Forget about "Alpha bitch". True Alpha dogs are calm and confident and do not bully.
Give her plenty of exercise and crate time and your Bulldog some private time with you. Up her obedience kills as well. Can you try herding or treib bal?
When did your situation start and how long did it last?
Myah is spot-on and aims to please in every other way.
Oh, and let me add....sometimes, the bulldog is in the wrong. He wants to assert himself as important and will come into a room and stare at her. Therefore, when Myah hears him even close, she curbs him, promptly. But they both have to stop. Ugh.
