A while back, I decided to chain together 3 tricks: sit pretty, down, and play dead. I wanted to combine them into one big trick with the verbal/hand cues for freeze, bang, and you're dead. Brody picked them up pretty quickly, but I never really got the cues as clean as I wanted, so I put the trick aside for a while. Later, I wanted to teach roll over and roll back, which he has been really reluctant to do for some reason. He knows the hand and verbal cues for both, but will try to wait me out on doing them, hoping I will just forget and move on to something else. He's getting better, but I have to out-stubborn him most of the time. The problem is, I want to go back to the old chain, but he won't stop at "dead", he rolls over. I need to fix my hand cue for dead and/or roll over so that they are clear and distinct. Any ideas?
