Although ponying is wonderful for training, there are some things about it that if you've never done it before you'd want someone to point out any thing you should be careful about, for safety sake.
Also, I don't know if the OP has a second horse to pony from. Dunno.
I think that Elana said it well, and some others too. Get forward movement at walk, don't work in small circles yet and maybe use another horse or human to inspire the hrose to move forward.
Marecare would you like to explain to us any pointers on ponying; I.e Things you don't do (dangerous) and things you do. I would love to learn any tips. I think it's a great thing to know how to do, and I've nver done it. Never had a need to .
Thank you and I realize that I live in an area where this has been practiced for a very long time and what is very common for us might be strange for others.
The lead horse has to be chosen and matched to fit the training and sometimes a good place to start is just having the young horse in a pen next to the older one.
Some cases a handler might put them in together for a bit so that they can kind of work it out.
I would suggest that a person that has not done this before not wrap or dally the lead rope around the horn or tie it on to anything.
The lead horse may become a bit irritated with the young horses lack of enthusiasm and squeal,cow kick,or nip,so a handler should always be on the lookout for bad behavior.
Think of it like a very small trail ride that might only last 10 minutes.
It is best to start out in a small pen and not get all hung up about the lead rope at first.
Just with being there with a second horse will inspire more movement from the young one in most cases.
If there is any nervousness the young one will lock on (just like they do in the herd) and track right along to gain comfort.
The young horse will aquaint themselves with seeing a rider above them if they have not been ridden yet and the second rider can "Circle up"
(just like they do in a herd)the young one if you are riding the young one for the first time and loose some directional control.
