A Leash is a length of cord, chain, leather or synthetic material connecting a Pet's collar or harness to their Handler. Leashes serve practical, symbolic and ceremonial functions, ranging from a light guide at a social event to a central element of a scene.

The Leash is one of the oldest and most widely used pieces of Petplay equipment, adapted from real-world companion-animal practice.

Leash etiquette varies by community. Many spaces treat leading a Pet on a leash as a shared social act with its own courtesies.
