Dog showing dominance?

In this case you are the Alpha to her as she listens to just you..What you are describing is'nt good as the dog should'nt show teeth to anyone in the family and this could be dangerous.How long have you had her?? You can be correct that the reason she acts this way toward males is because she was abused by them in the past.I would think that your husband and son need to take the dog for obediance training so hopefully she will learn to listen to them also..But this sounds like a disaster waiting to happen
