Well, you've certainly come to the right place for advice no matter where you live. I'm slap ate up with advice. I give advice to folks all around the world. I'm just oozing advice from every pore. Hopefully, some of it may even be helpful.
Let's see if we have any helpful advice for you.
Without being there and seeing what is going on, let's see if perhaps I may be of some assistance.
Never heard of that classification before, not that means anything. One usually expects that breed to be much smaller.
I believe you are the first person I've ever heard from, and I've heard from a LOT of folks, who made an effort to make sure the saddle they bought actually fit the horse. Good!
Okay, here we go, bearing in mind for the most part I'm not there...
First of all, horses are the most compliant animals on earth. Whenever a perfectly usable horse abruptly becomes unusable I ALWAYS look for a physical issue.
Whenever a horse suddenly becomes abnormally spooky ("he's afraid of everything") the first place I look to is cervical subluxations. The neck gets injured in some manner, it can happen pretty much anyway you can think of, sudden head movement, rolling, playing with another horse and so on.
The result is a stiff neck.
When you have a stiff neck and you need to look at something off to the side you carefully turn your whole body to look at it.
When a horse needs to look at something off to the side, being an instinctual prey animal, it has to look fast to lessen its chances of being lunch. Since it can't look by just bending his neck because of a stiff neck it has to turn his whole body as well. Does that sound like something your horse does?
When a human with a stiff neck turns his whole body his pivot radius from center to outside is about a foot. The horse's pivot radius is about four feet. The parts of the body out at the end of the pivot radius move at a tremendously amplified speed. If you are sitting on the horse, the farther you are away from the horse's rotational center, the front legs, the more centrifugal force you experience. It's a little more involved than that but that's roughly the idea. A spooked, rapidly rotating, spinning, horse is not fun to be on.
But that's if he chooses or is able to turn and look. Most of the time the horse doesn't look because it is easier to just leave in a big hurry.
Horses evaluate spooks all the time. There are a number of criteria that determine their reaction to the spook. The one used most often is simply looking. Stiff necked horses have a hard time looking around.
Here's where I tell you the first thing I do when working with abnormally spooky horses is to have it examined by an equine chiropractor. If a horse has subluxated vertebrae, and a very high percentage of abnormally spooky horses do, an equine chiro can very often address the problem.
If you do not know of an equine chiro in your area you may be able to find one at http://AVCADoctors.com
Now we come to your daughter's fear...
Fear is always resolved by information. The more we learn about something the less we fear it. The more we learn about something the greater our options are for resolving the fear.
When the chiro points out his problems and your daughter sees what they are (I'm sure there'll be some) and sees them addressed it may help her some.
And then there is the "lunging" thing. Longeing a horse will not bleed off its energy. It will increase it if the intent is to bleed it off. As the horse becomes more and more conditioned its energy will increase.
Longeing a horse is, first of all, to teach it to pay attention to the handler and secondly, to build communication between horse and handler. When done properly your daughter will learn to control the horse from the ground which will give her better control from the saddle.
I would suggest your daughter go to the edge of her fear and when she is comfortable there go slightly beyond it and then go back to her comfort zone.
We have horses here who have been in the pastures pretty much unhandled for years except to vet them, trim them and feed them. Upholsterers have the rattiest furniture, mechanics have the rattiest cars, horse trainers own untrained unused horses because they are so busy with other people's horses. I have never heard one of them say, "I'm not living up to my potential!" or "I'm being wasted!" or "I need a job!" If they are unhappy spending their days eating and drinking I have never seen any sign of it.
Let me know what the chiro says. And then I'll give you some "where you can go from here" advice.
Best to you.
