I remember taking Nara through obedience classes in VA and they would not allow prongs. At the time, Nara was still a puppy, and I wasn't using prongs. It wasn't until she grew older, matured and was big and strong and pulling on walks that we started with a prong per her breeders recommendation. This seemed to be the easy way out for us. I was against the use of prongs up until that point, but I tried the prong on myself before trying it on Nara. It didn't hurt, and once she was wearing it, the pulling stopped instantly. It was a "miracle." Over time, I realized the prong was a crutch, because as soon as it came off, Nara was smart enough to know it and resort back to her pulling ways. Teaching HEEL was a better option, and I also hired a positive reinforcement behaviorist to work with us. She was the one who recommended the Softouch Concepts no-pull Sensation and/or Sensible harness. I bought one for Paw Paw, our bred-to-pull Siberian Husky, and also one for Nara. So, like the "crutch" of a prong, the harness was also a crutch that worked when they wore it, but didn't work when they were back on a flat collar. Back to HEEL training.
