I got my mare Blíğ when I was 8 years old (I'm 19 now) but I didn't start riding her until I was 10. We had the perfect bond, she always behaved perfectly and I could go alone on trail rides. I had rode her for 6 years and then my parents decided to give her away... But now, about 2,5 years later I finally got her back It seems like she doesn't think of me as her leader anymore. She wasn't very happy to be inside the stable (the other horses were outside) while I was grooming her. I'm going to have to start all over again.
What can I do to make her trust me again? Would join up work? I don't have any access to a round pen :( I'd love any advice you can give me
