She looks off on her front left, but it would be just the ground, it's very rough. I would not be lunging a horse in that round pen.
She doesn't really know how to lunge, she should not keep coming into the circle and then going out of the circle again. You need to really get on her when she comes into you like that. She has no form and no collection and needs tons of ground work.
Good luck with her. That 's great that you guys have improvment.
The ground was accually way 2 soft if just starting to dry up. She knows how to lunge I was asking for a change of direction when she came in threw the middle. Also she has no form or collection there because she was really panicky. Just before that she got tangled in the reins and poped her self in the mouth and it was a pretty bad morning but it got better as we went. Ill try and get a video of me riding her when she wants she can have nice form and collection
She's was always pretty dang full of her self, when I did get on her when she kept coming in she went into a full gallop.
HAF I'm really not trying to sound mean. But she did come into your personal space (moved into the circle) way more then once. I'm not saying this is a fault of yours but of the horses.
It's okay to admit that your horse has faults, I do all the time. Critical critique is very very important when training your horse. If you can't critique your own horse you are never going to be able to further their training.
For when she moves into while lunging:
-Get on her about it. Push her away (Not literally) If you have a whip bring it to her shoulder and push her back against the wall. If you don't use a whip then stomp you feet at her and walk towards her shoulder, letting her know that you want her out of your personal space. Just from the short video I can tell that Chance has no respect at all for you. When you are asking for a direction change she should also never turn her hindquarters into you. That is a huge sign of disrespect. She should turn into the circle always facing up with you. Have you ever tried join up with Chance. IMO It really does work wonders.
-I would start again with some ground driving. I teach almost all my collection from the ground before I ever get on their backs.
The next 2 things I would not recommend unless you have done them before and know exactly how to do them. They could both cause serious harm if not done exactly the right way. If you have not done them see if you can have someone (Other then your trainer, I really have nothing good to say about her...sorry) that has done it before come out and help you a few times.
-Tie your reins to a circingle, loose at first (while lunging her) and slowing and I mean slowly bring in the slack. Maybe half an inch at a time (It could take up to a month) until she has her head and neck in the proper form. NEVER EVER pull it right tight the fist time. You could really cause harm to your horse if you do this. Like I said bring it in slowly half an inch to an inch at time. And only tighten it if she stops fighting the pressure that is on there. This is very crucial to be very careful while doing this. Also you should only do this on level ground; if your horse does trip they really need their neck to keep themselves up.
-The other thing is draw reins, which work similar to what I described above.
One more tip!
Just a suggestion but you should bring your stirrups up when lunging her. They can move around alot and bang at her sides potentially hurting her. With your stirrups up you can still have your reins thru them.
1) Keep your stirrups run up while doing any ground-work.
2) The reins wrapped around the leathers like that just screams disaster.
3) She looks stiff on her left front and right hind - possibly in the stifles in the hind
4) Get after her when she comes into the circle.
5) Really really get after her when she changes direction and points her hindquarters to you - that is a BIG no-no.. get after her, make her work HARD for turning her hind end to you - when she turns her forequarter to you (but stays out on the circle) you can ease the pressure up. She should not change direction until you tell her to.
6) When the footing is bad, don't push her to canter - it's a very unbalanced gait - it was partly footing and partly horse being unbalanced that made her fall. It makes me very concerned about her fall - she didn't catch herself at all.. something isn't right with that, but I can't put my finger on it.
7) Speaking of balance - this is a major area in need of improvement. She needs to build up topline and become way more balanced.
I've thought on it and I know what made me get an odd feeling about the fall - it just wasn't right. She didn't put up ANY fight to try and stay up, she just gave in and fell. I'm wondering if she isn't in pain.. she looks off on the left front (shoulder maybe?) and hind right (stifle).
I would have loved to see how she got back up - if it was a struggle or not... I'd get a vet out to check on her, give her legs and back a good once-over.
Don't try and make a horse canter in slippery conditions... not when they're so unbalanced and sore that they can't properly catch themselves from falling.
