Harness Lead is a leash and harness in one that reduces pulling on most and is escape resistant. It is made of double braided nylon and has a strength of 4,000 lbs. Hand crafted in USA. Harness Lead must be used properly, according to instructions, to be escape proof. It is not to be used for tie out unattended. Harness Lead is NOT CHEW PROOF. 

TIP: Once you properly fit Harness Lead to dog and you begin the walk, you will notice the rubber disc will rise in air. This is correct. The RUBBER DISC is there to prevent over loosening. Rubber disc acts as a "floater". Allow the RUBBER DISC to RISE and FALL naturally. Do not continue to push rubber disc down as you walk, this will keep leash tight on dog.
