This is more than probably pain related, have you consulted a vet? You could try the bute test, give her the recommended dose for 3 days and see if she moves forward. If she does, you have your answer, it’s pain that is causing her issues. BUT, you need a vet to prescribe bute.
Sometimes you just have to push through the the bucking. It could just be her testing you
Or they are just bad behaved so you should have a look at Exercises and trainings for horses that are bucking.
Well this sounds a bit complicated. When horse is refusing to go forward by bucking it usually means they're either in pain or whatever they are fed makes them go fizzy. Could you tell me what exactly your gets to eat daily?
Ah okay. Well I think when you stop her bucking then asking her to go forward will become easier. I still don't think any feed will make her more forward.
that's not what I meant Its not to stop her bucking if youd read it it's to make her what to go forward a bit and no I haven't let her away with it she's greens she's gonna do I just have to get her out of it she was like that when I got her 2 months ago so not my problem
Do you mean bute? As in pain medication?
To me it sounds like a training issue if pain has been ruled out. She obviously doesn't want to go forward so she protests and has gotten away with it so has become habit.
I would doubt any food will change her mind unless you stick a carrot on a stick over her head while riding 😂
