Correct aids for Turn on Haunches

[winnieandben]

Please can someone tell me the correct aids for turn on the haunches both in hand and ridden and any tips on how to get it started ridden please?

It is in a dressage test I am doing this month (Interdressage) I have previously done a little in hand with her just using my hand on her shoulder to give her the idea.

Thank you

I'd be interested to know too.  The horse I used to ride in lessons (many moons ago!) used to do TOH by using your outside toe just behind the elbow

I'd be interested in the proper aids too - I use open inside rein, indirect outside rein and outside knee on the saddle, seems to work but I'm sure it's not classical!
For ground work I hold the halter rope lightly against the neck with a little bend away and walk towards the opposite forefoot.

Anyone else any other ideas?

I was taught weight slightly back, outside leg behind the girth, open inside hand, indirect outside rein (and blocking forward movement). Again - has worked very effectively with every horse I've used it on, including those that are relatively unschooled.

This is what i decided to try as it seemed logical to me - and it worked 

Thanks for the input ladies
