My B never tells me it's time to get up, but we have a routine. He sleeps on the bed under his very own blankie, the alarm goes off, I get up, shower, clothe, then go to the bathroom to brush my teeth. That is his clue, when I brush my teeth, he knows its time to get up. If he doesn't, I go find him. It is kinda like waking a teenager for school. Fortunately, that is an infrequent occurrance, but I have to pull 'his' blankie away and kindof prompt him to get his butt up. As earlier noted, it is the cold. All this goes out the window when it is warm, sometimes.
It is all part of my pleasure of owning a dog that is not in any way typical. I love that he "purrs", tell that to your friends!
