>>Doggy deep sleep, that time when they have dreams chasing rabbits, growling, yipping, is only deep sleep because you are there and they know they have a lookout.
A fascinating point which I had not appreciated and which explains a lot.
My dogs would spend the early part of the night and the end of the night in the children's bedrooms. But the rest of it active and wandering around the house and garden fiddling about with various things. If a hole was to be dug, something was to be chewed or something was to be stolen it always happened at night.
That whole deep sleep with a lookout thing makes so much sense.
