Yes, I am gonna jump on the pile. Association with work. Don't always make her stand after she is caught. Take her to graze, let her eat. Walk around with the saddle on, maybe. Give her treats with the halter in hand. Make her associate the halter with something besides work and besides standing. What I did is I would take a sunchair out to the pasture in the summer and I just tied a whole bunch of halters to it and tanned out there. Soon enough I had horses looking at me and coming to see me like "WTF? Since when did you start tanning here?'
