RE: Sportdog 1200
well sorry Mite to take over your post, but this is better than starting a new one. today i used it a little on him. mine has 6 levels. it took him to number 3 for him to even feel it. and 3 is a pretty good zap. but i put him on a 20' lead and let him out and called "here" and he didnt listen(he knows what here is, just started a few weeks ago that he would stop listening to me) and i said "here" again and zap and so on till he came in, then i told him good boy. seemed to work only did it a few times and called it quits for the day.
