originally tamed, they will start off sitting.
 * While sitting, they will not follow the player. However, if their owner fights a mob near them, they are still likely to join the fight. When the fight is over, they will go back to sitting (if in water, they won't sit until they are on dry land). They will sit at their new location instead of returning to wherever they were previously.
 * Wolves will stand up and follow the player if pushed into water or injured while sitting.
 * Wolves can find paths to their targets if attacking, even in craters. They will also navigate along the edges of cliffs, but will occasionally take drops long enough to damage them.
 * Wolves attack their targets by leaping at them in exactly the same manner as spiders, but cause no damage while in midair. Tamed wolves will attack an animal the player starts to attack.
 * Wolves can navigate and turn around in 1 × 1 horizontal tunnels.

Teleportation
Tamed wolves will teleport to their owner if they are more than 12 blocks away, with a few caveats.
 * Teleporting resets the focus of a tamed wolf, so if a wolf is attacking a mob and teleports beside a player, it will resume following the player.
 * It is possible for tamed wolves to teleport to an inaccessible location and be injured or die of suffocation as a result.

A wolf will not teleport:
 * If the wolf has been ordered to sit.
 * Exception: The wolf is likely to teleport if it is injured while sitting (it will no longer be sitting after it teleports). An example is if a wolf that is sitting is hit by another player, it will teleport to their owner.
 * Exception: If the wolf is in a loaded chunk, and the player gets damaged by a mob, there's a chance the wolf will get up from sitting, causing them to teleport if the player is far away, then attacking the player's attacker and sitting down afterwards.
 * If the wolf is in a minecart.
 * If the wolf has been attached to a fence post with a lead.
 * If the wolf is in an unloaded chunk.
 * If none of the blocks on the edge of a 5×5×1 region centered on the player are transparent blocks with a solid block below and another transparent block above.
 * If the player is in another dimension; a wolf will remain in its current dimension until the player returns. However, wolves can be transported to another dimension by pushing them into the portal first.

Taming, health and feeding


A wolf can be tamed by feeding it bones. Once tamed, a wolf will not accept any more bones. Note that the number of bones required is random – each bone has a 1/3 chance of taming the wolf. If the wolf is tamed, it will get a red collar and (if not swimming) the wolf will sit down. Currently, there is no limit to the number of wolves the player can tame.

A wolf's tail will rise and lower depending on its health. The exact health of an individual wolf can be determined by measuring the angle between its hind legs and tail. The angle indicates the percentage of health that the wolf has. Wild wolves have a maximum health of, so their tails will always remain significantly lower than those of tamed wolves. Tamed wolves can be healed by feeding them any sort of meat other than fish; this will restore as much of the wolf's health as the same food would restore hunger points when eaten by the player.

Puppies have only health when born, but their maximum health is the same as an adult's -, and they can be raised to full health by feeding them or using splash potions of healing. Note that wolves do not get food poisoning, so they can freely eat rotten flesh or raw chicken. Feeding a tamed wolf which is already at full health will usually start the "love mode" animation.

A tamed wolf's collar color can be changed by a dye on the wolf.

Breeding


Wolves can be bred, if tamed and at full health, through the use of any type of meat.

The growth of baby wolves can be slowly accelerated using any type of meat. Each use takes 10% off the remaining time to grow up.

The behavior of puppies is the same as tamed wolves. The appearance of the pups differs, however, as they have large heads, similar to the offspring of pigs, cows, sheep and so on.

Breeding two wolves that recognize someone else as an owner will cause the puppy to also be owned by the owner of the original two wolves. If two tamed wolves with different owners are bred, the puppy will usually be owned by the owner of the wolf bred last.

Data values
Wolves have entity data associated with them that contain various properties of the mob. Their entity ID is.

Trivia

 * If a tamed wolf is named with a name tag, its name is shown in the chat when killed.
 * Wolves do not trample crops (but they can destroy them by jumping on them.).
 * Wolves can teleport into transparent blocks.
 * If you attack a wolf and then give the aggressive wolf food that it can eat (like rotten flesh), hearts will appear as animals do when entering breeding mode, however the wolf will not breed and will continue attacking the player.
 * Aggressive wolves can see you even if you are invisible.
 * In singleplayer, if you punch a wild wolf and leave its field of vision, it will stare at you and not move at all. Going back into its range will make it continue pursuing you.
 * Aggressive wolves have the path-finding of most mobs, such as going around pits, but may sometimes try to jump to get a player that's separated by a 1-2 block gap. In two block gaps, they won't make the jump and fall, but may manage to damage the player.
 * Killing your own tamed wolves will still make them drop experience.
 * In Xbox 360 and PS3 edition you can only have 1-8 wolves at a time and in the PS4 and Xbox One edition you can only have 1-16 at a time.
 * Untamed wolves use their hostile appearance when they are attacking sheep, skeletons, or rabbits. They will change back once the targeted mob dies or gets out of their range.
 * Attacking a wild wolf on peaceful won't damage you, but they assume the hostile appearance and try to push you, similar to a baby slime.
 * A wild baby wolf's head grows significantly when attacked.
 * If the player attacks a wolf, but then moves a large distance away (e.g. 70 blocks), the wolf will still appear hostile but will exhibit neutral behavior
