This is a slip lead and a figure 8 training aid in one.

When using as a slip lead set the metal adjuster to the correct size for your dog to stop the lead from tightening and choking.

When used as a figure of 8 simply pull the lead through the metal adjuster and slide up over their snout. This works on a pressure and release system that humanly stops your dog from pulling.
