I think it's great if you can do that with your horse, you're very lucky but for me, safety comes first. Not so much for the liberty training but the tackles riding. There are so many things that can happen that could be avoided from using the correct equipment. Not all the time may I add & I take my hat off to those who do it!
I think it's awesome and totally freeing
Ohh it's really good for the horse and makes them more focused on anything. They'll trust you more if you do it.
