My two are so different. Tucker wakes up early and will scratch his collar so the tags jingle. That is my cue to get up and let him out. Hannah is a late sleeper. She is the last one out of the bed. I used to drive myself crazy trying to get her up to go out with the early riser. Once I got her out of the bed, she didn't want to go outside and I'd have to chase her around the house before I could get her to the door. We have now reconciled ourselves to her preferences. The rest of us get up and go about our business. Sooner or later she appears. By this time my husband is already having his breaksfast and he generally saves some of the toast crusts for the dogs. I tell the late riser, "First you go out, go potty, then you can come in and have your 'toastes'". Works like a charm!
