I had this idea for a leash in 2009 when i went from having one dog to having two dogs. I knew there had to be a way to walk two dogs with one leash with no strain on the walker.  Below is what I came up with. I call it the "Slide Leash" because the metal ring allows the dogs to move in any direction or "slide" one way or the other. The only tension is on the dogs and not the walker.

Shipping and handling is $5.00
