Good to hear you're feeling fine. I would absolutely not tolerate this from any of my dogs. She's not saying she loves you, she's saying you belong to her. I would definately not tie her to the bed close to you when she's acting like this. She'd be in the crate when I'm sleeping. When she stares down cash or growls or lunges, its a quick eh-eh sound and either a command to the kennel or a send away command. Something that will absolutely give her the message that you will not tolerate this. There is no reward for her and no apology on your part during this time. You may feel bad because you yelled at her but she isn't getting hurt. She's going to try and tell you she's getting hurt so you stop correcting the behavior she wants to do.

And correcting her in this situation will not make her useless when a stranger comes to rob you. Its much harder to fix a problem the second time around when you tolerated it so well the first time.
