if you get trained to be a horse rider, they will tell you how a horse should stop backing up, but listen carefully and hope that you wont make a mistake.

horse riding is very dangerous
watch out
you can get paralized if you fall off in the wrong position.

be carefull and good luck

Open her up and remove reverse gear.....and do something about all the shite you lot leave on the road too!

Go back to basics. Teach her to relax and drop her head; work on what she does well so she's confident and ask for new things slowly. When she backs up get her going forward even if it's circling. Don't pull back - if she's stressed and nervous you'll teach her to rear and that's NOT acceptable. You have to engage her hindquarters and get forward motion...even if it's in a small circle. I would not advise riding away and coming back - for two reasons. 1 is some horses once turned away will bolt and you've created a runaway. 2 because in going away she's being rewarded for stopping and backing up by going away from what she doesn't like. Riding a small circle - with that forward motion - doesn't let her stop to back up or rear but also doesn't let her leave.
