What breed of dog is she?

[lovemymaltese]

I found another picture of Roxey and this shows how big she is. She is a heavier dog. She was very over weight here. My papa was diagnosed with cancer and fought a hard battle before dying this past April. He stayed so sick and she would not leave his side. He never wanted to eat himself so he just fed her. It gave him comfort to make Roxey happy by feeding her, so we never mentioned that she was getting so fat. She has lost about 20 pounds since then and looks better. She is still a big dog without all the weight. Is this a better picture to determine the breed of dog? I do agree that she has some German Shepard in her. I cannot even begin to describe the happiness and comfort that she gave my papa in his life. She is an angel with invisible wings.
