For my two pennies worth.1) A rope or leather slip with an added bit of rope/leather to slip over your shoulder. 2) Harness bought offf eBay, sorry cannot remember the name but I care very much about the comfort of my dog whilst it is on her. It is made of neoprene and has orange braiding around it, a top ring for tracking lead attachment and cost the princely sum of £24.99. 3)Tracking lead. Biothane orange, 10 meters £18.99, I think that was off a company called K9.
So in brief there is no need to spend loads of dough on Niggelough and all that crap. Buy something like my little set up and have a nice days stalking or a few beers on the savings.
