OK. if you want to use a stick and your animal has a problem with them, make sure you run the stick down the animals leg before you go and stab him between the toes. thats where most people go wrong. if hes still funny about it, just keep practising.
i used to use another way with animals (i showed for a school so show canes were sometimes in short supply) and the more you practise this technique with the animal, the better he will get at it. when you go to pull up, hold his head up high and stop suddenly. 99% of the time he will stop square. this make take a few turns to master but after a while, you will see the animal actually doing it himself.
also. if hes not square, turn his head to the side with the leg you want to move back, and push gently back. again. after a while, all the animal will need is slight push and he will square himself up.
