I've read all your questions and I honestly think you have to start at zero. Your horse doesn't have any reason to trust humans at all. Therefore you should start with groundwork to build trust and your horses self-esteem.
With that backstory in mind you should make your time with loading her on a trailer. When you have build enough trust she won't be so worried anymore. Trust me, my horse was so afraid of the trailer that he destroyed the one of his former owner, while driving. But we started with just standing near the trailer and making it a relaxing point. Reading next to it while the ramp is open and eventually started to gave him the idea to explore it. As soon as he sniffed the ramp we rewarded him.
Next time we started annoying him by lightly tipping his hindend with the end of the rope till he walked one step on the ramp. Then rewarded him again with a little pause and then started annoying him again. It took a lot of time but with this technic he learned to walk in the trailer and see it as a kind of savezone. Wenn trained circa two days a week for three weeks and he started self-loading like he never had an accident. And when your horse dose that you should make regularly little Trip's so she learns that she canes back home and is not going back to the slaughterhouse. And when she recognizes that you don't leave her side that builds a lot of trust as well.
Hope this helps..
It could be that.. I will probably wait a little bit longer before doing anything for ulcers because the past week or so she has been a bit better (but still barely trotting). Thank you though!! I’m so glad I found this website! Everyone is so nice and I got way more responses than I thought I would!
less is more is definitely true for her. For the few times that she does go, it’s with a gentle squeeze. If you do more of a kick she just stops!
sounds like mine. less is more with her and i have to play around with the pressure each day to find what she’s most comfortable with every rid
I know two diseases that has affect on performance and it's Equine Azoturia:
It can happen suddenly when exercising and the horse is unwilling to go, the muscles of the hind-quarters feel hot and hard, amd sometimes it might be confused with colic and horse might even struggle to stand
And the other one is Equine Rhabdomyolysis:
It's when muscles are strained, over feeding with carbohydrates, vitamin E and selenium. Also not warming up and cooling down properly
Horse will be firm and painful over the lumbar and regions of topline
Maybe some rehabilitation and relaxing manage would help your horse bcos it actually can be something to do with her muscles in her hind quarters and top line
There was a horse like this at my old barn. I’m not sure what the disease was called, but it has to do with their muscles, not their stomach. I’d look into diseases and conditions of the muscle!
She is a rescue, so we don't know her past or what she did. She was clearly trained and had been ridden before. When she got here we fed her grain which most of the horses at the barn get. We added a Smartpak for her hooves which definitely helped. After about 2 months of riding her, she started to not want to move at all! Even asking her to walk was a challenge. We had our vet come to test for lyme, it came back positive. The doxycycline bothered her stomach, so we then added the aloe. She is off doxy now, but we switched to another vet to see what was going on with her. When they came they said she should get shoes, and she is vitamin E deficient. They said her diet is fine, and adding the vitamin E supplement shouldn't effect her. So her diet now is Nutrena ProForce Fuel, Smartpak supplement, Vit. E, tiny bit of aloe. I can ask my trainer what she thinks about her diet and maybe I can change some things around.
To answer the other questions:
She literally has days where she will not move. She will walk slowly but will not trot or even walk faster. I can't use a whip because she stops and bucks if I do. I don't use it to actually hit her hard, just a light tap. Recently, she has been a little bit better at trotting but my instructor has to follow next to us with a lunge whip.
She has been like this for a few months now. At fist we thought it was her lyme, then we thought it was her stomach from the med, and then we thought it was her hooves.
She mainly lives outdoors in a paddock by herself, but if it is raining, snowing, or really cold out she goes in her stall.
I have tried a lot of groundwork. My instructor is really into it and does clinics so she shows me how to do a lot of things. Sweetie is very responsive on the ground with groundwork. She is also great at lunging.
Sorry this is so long! I would have put it in the question but I couldn't fit it. Thank you so much for your info and opinions. I will probably see a chiropractor sometime and see if that helps.
Get her checked by a qualified horse chiropractor/phsyio. Also checked by vet. She could be grass affected
Have you composed this diet yourself? If so I'd recommend asking some nutritionist to make her a diet. I'm not saying what you said is wrong but it sounds like you're giving her a lot of different things and sometimes there are things that are not working well when given together and we might not even realise.
Is she not moving at all or is she just slow /lazy?
How long has she been behaving like this for?
Is she living out or indoors?
How long have you had her for and what is her experience from past?
There are much more things that need to be taken under consideration than just diet.
Try some bonding exercises (ground work). There is a lot of videos on fb of trainers with great advice and are working with different types of horses.
