I got mine from FunStuffforDogs.com ā however, I can't find it on their site anymore. I did manage to find it several other places. This one was the cheapest and most closely resembles the one I have. I like this one because it has a loop for your hand for extra control. It also has some bungee material so IF your dog decides to go in a different direction from you, it's not as harsh on him. I also like it's designed with a little waist compartment that will hold my keys, cell phone, and doggie poop bags. I have to admit though-- if we're just walking, my dogs will sniff and get tangled up. I connect my two dogs on a leash splitter so they're both harnessed into the same unit. And for us, it works best if we are jogging or running. They LOVE it. If I get that thing out, they go nuts because they know what's coming. Let me know if anyone else tries this!!
