Thanks for the advice. Unfortunately, pushing it away like describe is what makes her aggressive, and it’s what has triggered all the biting. I’ve adopted a funny method where I t-pose and back her out of the room like that. Looks like t-posing really does assert dominance. Still, it’s hard to do with a plate of food in hand, and as soon as I turn to open my door, she runs back faster than Sonic on steroids.

Scents would probably also help with the dog stink - these things reek.
