This rear shock absorber makes for lively dogs really sense! It protects both human and dog and makes pulling dogs while walking a little more bearable. However, note the length of the damper - in combination with some (Flexi) Linen (or if he does not at harness but to a collar "between hanged" is) the dogs get tangled very quickly while running, since the damper but some has its own weight and the whole team pulls down a bit. Furthermore, I doubt the longevity of the product should also times longer distances fro fully extended before a dog like mine (27kg Rottweiler-Labrador dog). He leiert time something out but what is not surprising under continuous load and the extent of Ausleierns in aktzeptablen range.
