I have an older horse I just got who is about 18. Quarter/Paint. I bought her from a young boy about the age of 22 about a year ago and I still have yet to figure out what she might have been used for. If I ask for anything more than a walk she goes straight into a gallop. One rein stops, change of bits, spinning in circles.... Nothing seems to stop her. Even when she is being lunged. She just runs full out and never gets tired.
I really don't know how to handle her because everytime I ride her its a fight to hold her back. We have worked the fence line, she reins like a charm. I guess she just loves to run. Help anyone?
