How do you train a girthy horse not to bite when you tighten the girth? I've tried ignoring her and I've tried popping her in the nose but nothing works. My horse will bite whoever she can reach when I tighten the girth, and if her head is tied too tight to reach me then she'll bite the fence. Tack fits fine though, and it can't be the tack because she does this with her english saddle, her western saddle, and her bareback pad. Yet she doesn't so much as blink when I tighten the girth while mounted.
