My wife is still working on being more consistent, firmer in commands and leadership structure with Lexi. I demonstrated, with my wife hidden so Lexi couldn't see her, that Lexi knows all the commands, sit, heel, down, stand. Flawless.
I did so after Lexi had growled and snapped at my wife trying to get a piece of what looked like plastic Lexi had gotten from somewhere. I had to step in and put an abrupt end to it.
I notice Lexi has been playing my wife. I had Lexi in her bed (mat, or climb) while my wife was gone. Only had to remind Lexi once. After my wife got back Lexi wouldn't stay there. Constantly getting up and pilfering as my wife and I were trying to talk; trying to act like she didn't know what the 'bed' command was, and kept looking at my wife when I would give Lexi the 'bed' command. Trying to see if she could just get close to her mat and lay down, as though she didn't know what she was supposed to do.
She has been intentionally controlling household interactions with her behavior and it stops now.
