Wow, with that video, I really don't like how she's being ridden. Way too far behind the vertical, completely discombobulated at the lope, strung out and heavy on the forehand, and either the rider is horrible or she rides really rough at the trot. Her lope doesn't look that bumpy under saddle but everything else would make me avoid her.
They've got her head basically tied down to her chest by some kind of martingale/training fork thing and there were several times that I can see she would have been carrying her head like a giraffe if it hadn't been tied down. She looks like she may have a bit of potential but she's going to need some serious re-training before it will begin to show at all. Truthfully, for more than a couple of hundred, she's probably going to be more trouble than she's worth. Especially if you don't have the training experience to start her over and bring her along correctly.
SM..You that video of her when she was younger--she didnt use to carry her head too high. I mean, she's 3/4 arab..of course she's going to have some elevation to her headset, but she just looks off in this video. She doesnt get ridden regularly, and I know they have had kids on her mostly.
What do you think she needs in the way of retraining? Nothing a daily lunge and trail ride and arena work without a martinggale can't fix?
Is 500 too much for a horse with her...stuff?
I would mostly use her for trails and arena work (I'm not the most experienced rider, either, based on my posts. I know a great deal more than I did when I started, I don't get taken advantage of, and I ride an arab 4 times a week, im getting pretty good at predicting the fights and working them out). Arena work being playing with running poles, barrels, and maybe eventually jumping (which she does).
