Ok so I've been riding for a while...used to show in hunter jumper competitions and win ribbons. Got out of it for a while, back into it, back out of it...but I've been riding again for over a year and progressing well (in my opinion). I am leasing at this barn where I can ride any horse she has for sale 2x a week. I'm more partial to stocky breeds like quarter horses and paint horses, but I realize I need to 'expand my horizons' and try riding different breeds, horses etc...SO I go out to ride today and the horse I have ridden the last couple times had been sold so she suggested I try a TB that has been for sale for a while. He jumps and everything, his owner just doesn't have time to ride him a lot. So I figured I'd give it a go. The woman who owns the place, who suggested I try him, told me he pins his ears back when you ask him to trot because his feet were sore for a while due to wet weather but he now has shoes on him and he's perfectly fine, so just 'push him through' the ear pinning and he'll be fine. So I was a little excited to ride such a 'well trained' horse that I could get back into jumping with. I got on him and walked around for a bit, made sure he was listening to me and then asked him to trot. He pinned his ears a bit and tossed his head up, but I continued to ask him and I got a bit of a jog out of him for 1/4 of the ring and then he just stopped and refused to trot anymore. He would pin his ears, toss his head up and if I continued to ask he would turn his butt in and kick out with one of his back legs. So I told the woman he wouldn't do anything. She lunged him and he acted like an ***, but proved that he could MOVE. So she got on him. Walk, no problem. Trot, tossed his head for a second and pinned his ears back and then trotted on as asked. She even got him to canter! So I'm not one to be 'beaten' so I said I'd give it another go. Thinking he just got 'warmed up' and he'd be fine. He absolutely refused. he would walk but as soon as I asked him for more he would continue his little tantrum act. She said just to get a different horse because he was obviously just 'pushing my buttons' and I was obviously going to get hurt (she didn't say that but I could see it). Anyway, it's really frustrating to see someone hop on a horse and see it behave and then you get on and the horse wont do a THING! Have you guys had that experience?
