Hi, my name is Mary and I brought home my 8-week old GSD on Monday. His name is Hank. He weighs 15.5 pounds. I am a first time dog owner (I'm in my 40s however), and chose a GSD after having the privilege of knowing two of them for the last 6 years. In fact, Hank is great-nephew to those two. In any case, the last 6 days have been somewhat overwhelming. I want to do everything right. We are starting puppy class but not for another 4 weeks. Hank is very good overall and very good at potty already and a good sleeper at night, but he wants to chew everything (normal, right?) and the last few days he has been getting pretty serious about nipping at my hands. Any advice on that? I have been giving him a stern "NO BITE" command and holding the scruff of his neck until he stops (not to cause pain, just to get his attention). I'm sure I will have a lot more questions and I am very grateful to have found this forum. I would love to hear any and all advice for first-time owners.
