See, I really like this thread because I am trying to obtain the same thing with my young mare... the thing is, right now until spring, she is about 1 hr 15 min. Away from me. So I can only get out there once a week.
And considering the ground is indeed still
(dang winter!!) and I don't have access to an indoor arena, it's not very safe to be lunging her. So I usually just groom her when I go see her. So, I've heard grooming and going on walks together for a good way to start bonding... any other suggestions?
