Hello fellow horse people. My family and I are new to the horse owner world and I would love to share our story so far and get feed back on some questions I have. Before deciding to buy our first horse we bought books and found a trainer. We took lessons for a year learning what we could about riding and owning horses. Our trainer finally thought we were ready and we started the surch. We found several horses that were worth looking at the first hand full ended up not being quite right. But then we found my mare "luna" she is perfict supper gentle and sweet and we had a bond almost instantly. She has been happy with us here ever since arriving on our mountain ranch. After finding my mare we still needed to find a horse for my partner, we once again looked at several before finding the one we thought. We went and looked at this guelding with our trainer. Our trainer and my partner both rode the horse to make sure it was safe and what we were looking for. He seemed ideal he was calm, he did not seem to get agitated at any thing and most of all seemed like a quiet easy going trail horse. So we went ahead with bringing this guy home. When he got here there were no real arguments between him and my mare all seemed like it was the perfect fit. When we went to try to have our first ride on him at our place a few days latter. We got him all saddled up and watched for any signs that there was a saddle fit issue or any agitation in the horse. We did not see any thing. After my partner get in to the saddle and asked nicely to walk on with no warning at all he he bucked and bolted off, then not more than a min latter returning to where my mare was tied at ( near where he bucked and bolted from). My partner got pretty badly injured with 8 ribs broken in several spots and bad concussion and a broken shoulder blade and punctured lung. He had to be taken by helicopter to hospital and spent two weeks in the hospital and have surgery. When the accident happened i let our trainer know what happened. She could not believe it and us being new. We did not know what to think we thought maybe it was a improper saddle fit issue that we missed signs of. Our trainer said she would come out and put a ride on him at some point and check things out. Latter with a different saddle after working with the horse more and giving him more time to adjust. This saddle was and even better fit and trainer thought so to. All should have been fine. It was not once again this horse have no signs of any issues or agitation he was alert but not showing signs of being possibly dangerous. Our trainer got on him and all seemed good. Next thing we know with no warning he bucked and bolted and kept bucking till he finally dumped our trainer.( Luckily she did not get hurt.) And once again he calmly returned right to where my mare was at. My trained decided it has got to be some thing with my mare. We are thinking he was fixed to late in life or some thing we are not sure what thw issue is but he is unpreductalbe and unsafe for us. She feels awful about the situation and all that has happened. The old owner won't talk with us but our trainer he will. At first when my partner got hurt by this horse he offered to our trainer to help us find a different horse and take this one back but then latter told us no I will help you find a new horse and I have one for you but you have to buy that one from me and we have to sell this one. After our trainer got bucked hard off and saw for her self what he does here. She contacted him again and said he needs to make this right suposidly he is but he is out of the state for more than a month and he still has not really comunicated with us. Our trainer promises to us this will get fixed and she will do what she can to make it right. But I guess I am having a hard time trusting that it will be made right. We bought this horse thinking it was one thing and in all reality here it is not. Should we expect this guy to actually take this horse back and give us our money back or is this just part of the risk you take when buying a horse? Just feeling a bit lost and so many questions running through my mind.
