If you want to show you dog in open shows, champ shows etc... She will need to be KC registered to enter them. Go to ringcraft lessons they will help you on how to stand and show your dog. How do you mean by "Chunky"? as they are some chunky looking siberians out there. It depends on what Judge you go under some prefer the working types like mine and others prefer the american lines which have a thicker coat making them look more chunky. Both types are fantastic, or try to go under an all rounder judge that likes both types.
It just depends on the judge you go under on the day. They judge on looks, movement, confirmation and how the dog is handled.
Good luck
