Dog Restrainers, such as LEASHES, are used to keep dogs under control and prevent them from running away. LEASHES are the most common type of dog restrainer, consisting of a length of material attached to a collar or harness that is held by the owner. Other types of dog restrainers include muzzles, head collars, and body harnesses. All of these tools are designed to provide a safe and secure way to keep dogs from running away or getting into trouble.
