My Ginger is almost 11 weeks now. When we first brought her home 3 weeks ago, she was really shy and calm. For the past week, it seems like she is getting more and more aggressive. She is my first pup, so I don't know what is "normal". My husband and I leave her in the kitchen while we're at work. I come home for lunch to feed her. She has been barking and running around like crazy. She also has been biting all of us including my 9 year old daughter. Is this normal or is she just an aggressive pup? Any suggestions on what we can do to stop this, especially the biting, from happening? How old are they before they really understand what they should and shouldn't do? I'm so lost!!
