The term 'restricting leashes' can be summarized as the use of TETHERS to limit the movement of an animal. TETHERS, which are also known as leashes, are typically used to keep a pet or other animal in a certain area or to prevent them from running away. They are usually made of rope, chain, or leather and are attached to a collar or harness worn by the animal. The use of restricting leashes is a common practice for pet owners and is often used to ensure the safety of the animal.
