First time GSD owner here.....We are planning on bringing an GSD puppy into our home the middle of September when he is 8 weeks old and ready to be picked up from breeder. Of course vet checkup will be within a few days after and then we are planning on a dog trainer to come into our home to train and assist us in basic obedience training. So my question is I know the dog will take commands from myself, my wife, and my daughter; however what about other family members who come over often like in laws and my parents? Of course I am going to make sure it socializes with them whenever they come over or when I take the puppy over to their house. Bottom line is yes I would want to take certain commands from other family members, but not some random strager obviously, do GSDs or dogs work that way gerenally speaking?
