I just recently purchased an 8 week old blue dobi. I seem to be having issues with her. Now I have had several dogs in my past but never a doberman.
One major issue I have been having is she snaps at my 3 year old mutt. Now I have read that it means she is being dominant but I am uncomfortable with that due to my wife doing dog grooming from home and don't want her chomping/snapping at other dogs. The picture below is my puppy any my mutt.

Another issue is I have been having is her poop and pee is very inconsistent. She poops very little and pees frequently but it's never alot. Is this normal?
