Basil boy..I am trying to understand what type of harness you are talking about. I have or maybe had (lost two leashes at the dogpark a few weeks ago, when son thought it fitting to fish with one and loose it, fish the first one out with the second one and loose it too..! )..any way..I have/had a leash that had a big metal loop by the collar that you threaded the leash after wrapping it around the body of the dog, so in essence it was a leash that could be used as a harness..is that what you are talking about?
I think so… but my sister has never used it as a leash and it's not one straight long rope it's two long parallel ropes when it's all undone... But maybe this would serve as the same thing?
