Weird/out there question for dog shrinks

OK, I apologize in advance for this one. Seriously. I've debated whether to start it because it will probably lead to the kind of comments/discussion I hate.
Yet it is bugging the shit out of me (no pun intended, explanation coming) and I figure if anyone can give me an answer, it is someone in our world. Try to think of the topic/question and not the circumstances, please.

Been a dog guy all my life. Usually had at least two at any one time growing up, sometimes three (like now). Had lots and lots and lots of dogs and I love all of them.
Never had one like this.

I've mentioned before that one of my current sweeties is a tad special. Well, this dog is absolutely fascinated by me sitting on the, um, throne. It baffles me.
If I'm in there with the door closed, she goes absolutely apeshit outside the door. Just nuts. When she senses that's where I'm heading (frantic look on face as I search for book or mag, rush in the right direction), she darts in and lies down right on the side of the throne. Cannot drag her out of there.
She does nothing unusual while business is being conducted. Just sits there with this smiley look on her face. Leaves when the show is over.

The dog loves me a lot. But she doesn't go out of her way to sit right next to me other times, like now when I'm at the computer.

Help me understand, please.

 

Well there's that.
My dogs do love me more than anything or anybody.

 

Nope. This ain't one of those threads. Don't take it there. We're all growing up and moving on.
And I do want to know what's up with the shit-taking loving dog.

 

It doesn't matter which of the three crappers I use. She'll sit sometimes, lie down sometimes (hey, now and then it takes a while). If I'm not sitting, she isn't interested.
She lays on the shower mat, too, sometimes while I'm scrub-a-dub-dubbing but I've had dogs do that before.

 

Maybe it is the attention thing but she gets plenty of that. Can, um, ah, shit smell sweet to a dog?

 

Maybe it does to a dog. To the humans among us, no. Not at all.
