I found this over at http://halt-near-x.com/blog and I thought is was super cute so I decided to steal it and bring it over here. Enjoy!
1.Make sure your horse’s ground manners are generally good. She should halt immediately when you say “Whoa! WHOA! Good gir—no, don’t move! Don’t mov—good girl. Stand there. Just stand. No, WHOA!”
2.Pick a strategic location to start her training. Avoid the barn aisle outside her buddy’s stall or a place in sight of the feed room/hay shed.
3.Place your brushes, saddle, bridle, and everything else you need to tack up nearby.
4.Lead her to the location where you want her to ground tie. Halt her and tell her she’s a good girl and feed her a treat.
5.Move away a step or two to grab a brush. Remove horse from back pocket and return her to the location where you want her to ground tie.
6.Repeat Step 5.
7.Repeat Step 5.
8.Move away a step or two to grab your saddle. Fetch horse from the far end of the barn aisle and return her to the location where you want her to ground tie.
9.Repeat Step 8, this time fetching horse from the hay shed.
10.Give up, tie horse, and finish tacking up. Go ride.
11.Repeat above process after your ride, in reverse.
12.Turn horse out. Watch her immediately bury her head in the grass/hay and not move for the next half hour. Success
