We are one week in to owning our first GSD puppy. She'll be 9 weeks on Friday and we are dealing with some MAJOR control issues. When inside she listen's so well...comes when we asked...reacts well to a strong "NO!" when nipping...sits...stays...she's great. The second we put her in her backyard all **** breaks lose. Suddenly it's like we don't exist....we can yell her name...whistle..clap...im sure we could sound an alarm and she doesn't even turn her head. She'll hide under the deck so we can't get her and this is where we're hitting a training road block. We are hearing that we shouldn't be scolding or pulling her out as that is a negative consequence and we don't want to associate ourselves with anything negative this early on. Any ideas on how to get her to come to us with out physically pulling her away from where she is or yelling? We want to make sure she trusts us but are scared she'll get out or get away from us and then we'll have no way of getting her attention back! HELP!!
