I totally understand the idea of leaving well enough alone much of the time. Unfortunately, in our house, the whole "let sleeping dogs lie" thing tends to be more literal.
You see, the pup has a tendency to want to sleep just in the wrong places. And she's remarkably difficult to move for a dog weighing only about twenty pounds.
In bed - especially this time of year - she'll creep up to between our shoulders and then decide to stay there. Sometimes it's fine. Sometimes - like the other morning - it's not so fine. She moved into place when I rolled over to hit the snooze on my alarm and left me lying on about 8" of the edge of the bed.
Tonight, as I sat down to write this post, she hopped up on my lap and stretched out across my legs. Perfectly placed so that I couldn't even set my laptop down. Luckily, she shifted when I started trying to type.
So I guess, in this case, it might just be best to let her lie after all.
