I can't believe it has been so long since I last posted on this subject! I use the remote collar every day to exercise my dog. I learned a lot from Robin and her associates, and I went back last year for a refresher course. We have also attended some of the afternoon classes, mostly just for socializing. She usually has some kind of dog walks each week, anyone can attend.
I would recommend Robin and her staff for any issues that anyone might be having with their dog. The e collar is just another tool, I don't consider it a "last resort" measure at all.
