The term 'obedience school item' can be summarized as a LEASH, which is a five-letter word. A LEASH is a rope or strap that is used to control or lead an animal, usually a dog. It is commonly used in obedience schools to help teach the animal to obey commands and stay close to its handler. Leashes are also used for safety purposes, such as keeping a pet from running away or getting into dangerous situations.
