Ya that what's I figure. The thing is she wasn't always like this, it seems as she get's older it get's worse. She's never been aggressive to me, and I take her bones away often, and I've taken food from her too, especially food that someone was careless with and let her steal, I never let her eat food that grabs off tables, I don't want her thinking that's ok too....

Will having her spayed calm her down a bit? I know male dogs calm down and lose a lot of aggression when they get neutered, but I don't know if the same happens for females.
