I never stretch a horse, it is not allowed, but I would think the method is the same wherever the feet end up!! Just stand in front and give your command (I say "Stand square") and then "jiggle" until they do it- it will take a while. Once they attain the pose you want for a moment reward and move them off the spot them start again. Eventually, with the correct rewards, the horse will stand as long as you wish. I would not even attempt to get the ears up and the neck out until the feet are rooted to the spot!! It can be fun!!! I love it when I have cracked it and whilst others appear to be attempting a round of WWF wrestling with their horses I just say "Stand Square" and get what I want!! This started in the dog show ring and I figured if a dog could learn it so could a horse!!
