We use 3/4" polypro webbing for this series. Since it is lighter than the nylon, it is a good choice for smaller as well as larger dogs. This is the lightweight polypro and is available in a wide array of colors. This leash is not recommended for tying up your dog because the abrasion resistance is not that great. If you are wanting something tough, go for the flat nylon! We manufacture our leashes to your specifications, for example, if you order a 6' leash: it will measure 6' from tip of webbing to end of handle, and the handle has a 8" open loop. All of our Collars and Leashes are proudly made in the U.S.A by: A division of Strapworks LLC
