I recently found this site and have been browsing it for a while before deciding to make an account to address a problem. I just started leasing out a 6 year old Appaloosa mare, who is relatively fearless and does almost anything I ask of her without hesitation. However, her owner warned me that she gets 'a little nervous' when she leaves the barn, because she wants to be with the herd. 'A little nervous' has become standing still and refusing to move when I go to take her outside, even if I'm just leading her on the ground. This poses a problem, because sometimes other riders are occupying the indoor arena and I have no choice but to work her outside. Once I finally coax her out into the open, she stops being as responsive and has tried to run away with me in the barn on several occasions.
Can anybody give me advice on how to keep her calm and trusting once we move outdoors? I fear for both of our safety when she tries to run off and am clueless how to alleviate the situation. She does fine if another horse or people are outside, it's only when we go alone... I'm new to the barn and don't really have friends there yet, so I can't ask anybody to take their horse out with me.
