I'm getting a new puppy in a few months. I have a 4 year old dominant female German shepherd dog. She has never started or looked for fights with other dogs. If another dog gets in her face she will get annoyed and "pin" them. She has never hurt them though. I was wondering if any one has any advice on a good introduction. When I first adopted her she was great with my parents dogs. They were polite when they met her.... I know the puppy will be crazy(working line gsd pup) and probably try and jump all over her.
