I'll search for that thread. You are right that the momentary is shorter, and you can't exactly replicate it on continuous. I guess I thought that they might be so close as to be really indistinguishable to the dog.
I have had problems with my dog on a slow/loopy sit, and I was taught to give him a whistle and then a continuous until his butt hit the ground. It clears him right up when he takes a notion to try it again. Have I been doing this incorrectly all this time or is this one of those "it works for that particular dog" things?
Thanks for the response. The more I learn the more I see I have to learn.
