Somebody's been sleeping in MY bed

We are a dogs on furniture household, that much is very apparent. Elka also sleeps with us, which is sometimes more pleasant than others.

She's also started a behavior that I had only heard about, never seen, until recently. Evidently, when I'm at work and if our room door is open, Elka will go upstairs and sleep on our bed. She doesn't mess with anything, trail clothes around, nothing. Just goes up and sleeps. She did this even before we got the new couches, which made sense because our bedroom is very warm, but with the new couches, she does it even when I'm here.

The first time, it was a little startling. I emerged from the shower. My fiancé and housemate were going about their business. No dog. "Where's Elka?" I asked, trying to play it cool, but seriously? Elka is never not there.

"Oh, she went upstairs," my fiancé said. Oh.

Since then, I've watched Elka make her trek upstairs. She plays it cool, circulates around the downstairs a little bit first. Perhaps she's testing whether she's interested in her toys still, or if the bed's siren song is too much?

Whatever the case, there's the point at which her circuit takes her to the bottom of the stairs, and then, well, she might as well go up. She goes up slowly and quietly. Her tags don't even jingle. I don't know why this solo-bed-using seems illicit to her. As I've said, she's proven we can trust her up there. Nothing pulled out, chewed, whatever. 

She comes downstairs if you call her, but sometimes, even the sound of my getting tupperware out to put the leftovers away doesn't bring her down. This is normally a Sure Thing; I frequently give her the leftover veggies from dinner, you see, if there isn't a quantity such that it makes sense to save it.

Of course, I pretty frequently think it's weird my dog likes broccoli and green beans so much, so it's just as well.

When it times for me to come to bed, she welcomes me affably enough. We never have "bed wars", other than of the play sort. I tell her to move, she moves. Frequently, she stands and watches me lay down, so as to burrito under the blankets in the most thorough manner.

There are also worse things than having a prewarmed bed, especially in January!
