A double dog run system utilizes a system of uniquely configured swivel members attached via a ground anchor to a container with sloped surfaces. Two dog leashes are connected to the swivel members by rotatable clamp members. The resulting system causes separation of the leashes when they are crossed, and compels the leashes to slide down the sloped surface of the container to the ground. The system guarantees that the leashes will never tangle, regardless of the speed and direction of movement of the dogs attached at the other ends of the leashes.
