We have had some lovely walk this week, Buddy and I... Using the harness, I have loosened it and he has only scraped along one wall and I think that was in a "habit" manner. I can see the merit of being leashed trained NOT to pull in the long term, but in the short term it is so much better than feeling tearful and with no control. In the meanwhile my husband is using the collar and lead and heel approach. So my thoughts are dont feel guilty for taking the harness approach even if it is the easiest solution, as long as the dog seems confortable.
