Thanks for the info! I just took her a couple weeks ago to have her checked, spayed and all of her first shots. Her teeth look great and are very strong and sharp. The reason I worry about her aggression is because my other dog is also a rescue and she is deaf. She gets scared very easy. She was actually getting ready to be out down and we rescued her. I guess nobody else wanted her cause she was deaf and they read all of the misinformation online about deaf dogs.
