Anyone have any tips...because it's not working real well. I'm trying to teach Veronica to shake (as in a full body shake off) and I've been at it for awhile...every time she does it either click & treat if I'm prepared or "yes" mark and "good girl" scratch on the head if I'm not prepared. I always follow it with "good shake"...because I'm not sure when to introduce the cue since she's not offering the behavior other than when it's naturally occurring. But for all my clicking and "yes"ing; saying "shake" is getting me a blank look followed by an effort to offer other unrelated behaviors. Any ideas?
