What is a Pet Retractable Leash?

A pet retractable leash is a type of leash that allows the user to adjust the length of the leash, giving the pet more freedom to roam while still under control. The leash typically consists of a thin cord wound around a spring-loaded device housed in a plastic handle. The handle has a mechanism that allows the user to lock the leash at a desired length or release it to let the pet move further away.
