I have ridden plenty of horses that get a bit hot and jiggy when ridden out on the trail alone, but my new mare is a bit beyond what im used to and comfortable with. She is a 10 year old quarter horse. We can ride out to a certain point and then she decides she does not want to go anymore. She will plant the breaks, and then start backing up. I make her do circles both directions, this sometimes leads to rearing but we can get past this point. After that point she gets increasingly hot, eventually spinning around, walking sideways, backing up, trying to trot and jig, sometimes bucks. It feels like she is about to explode underneath me. I try to get her working and thinking about something else but by this point she will not circle or bend just tries to turn and bolt. I get off and lunge her both directions, but then sometimes i cannot get back on her because she is so worked up. She is wide eyed and scared of everything around her. I bought her 6 months ago, and she was sold to me as a solid trail horse. I longest i have been able to trail ride is maybe 45 minutes. Today we made it 10. Its winter now she isnt being ridden as often. Riding with others isnt an option for me i can only ride alone. i fell so hard for this horse, she is such a beautiful mover wonderful personality at home, i would really hate to sell her. What can i do to work through this ?
