thx for all the advice and all the "my horse does that too"s. the solution is a crop. last tues we had a showdown. basically she did all the same stuff, but this time i had a crop. started normally by asking her to move, then moved on to me telling her to move (with heavy leg and vocal cues), and when that didnt work i demanded that she go (wih a solid quick pop from the crop). she still really didnt want to go, but i think she realized that i was serious that time. sooooo, on to today. im just back from a ride and she pulled this again today, but at the barn instead of gate. i tried the one solid pop and she still didnt go, so i followed that with light pops repeatedly until she made a step forward. as soon as she made a step (still very stubborn about it) i stopped and told her good girl. we did this for about 5 paces then she decided she better go. was fine after that. went out the gate with no problems. again, why can't we do that from the start?! ugh. but its getting better. i figure she will stop completely in a few weeks. she has these patterns that she goes through.
