german shepherd behavior

Question
I have a 18 month old female sherherd. She is verk kind but she goes crazy when people are around our house especially the mailman. Her hair stands up on her back and I thinj she wil go through our window. She also does not like our one neighbor and I think if she getsa close to him she might bite. Any suggestions?

Answer
Hi,

German Shepherds are very protective of their property.   Your female is going to protect you from whatever she feels is a threat.  If she accepts people once they have come into the house and been greeted by you this is fine.   If not you are going to have to work on her, and I would start with some basic obedience classes.   The mailman probably does not have time to get to know her, but perhaps he can throw her a treat.  Same with the neighbor if they are willing to get to know the dog.  Keep her leashed at all times when she is out of the yard.  If you give me more info on how she acts in different situations, I could give you a better answer.  So feel free to do a followup question with more info.
