I have had my 10 month old GSD for around 3 or 4 weeks. He has been pretty good when no one is home and left alone. But tonight we came home and he had ripped the blinds off of the back doors. They are destroyed!!
He also chewed a toy gun and a Christmas present bag. It looked like he saw something or heard something at the back doors and wanted to get at it.
I didnt want to yell at him cause i dont want him scared of me, but i dont know what I should do if it happens again or where to go from now. Let me know what you all think about how to handle this situation.
