US Patent 7757639 Pet leash assembly

A pet leash assembly includes a primary leash with axially opposed looped ends, and a first ring member slidably conjoined to one of the looped ends. Auxiliary leashes including first and second locking members positioned at opposed ends thereof, and a second ring member are removably mated with a top one of the locking members of the auxiliary leashes. The auxiliary leashes are independently removable from the second ring member. A mechanism rotatably anchors the first and second ring members so that the auxiliary leashes remain spaced apart along unique travel paths while the pets cross over an adjoining one of the travel paths.
