I love the lupine leashes. They are the best product on the market b/c of their guarantee. They guarantee they won’t fade, rip or they will replace them. And the padded lupine leash is so comfortable on your hand.
I just use the cotton leadshank/ or lead rope that I use for horses as a leash, pretty much the same thing, and a little bit cheaper!
But I use it for bigger, stronger dogs like the pits, or the great danes 'cause the leadshanks get awefully thick.
My favorite leashes are customized ones from strapworks dot com. You can select the material and pattern for the leash (including splitters) and then customize the metal hardware.
It's the best site I've found so far for leashes that are durable and don't get sand and debris stuck in the latches after romps on the beach. I have 3 and they are pretty indestructable. Highly recommended by this dog lady!
