something may be pinching her or something u can call ur vet and make an apt. w/ them w/ ur saddle on
This does sound like a saddle fit problem but might also be an alignment issue. I'd have the horse seen by an equine chiropractor.
Can someone tell me how to stop a 6 year old horse from bucking. I'll ride her she's fine I get back on after a break and she bucks till I fall off then stops. I've had her vet checked and saddle fits? Help
I used to ride a horse who would buck downhill. She did it because the saddle was hurting her shoulders. You should definitely check the fit.
