Awww what a total sweetheart! I too love the one of her laying in the pool. She certainly deserves a wonderful forever home. I do hope that if your sister and family fall for her that they will be responsible and give her what she deserves. At least they are fostering rather than jumping out to get a dog only to rehome the poor thing later. I certainly understand your frustration in watching her go through dogs, you must feel so helpless.
