Just want to say thanks again everybody! Bailey is already doing so much better! She is such a fast learner!
Biting- I finally got around to trying coins in a can. I shook it when I said no. It made me feel bad because it scared her to death, but 2 days later she definitely knows the word no! She backs off as soon as I say no, even when I don't use the can! Now company is another story. She knows biting me=bad sound. She still thinks biting other people is fair game.
Separation Anxiety- Well, she survived being left here alone for 2 hours. The whole time I was gone I was a nervous wreck, imagining her tearing up her pads, going potty all over, whining the WHOLE time, etc. I even called the house once to leave her a message.

Now I'm sure she whined and howled for a while, but when I walked in the house she wasn't even standing at the gate. No accidents, but she hadn't gone potty at all. However, after a little while home I left for 10 minutes to take a walk, and when I came back I could hear her howling from outside.
Oh well, baby steps. I am already so encouraged with her progress.
