You did ask how it is in germany and not how it is in norway! But are you allowed to show csw in Norway in dogshows? No, of course not. They would take away a csw at the border and kill the dog. So you see the difference! When I remember right, there are list from the dogs who appear in the shows on the website of the vdh. Here are the results from two weeks ago, please scroll down there you find the csw:
