Leesa - I can't help with how to make hims stand properly (not into showing), only suggest you talk to your breeder and take him to ringcraft - they will help you :)
Leesa, there's no magic spell, and no mystery. Regular ringcraft classes, and practice, practice, practice. It's important to keep the sessions short though,puppies get bored very easily. A few minutes a couple of times a day will be enough, and the penny will drop eventually. Dawn R.
