I studied with Turid Rugaas in 2014-2015, which is when I learned about the Haqihana harness. I have been using them ever since. Mine have lasted through several dogs and are the best harness I've found, in terms of ease of use and apparent comfort (No way to ask my dogs, but they don't seem to mind putting them on!). I have successfully used them as No Pull harnesses simply by clipping the leash to the front ring that holds the straps together. But dogs tend to pull on them less than other harnesses anyway, another reason I think it is probably a more comfortable harness. Turid's thinking is that dogs will pull to try and get away from something causing them discomfort, not understanding that the pulling is increasing the discomfort!
