Pets

Of our current 3 dogs, one is fed in the kitchen, one in the dining area, and one in the bathroom. I think we've avoided food aggression this way.

I would get dog muzzles for the immediate situation, until you can get some other answers. I just get the cheap, easy velcro kind, where one strap goes behind the ears, and one around the muzzle. I learned the hard way to use these when introducing a new dog to the pack, until everyone figures out the rules. They come in different sizes.

Is the female a new dog? It sounds like she's trying to establish dominance over the others. I would definitely muzzle her, and do some obedience training, so she figures out you are top dog.
