I got my horse eclipse a year and a half ago (a month before my 4H show season started). I had got him from the race track after he had been beaten and abused. Only worked with him for a month on trust and behavior as well as getting him ready to go to the shows and he had gotten first and second place most of the time. our barn closed so we moved and the new barn wasn't feeding him so we moved 3 months after we got there due to him trying to throw me off evertime i got on and him not being fed. the barn we have been at for a year now has been perfect and he had made progress evan though he didnt place at the shows (but its not about winning or the ribbons so it didnt bother me) but now he has been trying to throw me off all the time but only at the canter. i really need help before someone gets hurt and my parents have to sell him. even my trainer has tryed all sorts of stuff to get him to behave but she cant figure it out either and I'm only 14 and really really dont want my parents to sell him he means everything to me and Ive been riding for 8 years and am at the barn 4 times a week. i try new things everytime but nothing is working im even gonna have a woman i know come do theareplate with him and if that dosent help my vet said she can do ciropracting on him she went to school for that. I NEED ALL THE ADVICE I CAN GET.
