i have had my horse since i was 6. i have had 3 trainers in total and the third one broke him completely. he tugged on his mouth, he made him strong and jumped him more than that horse actually can bear. i have been 2 months not being able to jump him more than a meter without him running off. what should i do? i have tried everything: dressage... show eason is coming up and i really want to compete but how? should i just sell him?
