Ok we have already had her saddle fitting checked and a chiropractor check on her and a Dentist come and see. She does it all the time at the house too and Im calm when I ride her never really worked up. She does it different times. She has more of a rearing habit though but I don't need help on that. I don't like people telling me how too handle my horse when it comes too rearing because kicking her or turning her and stuff doesnt work on her when she rears she tends too go over backwards if you kick or turn her while she rears.
