As a fellow German Shepherd owner, welcome! I'm excited to see what the future has in store for us all. German Shepherd puppy pro tip, get lots of different chew toys for the teething period. I have awoken to her eating my phone, shoes, ect.... Overall, best thing that has ever happened to me was picking out my puppy some 9 years ago. I hope same goes for you.
