It starts when I cinch him. He's always been cinch-y so I have to tighten in increments, groom a little, and tighten and so on. That's okay, I don't care that's not an issue. However, I am totally sick of cross ties. I want to tack him up just tying him to a regular tie so I can tack up ANYWHERE rather than just where I have cross ties. So I've been working on that and every time he spins into me I put two of my fingers against his flank and let him push into them and as soon as he feels the pressure it he steps promptly away. He's been getting better about standing still now but then my friend said I'm damaging his flank.
This is new to me. I'm not hard against it, and it's not like I'm punching it, I'm just letting him run into my fingers to persuade him to move away. Could I be hurting him? Is this an okay training method? He is learning quickly and he hardly does it now so I don't really have to do it but every once and a while he is extremely persistent. I also know its not his saddle, I had it checked by my trainer and she said it fits him great.
