My breed isn't 'stacked' at shows - they all freestand. The best way to teach this is at pup's mealtimes. Instead of teaching him to 'sit' for meals, titbits etc, tell him to 'stand'. When he's in the right position (all 4 feet on the floor, preferably roughly in show stance), give him his meal (and lots of praise) as the reward. If, at the same time, you put your right hand in your pocket while holding his bowl, he'll learn to 'stand' for anyone with their hand in their pocket! (Can be very embarrassing at shows - my bitch would 'show' for anyone!) As he gets better at it, you can refine the 'stand' position. This method has always worked for me.
