So my horse Sheena literally will trot backwards and I am stumped by how to correct this. She does not pay attention to where she is going and will run backwards for as long as she can. The last time she did it, I tried to send her forward with my leg and she reared up instead :/ I am pretty sure it is out of fear/excitement and not out of pain. She has had her teeth done, doesn't seem to have back pain, and I have checked her tack. I don't think it is the bit because she did it once when I was riding bareback in a halter. Anyways she does not do this often, but these are some of the times when it has happened:
A.) We were trail riding and had to cross over a bridge. Sheena didn't want to go over it so another horse went first, and when she thought she was being left behind she started trotting backwards. (Doesn't make sense since you would think she would want to go towards the horse)
B.) We were in the ring messing around with mounted games. We were doing a relay and I had to make Sheena wait behind a cone for the other rider to come back and pass me the stick. She was excited and when I didn't let her go forward she started trotting backwards instead.
C.) I was on a trial ride by myself and Sheena was scared to go through a narrow section of trail so she started trotting backwards.
D.) We were on a trial ride in a large group and we all stopped at a intersection to decide which way we would go. There was one horse behind us, and when we started moving again, the horse behind us walked ahead of Sheena. Sheena started running backwards, almost into a tree, and when I kicked her she reared up.
She has done this other times, but it is pretty much always when she feels she is being left behind. What should I do when she does this? I can't always be in the lead on trails because my friends horses are much worse when in the rear. Now I'm worried every time she runs backwards she will rear. This was the first time I had ever had her rear. Any suggestions?
