Lead

Leads, also known as leashes, are items used to leash and lead passive mobs and utility mobs.

Mobs
Wandering traders drop 2 leads when detached from trader llamas.

Leashing mobs


a lead on a mob ties the lead to the mob, allowing it to be moved by the player. Multiple mobs can be held by leads at once, but each mob held requires its own lead.

It is possible to leash the following mobs: • Bee

• Cat

• Chicken

• Cow

• Dolphin

• Donkey

• Fox

• Iron golem

• Llama (including Trader Llama)

• Mooshroom (both variants)

• Horse

• Mule

• Ocelot ‌

• Parrot

• Pig

• Polar bear

• Rabbit

• Sheep

• Squid

• Snow Golem

• Wolf Additionally, villagers, wandering trader and hostile mobs can be leashed using a map or NBT editor.

With a mob on a lead held by the player, the lead on any type of fence (not wall) attachs the lead to the fence with a visible knot, tying the mob to the fence. Multiple leads may be attached to one fence post. A mob tied to a fence tends to stay within 5 blocks of the fence post.

A lead can also be attached to a boat.

A lead is broken by pressing the control on the mob again, hitting the knot, or removing the attached fence post. Leads also break when hit by arrows. Whenever a lead is removed or broken, it drops as an item at the location of the mob – except if pressing use item control on the mob in Creative mode. A lead does not break if the attached animal dies.

A lead can stretch a maximum of 10 blocks before breaking.

A lead does not prevent mobs from despawning, if they normally would despawn.

If the player walks into and back out of a nether portal while holding a lead connected to a mob, the lead remains attached to the mob. However, if a mob attached to a lead walks into a nether portal, the lead breaks and drops as items in the other dimension.

A lead can be used to remove a mob from a boat without needing to break the boat, if the mob is compatible with the lead.

If a chunk unloads while containing a leashed mob (either by the player walking too far away, or traveling to another dimension via portal), the lead breaks and drops as an item, leaving the mob free to wander around.

Data values
Lead knots have entity data that define various properties of the entity.

Trivia

 * The lead is named as “leash” in the texture file.
 * If a player goes to sleep while holding a mob on a lead, the lead remains attached.
 * If the player attempts to land after flying on Creative mode with a mob leashed, the mob takes damage as if it fell (with the exception of ocelots, snow golems, cats, iron golems, parrots and chickens) unless under slow falling effect or it lands on a slime block or in water.
 * When using the /replaceitem to put a lead in a player's head slot, it looks like the player is wearing a monocle.
