Mine does this exact same thing Jon! Not very often though, just a
few times on cold winter nights or mornings. Never seems to hurt
anything but I would also like to know what it is. Mine is more of a
"moaning" sound like the Dak is saying "ohhh, c'mon I don't want to go
anywhere now, just let me sleep...."
