It's all in your facial expressions. Show dominance, but try and focus on the ground rather than her face. Let her sit next to you in EVERY spot you will be sitting in. Make her an equal. Be slow when showing dominance.... Like, when picking a spot on the couch, sit with confidence, then look at her, like you are confused as to why she isn't sitting next to her. She will understand, almost RIGHT away. My mom used to train golden-retrievers for the disabled. I saved my girl from a fucked up family that used to leave her outside in -10 cold, on top of beating the shit out of her. She has a low tolerance for bullshit anymore. What a good girl though.
