Well I think I got it!!!!!!!!!!
I was watching the two videos that was made of Sonny before I bought him and I thought I'd put my hands in the same position as the lady did.
I did it and it seemed that something was different about his gait...it seemed a tad stronger (even at his western jog) and also I seemed to be sitting up farther than I originally was...yet it seemed like his front was up higher than his back end.
So I think I got him to do it!!!!
I am going to do it again and have a friend comment to see if she thinks the back is rounded and also take a video so you all can decide if he looks rounded...but there was definitely some difference!!
I'm sooooo happy.
But with the position my hands are in I don't think I'd be able to show like that.
I found out that if I put my hands around my belly button and have my horizontal (like I usually have them) he hollows his back, brings his head up further and goes on the vertical (dressage collection I call it)...but if I put my hands down close to the pommel of the saddle and keep my hands vertical (I guess you'd consider it piano hands) he'll lower his neck, go on the vertical, and "hopefully" round his back
I'll let you all know how it goes tomorrow!!!
