I bought something similar to the pessoa to use on my horse. I'm going up there today so i'll take the directions home with me and copy them and post them on here. I'm also going to take a video on how to put it on and adjust it. I'll give you the link when I have it all edited and uploaded.
I scanned in the directions I got with mine...
This side basically tells you about it, and it shows you where all the parts are.
This one shows all the different positions.
I would start off with the first one and slowly progress your way up to the desired head set and collection.
When I first got Vega used to it, I had her in her stall and just let her get used to everything on her (especially the bum strap) After that, when I had her out to lunge her with it, I walked next to her (that way in case something happened, i'd be right there) And then I asked her to go out and lunge. I would also suggest not having your lunge line attached to the bit because they already have stuff connected, that I feel there is no need to add more.
Just remember to progress slowly and not to do it for too long because it is working all of their muscles.
If you want me to, I can send those to you so you can print them out and everything.
I didn't realise this was ground work. I was expecting it to be a horsemanship program like parelli. I would love to see photos of this equipment on the horse.
Would also love to hear what kind of progress you guys see. Looks very interesting!
I took a video yesterday of me using mine (it's not the pessoa but does the same thing for $120 cheaper) The video is very bad, but i'll see if I could get a still of it and post it on here.
Already (and I've only used it 3 times) Vega has been reaching for the bit, engaging her hindquarters, and doesn't gape her mouth when there is pressure on the bit. ( something she used to do at the slightest amount of rein pressure on the bit) She doesn't have an extremely low head set, but it's a lot better than her nose being high in the air.
Jazzy has been using it longer than I have, and has moved up in it, so i'm sure she can tell you about the progress she's made with Jarred.
