Have you taken her to any training classes? If I were you, I would search for a reputable trainer with LOTS of Rottweiler experience and have them come to your house to observe the behavior in person. Personally, I don't think anyone should be giving advice to put a dog down in a situation like this without seeing the problem firsthand. Perhaps their advice will be the same...but I don't think it's fair to the dog to make a decision without consulting a professional in person first.
