Thank you all for your insights.

Mickie does seem to be a happy girl these days, and we have congratulated ourselves on what a sweet, happy, friendly girl we share our home with. And, as we are not the youngest folks around, we are also pleased that she has a quiet disposition. I tease sometimes that she's a reincarnated cat: she sleeps about 14 hours a day, enjoys napping with any of us indulging ourselves, and is very happy to sit beside any of us and getting scritchies.

There are few dogs in our immediate circle of friends: I'll have to think about ways to arrange play dates for our sweet girl. And, of course, we'll continue to demonstrate doggie toys for her.
