Biscuit is lovely, but those ears could tell many a tale. I'm not so sure about GSD. What I am sure about is her beauty! I can see how captivated you were by her lovely, blue eyes. Were you given any clues as to her lineage when she was acquired? How did you find her?
We have many threads, especially for the first time puppy/dog owner in our Behaviour Section, so please give that a good read. You sound entirely enamoured with Biscuit, which is the best place to start! We also have a "Breeds and Mixes" Section which may provide you with some clues.
