My dog gets me up usually around 3:00 - 3:30 a.m. It's not so much that she has to go potty, I think she just wakes up then and says to herself, "Hmm, I've been sleeping in this big ole warm bed with my mom for awhile now, it must be time to go play in the yard!" I usually just let her out, flop back in the bed, and then when I here her at the door I let her in, and flop back in bed.

Now, my old guy, Shadow, he'll sleep all night and gets up only when I do at 8:00 a.m.
