US Patent 8256385 Dual retractable pet leash with ability to stop pets individually

A twin pet leash prevents tangling by permitting the reel portion to rotate relative to the handle portion, and features individually controllable leash stop mechanisms. Even while an individual leash is stopped, the reel portion can rotate relative to the handle portion so that tangling of the pet leashes is avoided. The leash handle portion has two triggers which are color coded to match the color of the leash, so that a user can readily identify which of the two leashes are to be stopped. Either or both of the leashes can be stopped or released, without interfering with the operation of the other one of the leashes.
