LOL. How I miss those days (kinda, sorta, maybe not). Koji was like a child, would fuss and then whomp, out cold. But the puppy bob, too cute. FYI, amazingly, Koji doesn't do the "bob" when he falls asleep like that. He just closes his eyes (eventually) and his head stays up. He'll stay like that for a few mins then either wake up (sorta) or put his head down and go to sleep.
Know that it is not just a puppy stage. I knew my Cleveland was gravely ill when he started it again after years of not "going on the nods." It scared me when it showed back up in him.
Now MMM still does this, so he just may not outgrow it. I love it when it is just plain tired and not wanting to miss a minute of excitement.
