ok yes shelties are free standing, if her legs are out of place then it is up to you how you move them, you can either pick it up and put it down in the right place or risk putting all four legs wrong by moving her again and again. moving a leg will not count against you.
As for the rules if you win puppy and get beaten in junior BY ONLY JUNIORS then you still get Best puppy in breed so you can go into BEst puppy in show. BUT if you win BPIB and then lose in AV minor puppy u will NOT be able to go into BPIS.
At a pups first show i will normally only enter one class (breed) maybe once then are 9 mths i might enter them in two classes.
If two classes you enterd were going at the same time then talk to the stewards. They will hopefully then ask the judge if it is ok for you to leave the ring and go into the other class. what ever you do dont panic if this happens. You will just have to run between rings but let the stewards know so they no where you are.
Also at manchester i wouldnt recormend you doing all those classes, sheltie minor puppy bitch will be enouch. proplan pup of the year will be against older puppies of different breeds and special beg. stakes and YKC stakes will be up against older dogs and in the YKC you will be up against champion dogs in thier prime so i would not recormend that.
Saying all the above it is your chocie what you enter your puppy into and if you wish to enter in all those classes then it is your chocie but please think about your pup and champshows can get very stressful for them!:)
