Problem with trail riding
A week ago I fulfilled my dream and bought my very first own horse. It is a 10 year old warmblood mare and she is calm, loves to cuddle and I bought her as "fool proof". However, I wanted to ride her out in the nature a bit last sunday. She tried to turn around and go home again, but kept calm and I could just turn her around and ride on. I thought that maybe she was just trying if she could get away with that stuff. But on thursday I wanted to ride her on a trail again and she did the same stuff. At some point, she freaked out, walked backwards and tried to rear. The worst thing is that I couldn't get her to move on, so I had to ride back (I didn't return directly to the stable though, but rode a bit down another path).
Before I bought this horse, I tried her twice. Both times I rode her in the arena and in the nature. (once alone and once with another horse) She didn't show any signs of disobedience back then. Since I had a vet check done before I bought her and the saddle fits, I don't think it is a health problem. When I'm riding her in the arena, she is completly normal. The horse is on the field every day and so far I haven't moved her to a new stable, so she is not in a stressful situation either. When I come to the stable, she whinnies and comes running in trot, so I doubt that she just can't stand me.
I have been riding for about 16 years and also trained young horses, or horses that were out of shape and not used to having to work, but I never had that kind of problem. I am one of the riders that easily get scared, that is why I wanted to buy a "fool proof" horse.
Did any of you have a similar experience? Did any of you have a problem with a horse that was disobedient outside and did you solve it?
Thanks for your advice!
