A dog leash supporting clamp system including a clamping member having a threaded aperture for receiving a threaded screw and a 360-degree rotatable swivel clip. The clamping member includes an open-end for securing the clamp assembly to an edge of a flat surfaced item such as a table or chair. The threaded screw is able to be tightened within the threaded aperture via a handle, thereby closing a gap between a top-portion and a bottom-portion of the clamping member to clamp to the edge of the flat surfaced item. The clip is affixed to the threaded screw and may removably receive a pet leash and support the pet leash at an adjustable length.
