The second leash section is longer than the unextended first leash section. The first leash section's first end is configured to couple to or near the second leash section's first end. The first leash section's second end is configured to couple to a harness at a location on top of a dog. The second leash section's second end is configured to couple to a harness at a front location of the dog. The lengths of the first and second leash sections are configured so the first leash section extends when a dog pulls on the leash until the second leash section becomes taut. Once the second leash section becomes taut, a lateral force is generated on the dog to pull the dog laterally. Numerous other embodiments are provided. ## Claims ### Claim 1 A reduced-pull leash device for coupling to a leash comprising: a first leash section that is extendible, the first leash section having a length, a first end and a second end; and a second leash section, the second leash section having a length, a first end and a second end; wherein the length of the second leash section is longer than the length of the first leash section while the first leash section is unextended; wherein the first end of the first leash section and the first end of the second leash section are configured to couple to an end of a leash; wherein the second end of the first leash section is configured to couple to a dog harness at a location on top of a dog; wherein the second end of the second leash section is configured to couple to a dog harness at a front location of the dog; wherein the length of the first leash section and the length of the second leash section are configured so that the first leash section extends when a dog pulls on the leash until the second leash section becomes taut; and wherein once the second leash section becomes taut, a lateral force is generated at the front location of the dog by the second leash section so as to pull the dog laterally. ### Claim 2 (depends on 1) The leash device of claim 1 wherein the second leash section is not extendible. ### Claim 3 (depends on 1) The leash device of claim 1 wherein the second leash section is extendible but requires more force than the first leash section to extend. ### Claim 4 (depends on 1) The leash device of claim 1 further comprising a third leash section, the third leash section having a first end and a second end, wherein the first end of the third leash section is configured to couple to the dog harness at a location on top of the dog and the second end of the third leash section is configured to couple to the second leash section. ### Claim 5 (depends on 1) The leash device of claim 1 wherein the first leash section includes at least one bungee cord. ### Claim 6 (depends on 1) The leash device of claim 1 further comprising an additional mounting piece that couples between the dog harness and the second end of the second leash section so as to increase the rotational torque exerted on the dog by the second leash section during pulling by the dog. ### Claim 7 (depends on 6) The leash device of claim 6 wherein the additional mounting piece includes a pull-activated alarm. ### Claim 8 (depends on 6) The leash device of claim 6 wherein the additional mounting piece includes a pull-activated vibration mechanism. ### Claim 9 (depends on 6) The leash device of claim 6 wherein the additional mounting piece includes a pull-activated shock mechanism. ### Claim 10 (depends on 1) The reduced-pull leash device of claim 1 wherein the first leash section comprises rubber. ### Claim 11 (depends on 1) The reduced-pull leash device of claim 1 wherein the second leash section comprises nylon. ### Claim 12 (depends on 1) The reduced-pull leash device of claim 1 wherein the first leash section has an unextended length that is ½ to ¾ of a length of the second leash section. ### Claim 13 (depends on 1) The reduced-pull leash device of claim 1 wherein the first leash section has an unextended length of 5-15 inches. ### Claim 14 (depends on 13) The reduced-pull leash device of claim 13 wherein the first leash section has an unextended length of 8-12 inches. ### Claim 15 (depends on 1) The reduced-pull leash device of claim 1 wherein the second leash section has a length of 15-30 inches. ### Claim 16 (depends on 15) The reduced-pull leash device of claim 15 wherein the second leash section has a length of 18-25 inches. ### Claim 17 (depends on 1) The reduced-pull leash device of claim 1 further comprising a coupling device and wherein the first end of the first leash section and the first end of the second leash section are configured to couple to the end of the leash via the coupling device. ### Claim 18 (depends on 17) The reduced-pull leash device of claim 17 wherein the coupling device is a ring.
