As for the method we're using, I tap her heel with a dressage whip and make a "donk" noise to associate to the action. She has begun executing the action simply with the "donk" for a cue, and only gets a treat every couple of times. The problem is when we try to incorporate forward motion with he exaggerated steps.
I was thinking maybe a visual cue, like lifting my own leg when I ask her to lift hers, and then start moving as if i"m doing the walk too? I saw this in a video, and it worked for the girl who made it, but i'm not sure it would work with anne. Any suggestions?
