F/U on the harness post last week. I looked at what I had and we have this one
http://www.amazon.com/gp/product/B0013K0H3QIt is supposed to deter the dog from pulling because when they pull it turns them to the side. I think it will fit Cash and we dont use it on our little pup so I will bring it tomorrow night and if you want it, it is all yours.
