Advice wanted
Looking for recommendations for school liveries/ or riders who will come out and work with a difficult horse, she can go days/weeks being well behaved but will sometimes rear (big rears) being handled and under saddle, she's quite powerful and I'm not strong/ confident enough to deal with it, and it's becoming more and more established. All back, saddle, teeth all checked and are fine been looked at by vet as well. She's a 15.2hh, 5 yo, kept near lenwade/badswell please comment recommendations/ if you can help.
