A tether apparatus for connecting a dog to a bike for running with the bike. The tether comprises a continuously flexible wand with a bow-like curvature in a vertical plane and an S-curvature in a horizontal plane. The wand is attached to a bike frame at front and mid-points, and a tail end is spaced to the rear and side of the bike. The tail end includes a short vertical harness connector hanging freely from the tail end for vertical attachment to a dog's collar or harness from above. A dog is accordingly tethered under the tail end of the wand, spaced to the rear and side of the bike, with the flexible wand absorbing shock and load when the dog's position and speed differ relative to the bike.
