Thanks again that you decided for a rescue dog! Overall, rescue dog problems are much rarer than when dog owners decide for a puppy, then don't quite know what they are doing, miss out on comprehensive socialization and the right health care, and promptly they end up with a sick and/or aggressive adult dog.
Indeed, if they decide for a German Shepherd puppy and miss out on comprehensive socialization, then they often end up on MYGERMANSHEPHERD.ORG to seek our help with their "aggressive dog".
Anyway, you've got a rescue dog and a problem. No problem! Can all be solved, including trauma. So, don't you worry, and never give up on your rescue dog.
