-This is a high quality 100% black full grain leather lead, 4mm thick-3/4 in wide- 6ft long. With solid brass hooks and fittings, all have a good feel to them and a nice quality about them. The lead is hand-stitched and has a reflective belt in the handle. It also comes with a nice bag to keep the leash in or you can take it with you when you take your walks and keep your poop bags handy. -The difference between this lead and the other leads is this lead can be used in six different mulitple functions.It can be used as a regular leash, it can be used as a P-leash (where you ues the leash to attach around the neck instead of a collar), it can be used as a hands free leash where it goes around your waist and then attaches to the dog giving you complete control of your hands for training(hands free), or you can use it as a double leash and walk two dogs,a short leash or an adjustable leash. It can be used for small and large dogs. -I tested each of these different functions out extensively and am very happy to report that each one performed beyond my expectations. I have two dogs that are of different sizes that I used this leash on to see how it would perform, one weighing 45 lbs. and the other weighing 78 lbs. and this leash worked great with the both of them. It also did a great job when I used it with them as a double leash. This is a good Quality Leash that will save you money(This is like 5 leashs in one).
