We have designed a double-duty dog leash.  What makes it different is it has a swivel on the handle of the leash so it doesn't tangle when your dog runs around you.  It also has a short-crowd control- leash on the end that hooks to the dog.  My concern is "How strong is your webbing as far as a large strong dog (pit, shepherd, etc.) might lunge. Please send sample to the Florida address.  Thanks,  Debra
