I have a 4yr old I have been on her for 1 1/2 years. She is smart but very dominate. Her trott is so rough I can hardly post longer than 50 strides and she will speed up or do a fast turn or slow down all of a sudden. I have been trotting for 2 to 3 hours 4 times a week and her trott doesn't get any better (I think it is getting worse). I though if we trotted enough it would fix itself as with other horses I've owned. I mostley use Clinton Anderson's method and I love the results but I have not seen him address this topic other then trott more!!!
Ant advise would be good
