An animal leash includes a resilient elastomeric coil having a distal end and a proximal end, a resilient elastomeric distal lead attached to the distal end of the coil, a resilient elastomeric proximal lead attached to the proximal end of the coil, a distal swivel attached to the distal lead, a proximal swivel attached to the proximal lead, a spring clip coupled to the distal swivel, a cushioned handle and a coupling adjoining the handle to the proximal swivel. The coil and distal and proximal leads are configured to provide two modes of stretching, including a spring mode wherein the coil substantially linearly extends as increasing tensile force is applied, and a strain mode wherein the coil and distal and proximal leads are strained according to a modulus of elasticity. The swivels resist twisting. The handle provides a comfortable structure that can be gripped or worn as a wrist band. Additionally, excess cord may be wrapped around the cushioned handle without causing discomfort to the user. A supplemental handle may be disposed between the distal end of the coil and the proximal end of the clip.
