"YESTERDAY I FED HER AND PUT HER OUTSIDE. SHE SAT BY THE SLIDING DOOR AND WHEN HE CAME UP FROM FINISHING HIS FOOD…SHE LITERALLY ATTACKED THE DOOR FROM OUTSIDE AND HIM FROM INSIDE."
Just a thought........Do you think, in this circumstance, she might have felt she was missing out on something by being excluded from the males feeding time? If they have to have separate feeding times could you keep her on a short leash with you giving praise and dinner kibble as a treat for good behavior while he eats?
From what I understand "the house" is her territory (as she sees it) and you are inside the house (also her territory). Do you think it would make a difference if she was in the house and he was fed outside? If separate kennels are not an option so that they are fed at the same time, how about an area where you could use a toddler gate? Just remember to remove both dinner bowls before you re-introduce the 2 of them!!
I'm just a pet owner with no professional knowledge, so I may be way off base here. Perhaps others with introduction experience specific to your case will chime in again. Good luck and keep us posted as you begin to try to re-gain your alpha position in the house.:)
