Hi, I have a couple Welsh Pony fillies whom I’ve had since they were born - 3yo & 2yo. The 3-yo knows me very well. I’ve halter broke her and got her desensitized to picking up feet and objects like saddle blankets and bareback pads.  I’ve tried starting her myself but the problem I am having is I can’t get her to move. I’ve tried flapping & flapping, progressively waiving the flag & whip harder and harder, even snapping her a bit on the backside over & over and only at that point will she just give me a little side eye and so then I let up on the pressure to reward her but then she just goes back to whatever she’s interested in. It’s only when I turn to walk away from her completely, then she gives me her full attention and comes up and tries to rest her head on my shoulder. I think she may be too familiar with me. Do you have any suggestions for how I can get her to move away from my pressure?
