Thank you so much for the advice and the welcome!

Well, Nibblet is in her new, rigid plastic pen. (That whirring noise is her little brain trying to figure out, "hmmm..... This is different.... What to do; what to do!") She gives me
The Yorkie Death Stare every so often, but so far the X-Pen is still intact.

We also went on a loonnnnnggggg walk, and she went wee-wees!!!! No poopage, but she did wee, and I think she was
thisclose to making the connection of what outside is for. Mostly I let her sniff around and run (but not too far - I just played out the lead a teeny bit). She slept for about an hour... And now she's up. (Yay...?

)
So here we go! Like Bette Davis said in "All About Eve", fasten your seatbelts; It's going to be a bumpy ride!"
