She has had saddle fitted, teeth checked, and has past a 5 stage vetting
She is not in any pain what so ever, yeah she keeps bucking and rearing.
She's worse when hacking out alone, she will randomly stop & when you try to get her to move she will either buck or rear.
Today I rode her out with two other people on their horses, we got to the bottom of a hill and we were going to trot, then canter up it. My friend went ahead and started trotting on her horse, but as soon as she did, Fergie leapt like 4 foot in the air, all four hooves off the ground without a warning. She done this twice then tried to bolt, I stopped her and asked my friend to stop, then we continued to walk up the hill. After a few seconds of walking, fergie reared up vertical and almost went over backwards. I decided it was a good idea to get off and walk her at that point because she was getting dangerous and if I had fallen off, we wouldnt be able to catch her again.
In the paddock we use for riding in, she will go along fine for a few minutes, then decide she wants to stop, and again if you try to get her to move she will buck or rear. Then she'll start moving again, and stop a few seconds later.
She's been doing this for a few weeks, but the bucking & rearing out on hacks seems to be getting worse and more dangerous.
Why is she doing this? Can anyone help?
I'll try to get videos of it next time I ride her, just so you can see exactly what she is doing.
She also grunts while she's doing it.
And when I was leading her through the field before I tacked her up, she reared & striked out at me. & after we came back from the ride, we were just stood in the yard, I had taken my feet out the stirrups while I was talking to a friend, and Fergie cow kicked & kicked the back of my foot...
Anyway, we really need help with sorting this as my friend is trying to sell her as she can't afford to keep three ponies, and fergie was sold to her as a beginners pony for her son, but she turned out like this..
Here are a few pictures of her bucking in the paddock from a few weeks ago..shes gotten worse since..
