yes , it sounds as if you will never be able to let you r guard down, Question !!! you say Cutty did a head bite !! where on the head did he connect? Mila will likely be the queen Diva !! me original 3 had a female that ran the roost, she was alwys on !! should have shown her , but anyway, the threatened to her siblings at all times for all things, so much that they were on egg shells all the time. she never bit them, she made sure they feared her to much to challenge her! from 3 to 7 she started getting worse with guest dogs around, had a thyroid issue((that's the first sign of a thyroid being off is --aggression)))especially in Bulldogs. but she finally ripped a poor old deaf bulldog apart, that I had been taking care of, and dragged him around the house by his legs, I had to face the sad fact that she would have eventually turned on me ,at some point ,and never again should any dog fear her. I must say ,the other two dogs immediately relaxed, and the house was suddenly peaceful. Sadly!! the rest of the pack should not suffer ,because of one. so stay with this. she will get red zoned - in any room. for many reasons. keeping her out because of food, will just change her choice to toys, a spot on the floor,couch, you see what I mean? she is demanding her status be recognized no matter where. always make her the last dog to get anything, food,toys,in or out of any where. you will probably always need to be keeping her status grounded in all things. you are doing a good job. merry christmas.
