Hi,
I start showtraining as soon as I can - from about 7 weeks - at every mealtime I try to get the pup to stand still, all 4 feet on the ground, before I give him his food. (I also hold the bowl at pup's chest height, so that a) he doesn't start guarding his food from hands, and b) so that he doesn't spoil his shoulders). Then I progress to making him stand a little longer and in a better show pose, telling him to 'stand'. By the time he starts ringcraft at about 14 weeks he should already have grasped the basic idea.
And once in the ring,
don't give the bait just before the judge is going to go over him!! Put it back in your pocket/bumbag until when your turn is over. Then praise, praise, praise and treat. (And
never throw the bait on the ground - it's infuriating for other dogs and handlers.)
Good luck!
