Replacement Bungee Cord Ends
Pack Includes three (3) pieces of heavy-duty bungee shock cord with a tensile strength 250 pounds
Can be kept on hand for replacements as needed or double up bungee ends for more resistance.
Use a fisherman's knot to secure to the harness.
Check the bungee on harnesses regularly for loose ends or ends getting shorter and if so re-tie, or as needed, replace with a new cord.
Retie/replace would individually depend on each harness' use, the amount of use, the time used on that bungee, as well as depend on the dog.
