To finish up second grade today, we had a little competition--who could do 'down from a distance' at the greatest distance, and Cleo won! I knew she could do it from a really long way away, but i wasn't sure how she'd do with all the other dogs around. One thing she does, though, is anticipate me. As soon as I walked away and stopped, before i could tell her what to do, she went into down position. When we practice at home, i mix it up and sometimes call her to come to me instead (or other things). What is the best way to make sure she waits for my instruction first?
