Get them used to being on a lead, to stand still, you can also do this at home, use treats etc to keep their attention - have them stand and another person run their hands over their back and down legs and tail - go in their mouths, I say "Teeth" to get them used to this, I also say stand when I am standing etc etc Get them used to walking up and down or in a triangle and then stack them again I also use the word "show" when doing this...Ring craft is a fantastic way of teaching your dog just what is expected of them in the ring and helps the handlers understand too. It also gets them socialized with other dogs and people.....Good luck
