If your kids are old enough, have them be the ones that give her, or hold as Jenn suggested, any bones/treats and her food. And before she gets them she must sit/down for the children, not for you or your husband. She needs to start recognizing them as being in charge too.
Navarre was that way with his food and I started making him eat his dinner out of my lap, which he didn't like because I would be above him, or he had to eat it out of my hand. Then I put my hand in his bowl while he ate, I'd just watch TV and let him eat. At first I wouldn't move my hand at all, then after a few times I would move it a little. I took it slow but it worked for me. Now, I'm not saying to have your kids do this but maybe you or your husband should even though she doesn't growl at you there is still a food issue there. Good luck
