The SKN Practical course must be done with each dog acquired after 1 September 2008. So yes, you should do the course.
(That's the federal law. However, we have seen on many threads that not all cantonal or commune officials enforce the law.)
Some confusion as to the Theory course comes in with foreigners who moved to Switzerland after that date. So if you have questions go straight to the source, the cantonal veterinary office.
But... As I say on every SKN thread
I recommend that all newcomers do both courses even if excused. It's a good introduction to Swiss law, manners, mores, and expectations - imformation you will need as you and your pup settle in.
And remember: there is no test, attendance is all that is required.
Here's hoping you and your pup enjoy your Swiss adventure.
