The puppies begin dropping off to sleep around 8 PM, although there are a couple of “live wires” (different every night) who need a little extra running and snuggle time before they unwind and curl up with their littermates for the night.  A number of the puppies have begun to enjoy belly rubs which I’m not sure is exclusively a Griff characteristic, but it’s definitely a characteristic of every Griff I know.  They love having their bellies rubbed!
