I got her as a year old. We had a really good bond when I broke her. She did great! She was doing fantastic till several months ago. We were taking our weekly lesson and it was time to canter. She blew up! Ever since then she has always don't it at the canter. Every one keeps telling me the only thing to help her is to ride. But I ride her all time. I ride 2 times a week and lunge every other day. Am I doing some thing wrong? Should I send her to a profeshional? It really upsets me because she is my first horse and my only horse. Its really embarosing when I have to tell people that we can't canter on the trails because of her behavior. So I stop trail riding.Please help I want to be happy to ride her again I don't want to feel like its a chore.
