Oh, I totally agree, Jess. I didn't mean to imply that you or anyone here who uses prongs puts their dogs through true "pain"... but, it obviously causes discomfort, or it wouldn't have any affect.

I think it is a tool that should be used as a last resort, that's just my opinion, though. And, honestly, I don't think a pet store or a busy shopping area is the ideal place to start prong training. Instead, the backyard would be a good place, or anywhere devoid of anything that the dog could associate the discomfort with, besides pulling.
