Abstract: An extensible elastic leash attenuates physical forces generated between the pet and the owner. The leash tempers the impulse forces and makes them more manageable, allowing both the owner and the pet to walk and run without discomfiture. This leash has both elastic and non-elastic members, the elastic member is parallel to a first non-elastic member and when the elastic member is at its full extension the length of the elastic member and the parallel first non-elastic member are the same. The elastic member is further connected to a second non-elastic member which is elongated and has a clip at its distal end to connect to the collar of a pet.
