Horse is being a straight up *****, help!?
There is really no other way to say it. She is an OTTB rescue so she has her quirks, but she just fights and fights and it is frustrating. She would not even trot down a longside today. When trying to get the trot she throws her nose in the air, hollows her back, pins her ears, shuffles her back feet around, twists her neck from side to side, and will try to go sideways instead of forward. This all happened in our ride today and I urged her on when she tried to go sideways and she reared and threw me off. I'm stuck, has anyone else had a horse that does this or have any kind of suggestion? Please note that the owner and I are fairly certain this is not a medical problem. She has seen the chiropractor, her feet and teeth are fine, etc. This is a behavioral problem
Thanks for the answers so far. To address some of the things I saw- I do not own her, she is my lease. Her owner groundworks her. Her saddle has been properly fitted, and trust me her owner has done plenty of searching. She has been off the track for four years.
A rider that was out there when this fiasco happened said that since she is a racehorse she has a lot of the neck muscles that she can use to resist me and not a lot of the other muscles that other dressage horses have to use their hind end and stretch long and low. She suggested lunging, and I will start lunging her in side reins to help build those muscles, but she lunges perfectly fine. Her owner experiences some of the same issues with her, not all the time but she does (and I have not been leasing her very long). So I am looking for some exercises to do under saddle?
