I have a gorgeous 11 week old german shepherd puppy girl and she hates going out the house,she is so scared she wants back in the house straight away ,when I get her to walk away from the house and if she sees people she growls and barks at them non stop.She even does this to dogs.I have never had this problem before with a puppy so its new to me.I was thinking of taking her to dog classes 2mw but will this make her even worse being around lots of people and dogs ?
