Welcome, 6 weeks is really to early to bring a pup home. 8 weeks with his litter is recommended. Pups learn a lot from their mom, and littermates in those 2 weeks. German Shepherds are known to "landsharks". There are a lot of threads on best ways to raise and train your puppy. You can use the search engine or look under the puppy section for a lot of answers and ideas. Hope all goes well, and please share pictures. We all love puppy pictures.
