Lead

Leads are items used to hitch animals to fence posts or nether brick fence posts, and also to lead them around.

Usage and behavior
Right-clicking on an animal with a lead in your hand will tie it to the animal, allowing you to lead that animal; right-clicking on the animal again will release it. You can use other inventory items while holding the lead, and you can lead multiple animals at once.

Once you have an animal on a lead, right-clicking onto a fence will attach any leads you are holding to the fence with a visible knot. Attacking the knot or removing the fence post removes the lead(s).

A lead will stretch a maximum of ten meters before breaking. Whenever a lead is removed or broken it will drop as an item at the location of the animal; it will not automatically return to your inventory.

Most passive mobs can be "leashed". These include: horses, wolves, cats, sheep, pigs, cows, mooshrooms, chickens, squid, Iron Golems, and Snow Golems. Bats are the only passive mob which cannot be attached to a lead, and any mobs which naturally despawn (such as squid) still despawn, even when they are.

Note that it is technically possible to attach hostile mobs to a lead, but only by modifying your region save files. Certain mobs, however (such as bats) as well as players, cannot be attached, even with this method.

Trivia

 * The lead can extend out to 5 blocks when tied between a fence post and a mob.
 * They are named as 'leash' in the texture file.
 * Untamed ocelots can be captured and tied up using a lead.
 * If you are in creative mode you can leash a mob and pull it into the air, or tie it to a high up fence post (see picture below).
 * Multiple mobs can be tied to the same fence post.
 * You can use the lead to capture several mobs at the same time and walk them around altogether.
 * There is no known way of crafting them as of yet.
